energy demand in many countries worldwide is used to cover public energy demand for road, square and other public spaces’ lighting. Renewable energy can contribute in a significant way to the electrical energy demand coverage for public lighting. This paper focuses on the sizing and design of a hybrid energy system (HES) exploiting the solar-wind energy potential to meet the electrical energy needs of lighting roads, squares and other public spaces. Moreover, the proposed HES provides coverage of the electrical energy demand for a Wi-Fi hotspot and a charging hotspot for the end-users. Alongside the sizing of the energy production system of the proposed HES, in order to ensure a reliable supply without interruptions, a storage system is added and sized. Multiple scenarios of energy consumption are assumed and applied in order to optimize the sizing of the energy production system and the energy storage system. A database with meteorological prediction data for 51 areas in Greece is developed in order to assess the possible deployment of the proposed HES. Since there are detailed meteorological prediction data for all 51 areas under investigation, the use of these data is evaluated, comparing them to real meteorological data. The meteorological prediction data are exploited to form three hourly production profiles for each area for every month of the year; minimum, average and maximum energy production. The energy production profiles are combined with the energy consumption scenarios and the sizing results of the energy production system and the energy storage system are extracted and presented for every area. Finally, the economic performance of the proposed HES in terms of Levelized cost of energy is estimated by calculating and assessing construction, operation and maintenance costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20production%20system%20sizing" title="energy production system sizing">energy production system sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=Greece%E2%80%99s%20deployment%20potential" title=" Greece’s deployment potential"> Greece’s deployment potential</a>, <a href="https://publications.waset.org/abstracts/search?q=meteorological%20prediction%20data" title=" meteorological prediction data"> meteorological prediction data</a>, <a href="https://publications.waset.org/abstracts/search?q=wind-solar%20hybrid%20energy%20system" title=" wind-solar hybrid energy system"> wind-solar hybrid energy system</a>, <a href="https://publications.waset.org/abstracts/search?q=levelized%20cost%20of%20energy" title=" levelized cost of energy"> levelized cost of energy</a> </p> <a href="https://publications.waset.org/abstracts/143514/hybrid-renewable-energy-system-development-towards-autonomous-operation-the-deployment-potential-in-greece" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28248</span> Sizing of Hybrid Source Battery/Supercapacitor for Automotive Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laid%20Degaa">Laid Degaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Bendjedia"> Bachir Bendjedia</a>, <a href="https://publications.waset.org/abstracts/search?q=Nassim%20Rizoug"> Nassim Rizoug</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkader%20Saidane"> Abdelkader Saidane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy storage system is a key aspect for the development of clean cars.

The ESS operates in a hybrid configuration and consists of two unique technologies operated in a coordinated way. Based on given energy profiles and economical data a model calculates financial flow for ESS investment, including energy cost and ESS depreciation resulting from degradation. The optimization strategy proposes a hybrid set of two technologies with their respective power and energy ratings to minimize overall system cost in a given timeframe.

The AEA concept assumes that all aircraft systems will be integrated into one electrical power source in the future. The principle of the electro-thermal system is to transfer the energy required for anti/de-icing to the protected areas in electrical form. However, powering a large aircraft anti-icing system electrically could be quite excessive in cost and system weight. Hence, maximising the anti/de-icing efficiency of the electro-thermal system in order to minimise its power demand has become crucial to electro-thermal de-icing system sizing. In this work, an enhanced methodology has been developed for conceptual sizing of aircraft electro-thermal de-icing System. The work factored those critical terms overlooked in previous studies which were critical to de-icing energy consumption. A case study of a typical large aircraft wing de-icing was used to test and validate the model. The model was used to optimise the system performance by a trade-off between the de-icing peak power and system energy consumption. The optimum melting surface temperatures and energy flux predicted enabled the reduction in the power required for de-icing. The weight penalty associated with electro-thermal anti-icing/de-icing method could be eliminated using this method without under estimating the de-icing power requirement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircraft" title="aircraft">aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=de-icing%20system" title=" de-icing system"> de-icing system</a>, <a href="https://publications.waset.org/abstracts/search?q=electro-thermal" title=" electro-thermal"> electro-thermal</a>, <a href="https://publications.waset.org/abstracts/search?q=in-flight%20icing" title=" in-flight icing"> in-flight icing</a> </p> <a href="https://publications.waset.org/abstracts/9616/enhanced-method-of-conceptual-sizing-of-aircraft-electro-thermal-de-icing-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9616.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">517</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28245</span> A Teaching Learning Based Optimization for Optimal Design of a Hybrid Energy System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Rouhani">Ahmad Rouhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20Jabbari"> Masood Jabbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sima%20Honarmand"> Sima Honarmand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces a method to optimal design of a hybrid Wind/Photovoltaic/Fuel cell generation system for a typical domestic load that is not located near the electricity grid. In this configuration the combination of a battery, an electrolyser, and a hydrogen storage tank are used as the energy storage system. The aim of this design is minimization of overall cost of generation scheme over 20 years of operation. The Matlab/Simulink is applied for choosing the appropriate structure and the optimization of system sizing. A teaching learning based optimization is used to optimize the cost function. An overall power management strategy is designed for the proposed system to manage power flows among the different energy sources and the storage unit in the system. The results have been analyzed in terms of technics and economics. The simulation results indicate that the proposed hybrid system would be a feasible solution for stand-alone applications at remote locations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20energy%20system" title="hybrid energy system">hybrid energy system</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20sizing" title=" optimum sizing"> optimum sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20management" title=" power management"> power management</a>, <a href="https://publications.waset.org/abstracts/search?q=TLBO" title=" TLBO"> TLBO</a> </p> <a href="https://publications.waset.org/abstracts/35285/a-teaching-learning-based-optimization-for-optimal-design-of-a-hybrid-energy-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35285.