class="card-text"><strong>Abstract:</strong></p> Dynamic Thermal Rating (DTR) provides crucial information by estimating the ampacity of transmission lines to improve power dispatching efficiency. To perform the DTR, it is necessary to install on-line thermal sensors to monitor conductor temperature and weather variables. A simple and intuitive strategy is to allocate a thermal sensor to every span of transmission lines, but the cost of sensors might be too high to bear. To deal with the cost issue, a thermal sensor placement problem must be solved. This research proposes and implements a hybrid algorithm which combines proper orthogonal decomposition (POD) with particle swarm optimization (PSO) methods. The proposed hybrid algorithm solves a multi-objective optimization problem that concludes the minimum number of sensors and the minimum error on conductor temperature, and the optimal sensor placement is determined simultaneously. The data of 345 kV transmission lines and the hourly weather data from the Taiwan Power Company and Central Weather Bureau (CWB), respectively, are used by the proposed method. The simulated results indicate that the number of sensors could be reduced using the optimal placement method proposed by the study and an acceptable error on conductor temperature could be achieved. This study provides power companies with a reliable reference for efficiently monitoring and managing their power grids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20thermal%20rating" title="dynamic thermal rating">dynamic thermal rating</a>, <a href="https://publications.waset.org/abstracts/search?q=proper%20orthogonal%20decomposition" title=" proper orthogonal decomposition"> proper orthogonal decomposition</a>, <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=sensor%20placement" title=" sensor placement"> sensor placement</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grid" title=" smart grid"> smart grid</a> </p> <a href="https://publications.waset.org/abstracts/63744/application-of-particle-swarm-optimization-to-thermal-sensor-placement-for-smart-grid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63744.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">432</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">10040</span> A Strategy of Direct Power Control for PWM Rectifier Reducing Ripple in Instantaneous Power</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Mohammed%20Chikouche">T.

This control method is applied to overcome the instantaneous power ripple, to eliminate line current harmonics and therefore reduce the total harmonic distortion and to improve the power factor. A switching table is based on the analysis on the change of instantaneous active and reactive power, to select the optimum switching state of the three-phase PWM rectifier.

The main TCAM-design challenge is to decrease the power consumption associated with the large amount of parallel active circuitry, without compromising with speed or memory density. Furthermore, when the channel length decreases, leakage power becomes more significant, and it can even dominate dynamic power at lower technologies. In this paper, we propose a TCAM-design technique, called Virtual Power Supply technique that reduces the leakage by a substantial amount. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=match%20line%20%28ML%29" title="match line (ML)">match line (ML)</a>, <a href="https://publications.waset.org/abstracts/search?q=search%20line%20%28SL%29" title=" search line (SL)"> search line (SL)</a>, <a href="https://publications.waset.org/abstracts/search?q=ternary%20content%20addressable%20memory%20%28TCAM%29" title=" ternary content addressable memory (TCAM)"> ternary content addressable memory (TCAM)</a>, <a href="https://publications.waset.org/abstracts/search?q=Leakage%20power%20%28LP%29" title=" Leakage power (LP)"> Leakage power (LP)</a> </p> <a href="https://publications.waset.org/abstracts/52223/ternary-content-addressable-memory-cell-with-a-leakage-reduction-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52223.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">299</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">10038</span> Estimate of Maximum Expected Intensity of One-Half-Wave Lines Dancing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Bekbaev">A.

This study present comparisons in terms of fuel consumption, power split, and state of charge (SoC) of an HEV containing an EVT to a conventional parallel topology and a series topology. To this end, corresponding simulations of these topologies are all performed in presence of control strategies enabling battery charge-sustaining and efficient power split. The power flow through the components of the vehicle are attained, and fuel consumption results of the considered cases are compared. The investigation of the results indicates utilizing EVT can provide significant added values in HEV configurations.