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">578</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28244</span> Combustion Chamber Sizing for Energy Recovery from Furnace Process Gas: Waste to Energy </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Balram%20Panjwani">Balram Panjwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernd%20Wittgens"> Bernd Wittgens</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Erik%20Olsen"> Jan Erik Olsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Stein%20Tore%20Johansen"> Stein Tore Johansen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Norwegian ferroalloy industry is a world leader in sustainable production of ferrosilicon, silicon and manganese alloys with the lowest global specific energy consumption. One of the byproducts during the metal reduction process is energy rich off-gas and usually this energy is not harnessed. A novel concept for sustainable energy recovery from ferroalloy off-gas is discussed. The concept is founded on the idea of introducing a combustion chamber in the off-gas section in which energy rich off-gas mainly consisting of CO will be combusted. This will provide an additional degree of freedom for optimizing energy recovery. A well-controlled and high off-gas temperature will assure a significant increase in energy recovery and reduction of emissions to the atmosphere. Design and operation of the combustion chamber depend on many parameters, including the total power capacity of the combustion chamber, sufficient residence time for combusting the complex Poly Aromatic Hydrocarbon (PAH), NOx, as well as converting other potential pollutants. The design criteria for the combustion chamber have been identified and discussed and sizing of the combustion chamber has been carried out considering these design criteria. Computational Fluid Dynamics (CFD) has been utilized extensively for sizing the combustion chamber. The results from our CFD simulations of the flow in the combustion chamber and exploring different off-gas fuel composition are presented. In brief, the paper covers all aspect which impacts the sizing of the combustion chamber, including insulation thickness, choice of insulating material, heat transfer through extended surfaces, multi-staging and secondary air injection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20chamber" title=" combustion chamber"> combustion chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20furnace" title=" arc furnace"> arc furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20recovery" title=" energy recovery"> energy recovery</a> </p> <a href="https://publications.waset.org/abstracts/33818/combustion-chamber-sizing-for-energy-recovery-from-furnace-process-gas-waste-to-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33818.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">319</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28243</span> Developing Structured Sizing Systems for Manufacturing Ready-Made Garments of Indian Females Using Decision Tree-Based Data Mining</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hina%20Kausher">Hina Kausher</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangita%20Srivastava"> Sangita Srivastava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In India, there is a lack of standard, systematic sizing approach for producing readymade garments. Garments manufacturing companies use their own created size tables by modifying international sizing charts of ready-made garments. The purpose of this study is to tabulate the anthropometric data which covers the variety of figure proportions in both height and girth. 3,000 data has been collected by an anthropometric survey undertaken over females between the ages of 16 to 80 years from some states of India to produce the sizing system suitable for clothing manufacture and retailing. This data is used for the statistical analysis of body measurements, the formulation of sizing systems and body measurements tables. Factor analysis technique is used to filter the control body dimensions from a large number of variables. Decision tree-based data mining is used to cluster the data. The standard and structured sizing system can facilitate pattern grading and garment production. Moreover, it can exceed buying ratios and upgrade size allocations to retail segments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropometric%20data" title="anthropometric data">anthropometric data</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20tree" title=" decision tree"> decision tree</a>, <a href="https://publications.waset.org/abstracts/search?q=garments%20manufacturing" title=" garments manufacturing"> garments manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=sizing%20systems" title=" sizing systems"> sizing systems</a>, <a href="https://publications.waset.org/abstracts/search?q=ready-made%20garments" title=" ready-made garments"> ready-made garments</a> </p> <a href="https://publications.waset.org/abstracts/108349/developing-structured-sizing-systems-for-manufacturing-ready-made-garments-of-indian-females-using-decision-tree-based-data-mining" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108349.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">133</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28242</span> Technical and Practical Aspects of Sizing a Autonomous PV System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelhak%20Bouchakour">Abdelhak Bouchakour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Brahami"> Mustafa Brahami</a>, <a href="https://publications.waset.org/abstracts/search?q=Layachi%20Zaghba"> Layachi Zaghba </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of photovoltaic energy offers an inexhaustible supply of energy but also a clean and non-polluting energy, which is a definite advantage.

Our approach of optimization is basing on mathematical models, which amongst other things describe the operation of each part of the installation, the energy production, the storage and the consumption of energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20panel" title="solar panel">solar panel</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20radiation" title=" solar radiation"> solar radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=inverter" title=" inverter"> inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/33647/technical-and-practical-aspects-of-sizing-a-autonomous-pv-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33647.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">608</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28241</span> Optimal Placement and Sizing of Energy Storage System in Distribution Network with Photovoltaic Based Distributed Generation Using Improved Firefly Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ling%20Ai%20Wong">Ling Ai Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussain%20Shareef"> Hussain Shareef</a>, <a href="https://publications.waset.org/abstracts/search?q=Azah%20Mohamed"> Azah Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Asrul%20Ibrahim"> Ahmad Asrul Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The installation of photovoltaic based distributed generation (PVDG) in active distribution system can lead to voltage fluctuation due to the intermittent and unpredictable PVDG output power.

In this report, a detailed analysis of the energy efficiency of an electric distribution system was carried out with an implementation of the optimal capacitor placement and sizing (OCPS). The particle swarm optimization (PSO) will be used to determine optimal location and sizing for the capacitors whereas energy consumption and power losses minimization will improve the energy efficiency. In addition, a certain number of busbars or locations are identified in advance before the PSO is performed to solve OCPS. In this case study, three techniques are performed for the pre-selection of busbar or locations which are the power-loss-index (PLI). The particle swarm optimization (PSO) is designed to provide a new population with improved sizing and location of capacitors. The total cost of power losses, energy consumption and capacitor installation are the components considered in the objective and fitness functions of the proposed optimization technique. Voltage magnitude limit, total harmonic distortion (THD) limit, power factor limit and capacitor size limit are the parameters considered as the constraints for the proposed of optimization technique. In this research, the proposed methodologies implemented in the MATLAB® software will transfer the information, execute the three-phase unbalanced load flow solution and retrieve then collect the results or data from the three-phase unbalanced electrical distribution systems modeled in the SIMULINK® software. Effectiveness of the proposed methods used to improve the energy efficiency has been verified through several case studies and the results are obtained from the test systems of IEEE 13-bus unbalanced electrical distribution system and also the practical electrical distribution system model of Sultan Salahuddin Abdul Aziz Shah (SSAAS) government building in Shah Alam, Selangor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title="particle swarm optimization">particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-determine%20of%20capacitor%20locations" title=" pre-determine of capacitor locations"> pre-determine of capacitor locations</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20capacitors%20placement%20and%20sizing" title=" optimal capacitors placement and sizing"> optimal capacitors placement and sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced%20electrical%20distribution%20system" title=" unbalanced electrical distribution system"> unbalanced electrical distribution system</a> </p> <a href="https://publications.waset.org/abstracts/46202/optimal-capacitors-placement-and-sizing-improvement-based-on-voltage-reduction-for-energy-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46202.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">434</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28239</span> Assessment of Solar Hydrogen Production in Energetic Hybrid PV-PEMFC System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Rezzouk">H.

The system is composed of a photovoltaic array, a fuel cell, an electrolyzer and a hydrogen tank. HOMER software is used in this study to calculate the optimum capacities of the power system components that their combination allows an efficient use of solar resource to cover the hourly load needs. The optimal system sizing allows establishing the right balance between the daily electrical energy produced by the power system and the daily electrical energy consumed by the DC load using a 28 KW PV array, a 7.5 KW fuel cell, a 40KW electrolyzer and a 270 Kg hydrogen tank. The variation of powers involved into the DC bus of the hybrid PV-fuel cell system has been computed and analyzed for each hour over one year: the output powers of the PV array and the fuel cell, the input power of the elctrolyzer system and the DC primary load. Equally, the annual variation of stored hydrogen produced by the electrolyzer has been assessed. The PV array contributes in the power system with 82% whereas the fuel cell produces 18%. 38% of the total energy consumption belongs to the DC primary load while the rest goes to the electrolyzer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrolyzer" title="electrolyzer">electrolyzer</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20fueled%20cell" title=" hydrogen fueled cell"> hydrogen fueled cell</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a> </p> <a href="https://publications.waset.org/abstracts/12766/assessment-of-solar-hydrogen-production-in-energetic-hybrid-pv-pemfc-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12766.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">492</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28238</span> Systematic Approach for Energy-Supply-Orientated Production Planning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Keller">F.