This brings about the critical need for coordinating power production and power exchange for different regions. As compared with the power-only systems, the combined heat and power (CHP) systems can provide additional flexibility of utilizing RES by exploiting the interdependence of power and heat production in the CHP plant. In the CHP system, power production can be influenced by adjusting heat production level and electric power can be used to satisfy heat demand by electric boiler or heat pump in conjunction with heat storage, which is much cheaper than electric storage. This paper addresses multi-site CHP systems without considering RES, which lay foundation for handling penetration of RES. The problem under study is the unit commitment (UC) of the transmission-constrained multi-site CHP systems. We solve the problem by combining linear relaxation of ON/OFF states and sequential dynamic programming (DP) techniques, where relaxed states are used to reduce the dimension of the UC problem and DP for improving the solution quality. Numerical results for daily scheduling with realistic models and data show that DP-based algorithm is from a few to a few hundred times faster than CPLEX (standard commercial optimization software) with good solution accuracy (less than 1% relative gap from the optimal solution on the average). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20programming" title="dynamic programming">dynamic programming</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-site%20combined%20heat%20and%20power%20system" title=" multi-site combined heat and power system"> multi-site combined heat and power system</a>, <a href="https://publications.waset.org/abstracts/search?q=relaxed%20states" title=" relaxed states"> relaxed states</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission-constrained%20generation%20unit%20commitment" title=" transmission-constrained generation unit commitment"> transmission-constrained generation unit commitment</a> </p> <a href="https://publications.waset.org/abstracts/48533/dynamic-programming-based-algorithm-for-the-unit-commitment-of-the-transmission-constrained-multi-site-combined-heat-and-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48533.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">365</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">10035</span> Technical and Economic Evaluation of Harmonic Mitigation from Offshore Wind Power Plants by Transmission Owners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Prajapati">A.

This paper outlines the findings of the study conducted to verify the proposal that the harmonic mitigation could be optimized and can be managed economically and effectively at the transmission network level by the Transmission Owner (TO) instead of the individual polluter connected to the grid. Harmonic mitigation studies were conducted on selected regions of the transmission network in England for recently connected offshore wind power plants to strategize and optimize selected harmonic filter options. The results – filter volume and capacity – were then compared against the mitigation measures adopted by the individual connections. Estimation ratios were developed based on the actual installed and optimal proposed filters. These estimation ratios were then used to derive harmonic filter requirements for future contracted connections. The study has concluded that a saving of 37% in the filter volume/capacity could be achieved if the TO is to centrally manage the harmonic mitigation instead of individual polluter installing their own mitigation solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C-type%20filter" title="C-type filter">C-type filter</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonics" title=" harmonics"> harmonics</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=offshore%20wind%20farms" title=" offshore wind farms"> offshore wind farms</a>, <a href="https://publications.waset.org/abstracts/search?q=interconnectors" title=" interconnectors"> interconnectors</a>, <a href="https://publications.waset.org/abstracts/search?q=HVDC" title=" HVDC"> HVDC</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=transmission%20owner" title=" transmission owner"> transmission owner</a> </p> <a href="https://publications.waset.org/abstracts/98379/technical-and-economic-evaluation-of-harmonic-mitigation-from-offshore-wind-power-plants-by-transmission-owners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98379.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">157</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">10034</span> The Mechanism of Design and Analysis Modeling of Performance of Variable Speed Wind Turbine and Dynamical Control of Wind Turbine Power</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Heydariazad">Mohammadreza Heydariazad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Productivity growth of wind energy as a clean source needed to achieve improved strategy in production and transmission and management of wind resources in order to increase quality of power and reduce costs.

Therefore, designing gears for minimum weight and maximum power transmission is the main target of this study. In this regard, a new approach has been developed to estimate the load share and stress distribution of worm gear sets. The approach is based upon considering the instantaneous tooth meshing stiffness where the worm gear drive was modelled as a series of spur gear slices, and each slice was analyzed separately using a well-established criteria. By combining the results obtained for all slices, the entire worm gear set loading and stressing was determined. The geometric modelling method presented, allows tooth elastic deformation and tooth root stresses of worm gear drives under different load conditions to be investigated. On the basis of the method introduced in this study, the instantaneous meshing stiffness and load share were obtained. In comparison with existing methods, this approach has both good analytical accuracy and less computing time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gear" title="gear">gear</a>, <a href="https://publications.waset.org/abstracts/search?q=load%2Fstress%20distribution" title=" load/stress distribution"> load/stress distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=worm" title=" worm"> worm</a>, <a href="https://publications.waset.org/abstracts/search?q=wheel" title=" wheel"> wheel</a>, <a href="https://publications.waset.org/abstracts/search?q=tooth%20stiffness" title=" tooth stiffness"> tooth stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20line" title=" contact line"> contact line</a> </p> <a href="https://publications.waset.org/abstracts/63727/design-improvement-of-worm-gearing-for-better-energy-utilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63727.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">422</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">10031</span> Optimal Capacitor Placement in Distribution Using Cuckoo Optimization Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ravangard">Ali Ravangard</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Mohammadi"> S.