In such kinds of resource (energy) intensive activities, energy analysis of the production system and looking for other alternatives which can reduce energy inputs of the sugarcane production process are steps forward for resource management. The purpose of this study was to determine input energy (direct and indirect) per hectare of sugarcane production sector of Metehara sugar factory in Ethiopia. Total energy consumption of the production system was 61,642 MJ/ha-yr. This total input energy is a cumulative value of different inputs (direct and indirect inputs) in the production system. The contribution of these different inputs is discussed and a scenario of substituting the most influential input by other alternative input which can replace the original input in its nutrient content was discussed. In this study the most influential input for increased energy consumption was application of organic fertilizer which accounted for 50 % of the total energy consumption. Filter cake which is a residue from the sugar production in the factory was used to substitute the organic fertilizer and the reduction in the energy consumption of the sugarcane production was discussed <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20analysis" title="energy analysis">energy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20fertilizer" title=" organic fertilizer"> organic fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20management" title=" resource management"> resource management</a>, <a href="https://publications.waset.org/abstracts/search?q=sugarcane" title=" sugarcane"> sugarcane</a> </p> <a href="https://publications.waset.org/abstracts/112638/energy-analysis-of-sugarcane-production-a-case-study-in-metehara-sugar-factory-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112638.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28236</span> Sizing Residential Solar Power Systems Based on Site-Specific Energy Statistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Arechavaleta">Maria Arechavaleta</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Halpin"> Mark Halpin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the United States, costs of solar energy systems have declined to the point that they are viable options for most consumers. However, there are no consistent procedures for specifying sufficient systems. The factors that must be considered are energy consumption, potential solar energy production, and cost. The traditional method of specifying solar energy systems is based on assumed daily levels of available solar energy and average amounts of daily energy consumption. The mismatches between energy production and consumption are usually mitigated using battery energy storage systems, and energy use is curtailed when necessary. The main consumer decision question that drives the total system cost is how much unserved (or curtailed) energy is acceptable? Of course additional solar conversion equipment can be installed to provide greater peak energy production and extra energy storage capability can be added to mitigate longer lasting low solar energy production periods. Each option increases total cost and provides a benefit which is difficult to quantify accurately. An approach to quantify the cost-benefit of adding additional resources, either production or storage or both, based on the statistical concepts of loss-of-energy probability and expected unserved energy, is presented in this paper. Relatively simple calculations, based on site-specific energy availability and consumption data, can be used to show the value of each additional increment of production or storage. With this incremental benefit-cost information, consumers can select the best overall performance combination for their application at a cost they are comfortable paying. The approach is based on a statistical analysis of energy consumption and production characteristics over time. The characteristics are in the forms of curves with each point on the curve representing an energy consumption or production value over a period of time; a one-minute period is used for the work in this paper. These curves are measured at the consumer location under the conditions that exist at the site and the duration of the measurements is a minimum of one week. While greater accuracy could be obtained with longer recording periods, the examples in this paper are based on a single week for demonstration purposes. The weekly consumption and production curves are overlaid on each other and the mismatches are used to size the battery energy storage system. Loss-of-energy probability and expected unserved energy indices are calculated in addition to the total system cost. These indices allow the consumer to recognize and quantify the benefit (probably a reduction in energy consumption curtailment) available for a given increase in cost. Consumers can then make informed decisions that are accurate for their location and conditions and which are consistent with their available funds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20energy%20storage%20systems" title="battery energy storage systems">battery energy storage systems</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20of%20load%20probability" title=" loss of load probability"> loss of load probability</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20renewable%20energy" title=" residential renewable energy"> residential renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy%20systems" title=" solar energy systems"> solar energy systems</a> </p> <a href="https://publications.waset.org/abstracts/50593/sizing-residential-solar-power-systems-based-on-site-specific-energy-statistics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50593.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28235</span> Feasibility Study and Developing Appropriate Hybrid Energy Systems in Regional Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Rouhani">Ahmad Rouhani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Iran has several potentials for using renewable energies, so use them could significantly contribute to energy supply.