They are utilized as sources of reactive power by connecting them in line-to-neutral. Electric utilities have also connected capacitors in series with long lines in order to reduce its impedance. This is particularly common in the transmission level, where the lines have length in several hundreds of kilometers. However, this post will generally discuss shunt capacitors. In distribution systems, shunt capacitors are used to reduce power losses, to improve voltage profile, and to increase the maximum flow through cables and transformers. This paper presents a new method to determine the optimal locations and economical sizing of fixed and/or switched shunt capacitors with a view to power losses reduction and voltage stability enhancement. For solving the problem, a new enhanced cuckoo optimization algorithm is presented.The proposed method is tested on distribution test system and the results show that the algorithm suitable for practical implementation on real systems with any size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitor%20placement" title="capacitor placement">capacitor placement</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20losses" title=" power losses"> power losses</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20stability" title=" voltage stability"> voltage stability</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20distribution%20systems" title=" radial distribution systems"> radial distribution systems</a> </p> <a href="https://publications.waset.org/abstracts/44037/optimal-capacitor-placement-in-distribution-using-cuckoo-optimization-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44037.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">377</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">10030</span> Transmission Design That Eliminates Gradual System Problems in Gearboxes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96mer%20Ate%C5%9F">Ömer Ateş</a>, <a href="https://publications.waset.org/abstracts/search?q=Atilla%20Sava%C5%9F"> Atilla Savaş</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reducers and transmission systems are power and speed transfer tools that have been used for many years in the technology world and in all engineering fields. Since today's transmissions have a threaded tap system, torque interruption occurs during tap change. besides, breakdown and manufacturing costs are high. Another problem is the limited torque and rpm setting in stepped gearbox systems. In this study, a new type of transmission system is designed to solve these problems. This new type of transmission system has been called the Continuously Variable Pulley. The most important feature of the transmission system in the study is that it can be adjusted Revolutions Per Minute-wise and torque-wise at the millimeter (precision) adjustment level. In order to make adjustments at this level, an adjustable pulley with the help of hydraulic piston is designed. The efficiency of the designed transmission system is 97 percent, the efficiency of today's transmissions is in the range of 85-95 percent. examined at the analysis and calculations, it is seen that the designed system gives realistic results and can be compared with today's transmissions and reducers. Therefore, this new type of transmission has been proven to be usable in production areas and the world of technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gearbox" title="gearbox">gearbox</a>, <a href="https://publications.waset.org/abstracts/search?q=reducer" title=" reducer"> reducer</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=torque" title=" torque"> torque</a> </p> <a href="https://publications.waset.org/abstracts/128464/transmission-design-that-eliminates-gradual-system-problems-in-gearboxes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128464.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">121</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">10029</span> Extremely Low-Frequency Magnetic Field; An Invisible Risk Association between High Power Transmission Lines and Childhood Leukemia and Adult Brain Cancer: Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Azeem">Ali Azeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Cheol%20Hong"> Seung-Cheol Hong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on the epidemiological association between childhood leukaemia & adult brain cancer to offer strong evidence that extremely low-frequency magnetic field (ELF-MF) produced from power lines caused cancer.

VSR integrates an on-load tap changer (OLTC) that adjusts reactive power compensation to maintain acceptable bus voltages under variable load profile and network configuration. An automatic voltage regulator (AVR) or a power management system (PMS) that allows VSR rating to be changed in discrete steps typically controls the OLTC. Typical regulation range start as minimum as 20% up to 100% and are available for systems up to 550kV. The regulation speed is normally in the order of seconds per step and approximately a minute from maximum to minimum rating. VSR can be bus or line connected depending on line/cable length and compensation requirements. The flexible reactive compensation ranges achieved by recent VSR technologies have enabled newer facilities design to deploy line connected VSR through either disconnect switches, which saves space and cost, or through circuit breakers. Lines with VSR are typically energized with lower taps (reduced reactive compensation) to minimize or remove the presence of delayed zero crossing. <p class="card-text"><strong>Keywords:</strong> <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=reactive%20power" title=" reactive power"> reactive power</a>, <a href="https://publications.waset.org/abstracts/search?q=subsea%20cables" title=" subsea cables"> subsea cables</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20shunt%20reactors" title=" variable shunt reactors"> variable shunt reactors</a> </p> <a href="https://publications.waset.org/abstracts/143206/variable-shunt-reactors-for-reactive-power-compensation-of-hv-subsea-cables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143206.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">252</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">10026</span> Enhancing the Stability of Vietnamese Power System - from Theory to Practical</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edwin%20Lerch">Edwin Lerch</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirk%20Audring"> Dirk Audring</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuong%20Nguyen%20Mau"> Cuong Nguyen Mau</a>, <a href="https://publications.waset.org/abstracts/search?q=Duc%20Ninh%20Nguyen"> Duc Ninh Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Cuong%20Nguyen"> The Cuong Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Van%20Nguyen"> The Van Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The National Load Dispatch Centre of Electricity Vietnam (EVNNLDC) and Siemens PTI investigated the stability of the electrical 500/220 kV transportation system of Vietnam. The general scope of the investigations is improving the stability of the Vietnam power system and giving the EVNNLDC staff the capability to decide how to deal with expected stability challenges in the future, which are related to the very fast growth of the system. Rapid system growth leads to a very high demand of power transmission from North to South. This was investigated by stability studies of interconnected power system with neighboring countries. These investigations are performed in close cooperation and coordination with the EVNNLDC project team. This important project includes data collection, measurement, model validation and investigation of relevant stability phenomena as well as training of the EVNNLDC staff. Generally, the power system of Vietnam has good voltage and dynamic stability. The main problems are related to the longitudinal system with more power generation in the North and Center, especially hydro power, and load centers in the South of Vietnam. Faults on the power transmission system from North to South risks the stability of the entire system due to a high power transfer from North to South and high loading of the 500 kV backbone. An additional problem is the weak connection to Cambodia power system which leads to interarea oscillations mode. Therefore, strengthening the power transfer capability by new 500kV lines or HVDC connection and balancing the power generation across the country will solve many challenges. Other countermeasures, such as wide area load shedding, PSS tuning and correct SVC placement will improve and stabilize the power system as well. Primary frequency reserve should be increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20power%20transmission%20system%20studies" title="dynamic power transmission system studies">dynamic power transmission system studies</a>, <a href="https://publications.waset.org/abstracts/search?q=blackout%20prevention" title=" blackout prevention"> blackout prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20interconnection" title=" power system interconnection"> power system interconnection</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/58895/enhancing-the-stability-of-vietnamese-power-system-from-theory-to-practical" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58895.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">361</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">10025</span> Achievable Average Secrecy Rates over Bank of Parallel Independent Fading Channels with Friendly Jamming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munnujahan%20Ara">Munnujahan Ara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we investigate the effect of friendly jamming power allocation strategies on the achievable average secrecy rate over a bank of parallel fading wiretap channels.

This process has involved disaggregating former state-owned monopoly utilities both vertically and horizontally and introduced competition. The restructuring process has been implemented by the Australian National Electricity Market (NEM) started from 13 December 1998, began operating as a wholesale market for supply of electricity to retailers and end-users in Queensland, New South Wales, the Australian Capital Territory, Victoria and South Australia. In this deregulated market, one of the important issues is the transmission pricing. Transmission pricing is a service that recovers existing and new cost of the transmission system. The regulation of the transmission pricing is important in determining whether the transmission service system is economically beneficial to both side of the users and utilities. Therefore, an efficient transmission pricing methodology plays an important role in the Australian NEM. In this paper, the transmission pricing methodologies that have been implemented by the Australian NEM which are the Cost Reflective Network Pricing (CRNP) and Modified Cost Reflective Network Pricing (MCRNP) methods are investigated for allocating the transmission service charges to the transmission users. A case study using 6-bus system is used in order to identify the best method that reflects a fair and equitable transmission service charge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost-reflective%20network%20pricing%20method" title="cost-reflective network pricing method">cost-reflective network pricing method</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20cost-reflective%20network%20pricing%20method" title=" modified cost-reflective network pricing method"> modified cost-reflective network pricing method</a>, <a href="https://publications.waset.org/abstracts/search?q=restructuring%20process" title=" restructuring process"> restructuring process</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20pricing" title=" transmission pricing"> transmission pricing</a> </p> <a href="https://publications.waset.org/abstracts/62287/investigation-on-cost-reflective-network-pricing-and-modified-cost-reflective-network-pricing-methods-for-transmission-service-charges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62287.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">445</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">10023</span> The Batteryless Wi-Fi Backscatter System and Method for Improving the Transmission Range</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Min%20Ko">Young-Min Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Jun%20Yu"> Seung-Jun Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Seongjoo%20Lee"> Seongjoo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoung-Kyu%20Song"> Hyoung-Kyu Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Internet of things (IoT) system has attracted attention. IoT is a technology to connect all the objects to the internet as well as computer. IoT makes it possible for providing more data interoperability methods for an application purpose. Among the IoT technology, the research of devices so that they can communicate without power supply has been actively conducted. Batteryless system permits us to communicate without power supply devices. In this paper, batteryless backscatter system is used as a tag. And mobile devices which are embedded wireless fidelity (Wi-Fi) chipset are used as a reader. The backscatter tag can be obtained Internet connectivity from the reader.