Prime mover sizing is examined using three criteria: operational cost, carbon dioxide emissions (CDE), and primary energy consumption (PEC). The sizing process leads to consider ratios of conversion factors applied to imported electricity to conversion factors applied to fuel consumed. These ratios are labelled RCost, R CDE, R PEC depending on whether the conversion factors are associated with operational cost, CDE, or PEC, respectively. Analytical results show that in order to achieve savings in operational cost, CDE, or PEC, the ratios must be larger than a unique constant R Min that only depends on the CHP components efficiencies. Savings in operational cost, CDE, or PEC due to CHP operation are explicitly formulated using simple equations. This facilitates the process of comparing the tradeoffs of optimizing the savings of one criterion over the other two – a task that has traditionally been accomplished through computer simulations. A hospital building, located in Chlef, Algeria, was used as an example to apply the methodology presented in this article. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sizing" title="sizing">sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=heating%20and%20power" title=" heating and power"> heating and power</a>, <a href="https://publications.waset.org/abstracts/search?q=ratios" title=" ratios"> ratios</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20emissions" title=" carbon dioxide emissions"> carbon dioxide emissions</a> </p> <a href="https://publications.waset.org/abstracts/14685/prime-mover-sizing-for-base-loaded-combined-heating-and-power-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14685.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">231</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28233</span> Optimization and Feasibility Analysis of a PV/Wind/ Battery Hybrid Energy Conversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Doaa%20M.%20Atia">Doaa M.

Hybrid Optimization Model for Electric Renewable (HOMER) software program, which is developed by U.S National Renewable Energy Laboratory (NREL), is used for analyzing the feasibility of the stand-alone and hybrid system in this study. HOMER program determines whether renewable energy resources satisfy hourly electric demand or not. The program calculates energy balance for every 8760 hours in a year to simulate operation of the system. This optimization compares the demand for the electrical energy for each hour of the year with the energy supplied by the system for that hour and calculates the relevant energy flow for each component in the model. The essential principle is to minimize the total system cost while HOMER ensures control of the system. Moreover the feasibility analysis of the energy system is also studied. Wind speed, solar irradiance, interest rate and capacity shortage are the parameters which are taken into consideration. The simulation results indicate that the hybrid system is the best choice in this study, yielding lower net present cost. Thus, it provides higher system performance than PV or wind stand-alone systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20stand-alone%20system" title="wind stand-alone system">wind stand-alone system</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20stand-alone%20system" title=" photovoltaic stand-alone system"> photovoltaic stand-alone system</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20system" title=" hybrid system"> hybrid system</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20system%20sizing" title=" optimum system sizing"> optimum system sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=feasibility" title=" feasibility"> feasibility</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20analysis" title=" cost analysis"> cost analysis</a> </p> <a href="https://publications.waset.org/abstracts/3912/optimization-and-feasibility-analysis-of-a-pvwind-battery-hybrid-energy-conversion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3912.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">340</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28232</span> Application of Homer Optimization to Investigate the Prospects of Hybrid Renewable Energy System in Rural Area: Case of Rwanda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emile%20Niringiyimana">Emile Niringiyimana</a>, <a href="https://publications.waset.org/abstracts/search?q=LI%20Ji%20Qing"> LI Ji Qing</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Dushimimana"> Giovanni Dushimimana</a>, <a href="https://publications.waset.org/abstracts/search?q=Virginie%20Umwere"> Virginie Umwere</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development and utilization of renewable energy (RE) can not only effectively reduce carbon dioxide (CO2) emissions, but also became a solution to electricity shortage mitigation in rural areas.

In order to establish the optimal size of a RE system with adequate sizing of system components, electricity demand, solar radiation, hydrology, climate data are utilized as system input. The average daily solar radiation in Rukarara is 5.6 kWh/m2 and average wind speed is 3.5 m/s. The ideal integrated RE system, according to Homer optimization, consists of 91.21kW PV, 146kW hydropower, 12 x 24V li-ion batteries with a 20kW converter. The method of enhancing such hybrid systems control, sizing and choice of components is to reduce the Net present cost (NPC) of the system, unmet load, the cost of energy and reduction of CO2. The power consumption varies according to dominant source of energy in the system by controlling the energy compensation depending on the generation capacity of each power source. The initial investment of the RE system is $977,689.25, and its operation and maintenance expenses is $142,769.39 over a 25-year period. Although the investment is very high, the targeted profits in future are huge, taking into consideration of high investment in rural electrification structure implementations, tied with an increase of electricity cost and the 5 years payback period. The study outcomes suggest that the standalone hybrid PV-Hydropower system is feasible with zero pollution in Rukara community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HOMER%20optimization" title="HOMER optimization">HOMER optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20power%20system" title=" hybrid power system"> hybrid power system</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=NPC%20and%20solar%20pv%20systems" title=" NPC and solar pv systems"> NPC and solar pv systems</a> </p> <a href="https://publications.waset.org/abstracts/178977/application-of-homer-optimization-to-investigate-the-prospects-of-hybrid-renewable-energy-system-in-rural-area-case-of-rwanda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178977.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">61</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28231</span> Overview of Different Approaches Used in Optimal Operation Control of Hybrid Renewable Energy Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Kusakana">K. Kusakana </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A hybrid energy system is a combination of renewable energy sources with back up, as well as a storage system used to respond to given load energy requirements. Given that the electrical output of each renewable source is fluctuating with changes in weather conditions, and since the load demand also varies with time; one of the main attributes of hybrid systems is to be able to respond to the load demand at any time by optimally controlling each energy source, storage and back-up system. The induced optimization problem is to compute the optimal operation control of the system with the aim of minimizing operation costs while efficiently and reliably responding to the load energy requirement. Current optimization research and development on hybrid systems are mainly focusing on the sizing aspect. Thus, the aim of this paper is to report on the state-of-the-art of optimal operation control of hybrid renewable energy systems. This paper also discusses different challenges encountered, as well as future developments that can help in improving the optimal operation control of hybrid renewable energy systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renewable%20energies" title="renewable energies">renewable energies</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20systems" title=" hybrid systems"> hybrid systems</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=operation%20control" title=" operation control"> operation control</a> </p> <a href="https://publications.waset.org/abstracts/48787/overview-of-different-approaches-used-in-optimal-operation-control-of-hybrid-renewable-energy-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48787.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">379</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28230</span> Comprehensive Assessment of Energy Efficiency within the Production Process </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Kreitlein">S.