In general, power saving is currently the nominal goal of most industrial countries. It is well known that fossil fuels are the main pillar of development of world countries. Unfortunately, the increased rate of fossil fuel consumption will lead to serious problems caused by an expected depletion of fuels. Moreover, dangerous gases and vapors emission lead to severe environmental problems during fuel burning. Consequently, most engineering sectors especially the mechanical sectors are looking for improving any machine accompanied by reducing its energy consumption. Crank-Rocker planar mechanism is the most applied in mechanical systems. Besides, it is one of the most significant parts of the machines for obtaining the oscillatory motion. The transmission angle of this mechanism can be considered as an optimum value when its extreme values are equally varied around 90°. In addition, the transmission angle plays an important role in decreasing the required driving power and improving the dynamic properties of the mechanism. Hence, appropriate selection of mechanism links lengthens, which assures optimum transmission angle leads to decreasing the driving power. Moreover, mechanism's links manufactured from composite materials afford link's lightweight, which decreases the required driving torque. Furthermore, wear and corrosion problems can be treated through using composite links instead of using metal ones. This paper is dealing with improving the performance of crank-rocker mechanism using composite links due to their flexural elastic modulus values and stiffness in addition to high damping of composite materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Composite%20Material" title="Composite Material">Composite Material</a>, <a href="https://publications.waset.org/abstracts/search?q=Crank-Rocker%20Mechanism" title=" Crank-Rocker Mechanism"> Crank-Rocker Mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=Transmission%20angle" title=" Transmission angle"> Transmission angle</a>, <a href="https://publications.waset.org/abstracts/search?q=Design%20techniques" title=" Design techniques"> Design techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=Power%20Saving" title=" Power Saving"> Power Saving</a> </p> <a href="https://publications.waset.org/abstracts/83042/power-and-wear-reduction-using-composite-links-of-crank-rocker-mechanism-with-optimum-transmission-angle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83042.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">304</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">10019</span> Comparison of Power Consumption of WiFi Inbuilt Internet of Things Device with Bluetooth Low Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Darshana%20Thomas">Darshana Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Wilkie"> Edward Wilkie</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Irvine"> James Irvine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Internet of things (IoT) is currently a highly researched topic, especially within the context of the smart home. These are small sensors that are capable of gathering data and transmitting it to a server. The majority of smart home products use protocols such as ZigBee or Bluetooth Low Energy (BLE). As these small sensors are increasing in number, the need to implement these with much more capable and ubiquitous transmission technology is necessary. The high power consumption is the reason that holds these small sensors back from using other protocols such as the most ubiquitous form of communication, WiFi. Comparing the power consumption of existing transmission technologies to one with WiFi inbuilt, would provide a better understanding for choosing between these technologies. We have developed a small IoT device with WiFi capability and proven that it is much more efficient than the first protocol, 433 MHz. We extend our work in this paper and compare WiFi power consumption with the other most widely used protocol BLE. The experimental results in this paper would conclude whether the developed prototype is capable in terms of power consumption to replace the existing protocol BLE with WiFi. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bluetooth" title="bluetooth">bluetooth</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things%20%28IoT%29" title=" internet of things (IoT)"> internet of things (IoT)</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20consumption" title=" power consumption"> power consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=WiFi" title=" WiFi"> WiFi</a> </p> <a href="https://publications.waset.org/abstracts/54389/comparison-of-power-consumption-of-wifi-inbuilt-internet-of-things-device-with-bluetooth-low-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54389.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">267</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">10018</span> Transient Stability Improvement in Multi-Machine System Using Power System Stabilizer (PSS) and Static Var Compensator (SVC)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khoshnaw%20Khalid%20Hama%20Saleh">Khoshnaw Khalid Hama Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ergun%20Ercelebi"> Ergun Ercelebi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasingly complex modern power systems require stability, especially for transient and small disturbances.