In assembly lines the workload on stations is different from each other due to different tasks times and the difference in workloads between stations can cause blockage or starvation in some stations in assembly lines. Buffers are used to store the semi-finished parts between the stations and can help to smooth the assembly production. The assembly line balancing and buffer sizing problem can affect the throughput of the assembly lines. Assembly line balancing and buffer sizing problems have been studied separately in literature and due to their collective contribution in throughput rate of assembly lines, balancing and buffer sizing problem are desired to study simultaneously and therefore they are considered concurrently in current research. Current research is aimed to maximize throughput, minimize total size of buffers in assembly line and minimize workload variations in assembly line simultaneously. A multi objective optimization objective is designed which can give better Pareto solutions from the Pareto front and a simple example problem is solved for assembly line balancing and buffer sizing simultaneously. Current research is significant for assembly line balancing research and it can be significant to introduce optimization approaches which can optimize current multi objective problem in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly%20line%20balancing" title="assembly line balancing">assembly line balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20sizing" title=" buffer sizing"> buffer sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=Pareto%20solutions" title=" Pareto solutions "> Pareto solutions </a> </p> <a href="https://publications.waset.org/abstracts/14084/multi-objective-simultaneous-assembly-line-balancing-and-buffer-sizing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14084.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">491</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28228</span> Evaluation of an Air Energy Recovery System in Greenhouse Fed by an Axial Air Extractor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eugueni%20Romantchik">Eugueni Romantchik</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilbero%20Lopez"> Gilbero Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Terrazas"> Diego Terrazas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The residual wind energy recovery from axial air extractors in greenhouses represents a constant source of clean energy production, which reduces production costs by reducing energy consumption costs. The objective of this work is to design, build and evaluate a residual wind energy recovery system. This system consists of a wind turbine placed at an optimal distance, a cone in the air discharge and a mechanism to vary the blades angle of the wind turbine. The system energy balance was analyzed, measuring the main energy parameters such as voltage, amperage, air velocities and angular speeds of the rotors. Tests were carried in a greenhouse with extractor Multifan 130 (1.2 kW, 550 rpm and 1.3 m of diameter) without cone and with cone, with the wind turbine (3 blades with 1.2 m in diameter). The implementation of the system allowed recovering up to 55% of the motor's energy. With the cone installed, the electric energy recovered was increased by 10%. Experimentally, it was shown that changing in 3 degrees the original angle of the wind turbine blades, the angular velocity increases 17.7%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20energy" title="air energy">air energy</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust%20fan" title=" exhaust fan"> exhaust fan</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse" title=" greenhouse"> greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title=" wind turbine"> wind turbine</a> </p> <a href="https://publications.waset.org/abstracts/105900/evaluation-of-an-air-energy-recovery-system-in-greenhouse-fed-by-an-axial-air-extractor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105900.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28227</span> Energy Efficiency Analysis of Electrical Submersible Pump on Mature Oil Field Offshore Java Sea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marda%20Vidrianto">Marda Vidrianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Tania%20Surya%20Utami"> Tania Surya Utami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrical Submersible Pump (ESP) is an artificial lift of choice to produce oil on Offshore Java Sea. It is selected based on the production rate capacity and running life expectation. ESP performance in a mature field is highly affected by oil well conditions. The presence of sand, scale, gas, and low influx will create unstable ESP operation hence lowering the run life expectation and system efficiency. This paper reviews the current energy usage and efficiency on every part of the ESP system. The hydraulic and electrical losses, as well as system efficiency for each well, are calculated to identify energy losses and the possibility for improvement. It is shown that high back pressure on the system and low-efficiency pump are the major contributors to energy losses. It was found that optimized production rate and the use of advanced technology on pump and motor unit could improve energy efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=advance%20technology" title="advance technology">advance technology</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=ESP" title=" ESP"> ESP</a>, <a href="https://publications.waset.org/abstracts/search?q=mature%20field" title=" mature field"> mature field</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20rate" title=" production rate"> production rate</a> </p> <a href="https://publications.waset.org/abstracts/93119/energy-efficiency-analysis-of-electrical-submersible-pump-on-mature-oil-field-offshore-java-sea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93119.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28226</span> Comparison of Irradiance Decomposition and Energy Production Methods in a Solar Photovoltaic System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tisciane%20Perpetuo%20e%20Oliveira">Tisciane Perpetuo e Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Dante%20Inga%20Narvaez"> Dante Inga Narvaez</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Gradella%20Villalva"> Marcelo Gradella Villalva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Installations of solar photovoltaic systems have increased considerably in the last decade. Therefore, it has been noticed that monitoring of meteorological data (solar irradiance, air temperature, wind velocity, etc.) is important to predict the potential of a given geographical area in solar energy production. In this sense, the present work compares two computational tools that are capable of estimating the energy generation of a photovoltaic system through correlation analyzes of solar radiation data: PVsyst software and an algorithm based on the PVlib package implemented in MATLAB. In order to achieve the objective, it was necessary to obtain solar radiation data (measured and from a solarimetric database), analyze the decomposition of global solar irradiance in direct normal and horizontal diffuse components, as well as analyze the modeling of the devices of a photovoltaic system (solar modules and inverters) for energy production calculations. Simulated results were compared with experimental data in order to evaluate the performance of the studied methods. Errors in estimation of energy production were less than 30% for the MATLAB algorithm and less than 20% for the PVsyst software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20production" title="energy production">energy production</a>, <a href="https://publications.waset.org/abstracts/search?q=meteorological%20data" title=" meteorological data"> meteorological data</a>, <a href="https://publications.waset.org/abstracts/search?q=irradiance%20decomposition" title=" irradiance decomposition"> irradiance decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20photovoltaic%20system" title=" solar photovoltaic system"> solar photovoltaic system</a> </p> <a href="https://publications.waset.org/abstracts/101500/comparison-of-irradiance-decomposition-and-energy-production-methods-in-a-solar-photovoltaic-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101500.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28225</span> Energy Consumption in Biodiesel Production at Various Kinetic Reaction of Transesterification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sariah%20Abang">Sariah Abang</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20M.%20Anisuzzaman"> S.

The challenge of its commercialization is associated with high production cost due to its feedstock also useful in various food products. Non-competitive feedstock such as waste cooking oils normally contains a large amount of free fatty acids (FFAs). Large amount of fatty acid degrades the alkaline catalyst in the biodiesel production, thereby decreasing the biodiesel production rate. Generally, biodiesel production processes including esterification and trans-esterification are conducting in a mixed system, in which the hydrodynamic effect on the reaction could not be completely defined. The aim of this study was to investigate the effect of variation rate constant and activation energy on energy consumption of biodiesel production. Usually, the changes of rate constant and activation energy depend on the operating temperature and the degradation of catalyst. By varying the activation energy and kinetic rate constant, the effects can be seen on the energy consumption of biodiesel production. The result showed that the energy consumption of biodiesel is dependent on the changes of rate constant and activation energy. Furthermore, this study was simulated using Aspen HYSYS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methanol" title="methanol">methanol</a>, <a href="https://publications.waset.org/abstracts/search?q=palm%20oil" title=" palm oil"> palm oil</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=transesterification" title=" transesterification"> transesterification</a>, <a href="https://publications.waset.org/abstracts/search?q=triolein" title=" triolein"> triolein</a> </p> <a href="https://publications.waset.org/abstracts/66326/energy-consumption-in-biodiesel-production-at-various-kinetic-reaction-of-transesterification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66326.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28224</span> A Mathematical Programming Model for Lot Sizing and Production Planning in Multi-Product Companies: A Case Study of Azar Battery Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Jafarpour%20Taher">Farzad Jafarpour Taher</a>, <a href="https://publications.waset.org/abstracts/search?q=Maghsud%20Solimanpur"> Maghsud Solimanpur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Production planning is one of the complex tasks in multi-product firms that produce a wide range of products. Since resources in mass production companies are limited and different products use common resources, there must be a careful plan so that firms can respond to customer needs efficiently. Azar-battery Company is a firm that provides twenty types of products for its customers. Therefore, careful planning must be performed in this company. In this research, the current conditions of Azar-battery Company were investigated to provide a mathematical programming model to determine the optimum production rate of the products in this company. The production system of this company is multi-stage, multi-product and multi-period. This system is studied in terms of a one-year planning horizon regarding the capacity of machines and warehouse space limitation. The problem has been modeled as a linear programming model with deterministic demand in which shortage is not allowed. The objective function of this model is to minimize costs (including raw materials, assembly stage, energy costs, packaging, and holding). Finally, this model has been solved by Lingo software using the branch and bound approach. Since the computation time was very long, the solver interrupted, and the obtained feasible solution was used for comparison. The proposed model's solution costs have been compared to the company’s real data. This non-optimal solution reduces the total production costs of the company by about %35. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-period" title="multi-period">multi-period</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-product%20production" title=" multi-product production"> multi-product production</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-stage" title=" multi-stage"> multi-stage</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20planning" title=" production planning"> production planning</a> </p> <a href="https://publications.waset.org/abstracts/174173/a-mathematical-programming-model-for-lot-sizing-and-production-planning-in-multi-product-companies-a-case-study-of-azar-battery-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174173.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28223</span> Contribution to Energy Management in Hybrid Energy Systems Based on Agents Coordination</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Saba">Djamel Saba</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zohra%20Laallam"> Fatima Zohra Laallam</a>, <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Berbaoui"> Brahim Berbaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a contribution to the design of a multi-agent for the energy management system in a hybrid energy system (SEH).

The data in this study were collected from tomato farms in Bursa province, Karacabey and Mustafakemalpasa district. Questionnaires were administered through face-to-face interview in 2011-2012. The results of the study show that diesel have the highest rate of energy equivalency of all the inputs used in tomato production at 60,07%. The energy equivalent rate of electricity is 4,26% and the energy equivalent rate of water is 0,87%. The energy equivalent rates for human power, machinery, chemicals and water for irrigation were determined to be low in tomato production. According to the output/input ratio calculated, the energy ratio is 1,50 in tomato production in the research area. This ratio implies that the inputs used in tomato production have not been used effectively. Ineffective use of these resources also causes environmental problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomato%20production" title="Tomato production">Tomato production</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20ratio" title=" energy ratio"> energy ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20input" title=" energy input"> energy input</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/96601/an-analysis-of-energy-use-and-input-level-for-tomato-production-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96601.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">232</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28221</span> Design of a Solar Water Heating System with Thermal Storage for a Three-Bedroom House in Newfoundland </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Aisa">Ahmed Aisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Iqbal"> Tariq Iqbal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This letter talks about the ready-to-use design of a solar water heating system because, in Canada, the average consumption of hot water per person is approximately 50 to 75 L per day and the average Canadian household uses 225 L. Therefore, this paper will demonstrate the method of designing a solar water heating system with thermal storage. It highlights the renewable hybrid power system, allowing you to obtain a reliable, independent system with the optimization of the ingredient size and at an improved capital cost. The system can provide hot water for a big building. The main power for the system comes from solar panels. Solar Advisory Model (SAM) and HOMER are used. HOMER and SAM are design models that calculate the consumption of hot water and cost for a house. Some results, obtained through simulation, were for monthly energy production, annual energy production, after tax cash flow, the lifetime of the system and monthly energy usage represented by three types of energy. These are system energy, electricity load electricity and net metering credit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20heating" title="water heating">water heating</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20storage" title=" thermal storage"> thermal storage</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20cost%20solar" title=" capital cost solar"> capital cost solar</a>, <a href="https://publications.waset.org/abstracts/search?q=consumption" title=" consumption"> consumption</a> </p> <a href="https://publications.waset.org/abstracts/50580/design-of-a-solar-water-heating-system-with-thermal-storage-for-a-three-bedroom-house-in-newfoundland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28220</span> Maximaxing the Usage of Solar Energy in an Area of Low Peak Sunlight Hours</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ohabuiro%20John%20Uwabunkeonye">Ohabuiro John Uwabunkeonye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Source of green energy is becoming a concern in developing countries where most energy source in use emits high level of carbon (IV) oxide which contributes to global warming. More so, even with the generation of energy from fossil fuel, the electricity supply is still very inadequate. Therefore, this paper examines different ways of designing and installing photovoltaic (PV) system in terms of optimal sizing of PV array and battery storage in an area of very low peak sunlight hours (PSH) and inadequate supply of electricity from utility companies. Different sample of Peak sunlight hour for selected areas in Nigeria are considered and the lowest of it all is taken. Some means of ensuring that the available solar energy is harnessed properly and converted into electrical energy are discussed for usage in such areas as mentioned above. <p