Dynamic modeling and analysis of such inter-tie, which is, proposed to transfer energy from west to south and vice versa will be demonstrated and discussed. The west-central-south inter-tie links Al-Aula-Zaba-Tabuk-Tubajal-Jawf-Hail. It is essential to investigate the transient over-voltage to assure steady and stable transmission over such inter-tie. Saudi Electricity Company (SEC) has been improving its grid to make the whole country as an interconnected system. Already east, central and west were interconnected, yet mostly each is fed with its local generation. The SEC is planning to establish many inter-ties to strengthen the transient stability of its grid. The paper studies one of the important links of 380 kV, 220 km between Tabouk and Tubarjal, which is a step towards connecting the West with the South region. Modeling and analysis using some softwares will be utilized under different scenarios. Adoption of methods to stabilize and increase its power transmission are also discussed. Improvement of power system transients has been controlled by FACTS elements such the Static Var Compensators (SVC) receiving a wide interest since many technical studies have proven their effects on damping system oscillations and stability enhancement. Illustrations of the transient at each main generating or load bus will be checked in all inter-tie links. A brief review of possible means to solve the transient over-voltage problem using different FACTS element modeling will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transient%20stability" title="transient stability">transient stability</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20var%20compensator" title=" static var compensator"> static var compensator</a>, <a href="https://publications.waset.org/abstracts/search?q=central-west%20interconnected%20system" title=" central-west interconnected system"> central-west interconnected system</a>, <a href="https://publications.waset.org/abstracts/search?q=damping%20controller" title=" damping controller"> damping controller</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Electricity%20Company" title=" Saudi Electricity Company"> Saudi Electricity Company</a> </p> <a href="https://publications.waset.org/abstracts/7181/preliminary-studies-of-transient-stability-for-the-380-kv-connection-west-central-of-saudi-electricity-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7181.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">609</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">10013</span> Investigating the Performance of Power Industry in a Developing Nation for Industrialization and Environmental Security</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abel%20Edeowede%20Abhulimen">Abel Edeowede Abhulimen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to supply irregularity and frequent outages, the need for reliability in power supply has grown unsatisfactorily over time in developing nations, impeding industrialization and fueling insecurity. This article attempts to break down the Nigerian power issue into its numerous sub-sectors in order to pinpoint the industry's ailment and suggest a viable fix. Monthly average performance data were obtained for the various sub-sectors across the industry for eight consecutive quarters. Whereas the amount of energy generated was found to be insufficient to engender industrialization in a nation like Nigeria, the transmission infrastructure was inadequate for the amount of power needed to be wheeled. Additionally, the distribution sub-sector was plagued with problems such as revenue collection inefficiency, severe enough to impede the growth of the entire industry. The country's goal of attaining energy sufficiency and industrialization would significantly be closer to reality with a conscious effort to increase the base of power generation through aggressive investment in Combined Cycle Gas Turbines (CCGT), decentralization of the transmission infrastructure, and strict monitoring of the distribution sub-sector for improved accountability and system reliability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20industry" title=" power industry"> power industry</a>, <a href="https://publications.waset.org/abstracts/search?q=industrialization" title=" industrialization"> industrialization</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/179971/investigating-the-performance-of-power-industry-in-a-developing-nation-for-industrialization-and-environmental-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179971.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">72</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">10012</span> Optimization of Line Loss Minimization Using Distributed Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Sambath">S.

Moreover, the choice of DG is even more attractive since it provides not only benefits in power loss minimisation, but also a wide range of other advantages including environment, economic, power qualities and technical issues. This paper is an intent to quantify and analyse the impact of distributed generation (DG) in Tamil Nadu, India to examine what the benefits of decentralized generation would be for meeting rural loads. We used load flow analysis to simulate and quantify the loss reduction and power quality enhancement by having decentralized generation available line conditions for actual rural feeders in Tamil Nadu, India. Reactive and voltage profile was considered. This helps utilities to better plan their system in rural areas to meet dispersed loads, while optimizing the renewable and decentralised generation sources. <p
