The UPQC is a combination of shunt and series active power filter (APF). It is one of the best solutions towards the mitigation of voltage sags and swells problems on distribution network. This analysis can provide the helpful information to well understanding the interaction between the series filter, the shunt filter, the DC bus link and electrical network. The mathematical analysis is based on active and reactive power flow through the shunt and series active power filter. Wherein series APF can absorb or deliver the active power to mitigate a swell or sage voltage where in the both cases it absorbs a small reactive power quantity whereas the shunt active power absorbs or releases the active power for stabilizing the storage capacitor’s voltage as well as the power factor correction. The voltage sag and voltage swell are usually interpreted through the DC bus voltage curves. These two phenomena are introduced in this paper with a new interpretation based on the active and reactive power flow analysis inside the UPQC. For simplifying this study, a linear load is supposed in this digital simulation. The simulation results are carried out to confirm the analysis done. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UPQC" title="UPQC">UPQC</a>, <a href="https://publications.waset.org/abstracts/search?q=Power%20flow%20analysis" title=" Power flow analysis"> Power flow analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=shunt%20filter" title=" shunt filter"> shunt filter</a>, <a href="https://publications.waset.org/abstracts/search?q=series%20filter." title=" series filter."> series filter.</a> </p> <a href="https://publications.waset.org/abstracts/21038/using-power-flow-analysis-for-understanding-upqcs-behaviors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21038.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">577</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">10270</span> Renewable Energy Interfaced Shunt Active Filter Using a Virtual Flux Direct Power Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Bengourina">M.

If the reactive power is compensated at the consumer end, the need for reactive power flow from generators to the load can be avoided and hence the overall power loss can be reduced. In this scenario, this paper presents a succinct method called JSS method for allocation of reactive power losses to consumers connected to radial distribution networks in a deregulated environment. The proposed method has the advantage that no assumptions are made while deriving the reactive power loss allocation method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deregulation" title="deregulation">deregulation</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20power%20loss%20allocation" title=" reactive power loss allocation"> reactive power loss allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20distribution%20systems" title=" radial distribution systems"> radial distribution systems</a>, <a href="https://publications.waset.org/abstracts/search?q=succinct%20method" title=" succinct method"> succinct method</a> </p> <a href="https://publications.waset.org/abstracts/47667/a-succinct-method-for-allocation-of-reactive-power-loss-in-deregulated-scenario" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47667.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">382</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">10267</span> Active Islanding Detection Method Using Intelligent Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kuang-Hsiung%20Tan">Kuang-Hsiung Tan</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Chan%20Hu"> Chih-Chan Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Wu%20Lan"> Chien-Wu Lan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shih-Sung%20Lin"> Shih-Sung Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Te-Jen%20Chang"> Te-Jen Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An active islanding detection method using disturbance signal injection with intelligent controller is proposed in this study. First, a DC\AC power inverter is emulated in the distributed generator (DG) system to implement the tracking control of active power, reactive power outputs and the islanding detection. The proposed active islanding detection method is based on injecting a disturbance signal into the power inverter system through the <em>d</em>-axis current which leads to a frequency deviation at the terminal of the <em>RLC</em> load when the utility power is disconnected. Moreover, in order to improve the transient and steady-state responses of the active power and reactive power outputs of the power inverter, and to further improve the performance of the islanding detection method, two probabilistic fuzzy neural networks (PFNN) are adopted to replace the traditional proportional-integral (PI) controllers for the tracking control and the islanding detection. Furthermore, the network structure and the online learning algorithm of the PFNN are introduced in detail. Finally, the feasibility and effectiveness of the tracking control and the proposed active islanding detection method are verified with experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distributed%20generators" title="distributed generators">distributed generators</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20fuzzy%20neural%20network" title=" probabilistic fuzzy neural network"> probabilistic fuzzy neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=islanding%20detection" title=" islanding detection"> islanding detection</a>, <a href="https://publications.waset.org/abstracts/search?q=non-detection%20zone" title=" non-detection zone"> non-detection zone</a> </p> <a href="https://publications.waset.org/abstracts/39253/active-islanding-detection-method-using-intelligent-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39253.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">393</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">10266</span> Nine-Level Shunt Active Power Filter Associated with a Photovoltaic Array Coupled to the Electrical Distribution Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahzouh%20Zoubir">Zahzouh Zoubir</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouzaouit%20Azzeddine"> Bouzaouit Azzeddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Gahgah%20Mounir"> Gahgah Mounir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of more and more electronic power switches with a nonlinear behavior generates non-sinusoidal currents in distribution networks, which causes damage to domestic and industrial equipment. The multi-level shunt power active filter is subsequently shown to be an adequate solution to the problem raised. Nevertheless, the difficulty of adjusting the active filter DC supply voltage requires another technology to ensure it. In this article, a photovoltaic generator is associated with the DC bus power terminals of the active filter. The proposed system consists of a field of solar panels, three multi-level voltage inverters connected to the power grid and a non-linear load consisting of a six-diode rectifier bridge supplying a resistive-inductive load. Current control techniques of active and reactive power are used to compensate for both harmonic currents and reactive power as well as to inject active solar power into the distribution network. An algorithm of the search method of the maximum power point of type Perturb and observe is applied. Simulation results of the system proposed under the MATLAB/Simulink environment shows that the performance of control commands that reassure the solar power injection in the network, harmonic current compensation and power factor correction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Actif%20power%20filter" title="Actif power filter">Actif power filter</a>, <a href="https://publications.waset.org/abstracts/search?q=MPPT" title=" MPPT"> MPPT</a>, <a href="https://publications.waset.org/abstracts/search?q=pertub%26observe%20algorithm" title=" pertub&observe algorithm"> pertub&observe algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20array" title=" PV array"> PV array</a>, <a href="https://publications.waset.org/abstracts/search?q=PWM-control" title=" PWM-control"> PWM-control</a> </p> <a href="https://publications.waset.org/abstracts/74962/nine-level-shunt-active-power-filter-associated-with-a-photovoltaic-array-coupled-to-the-electrical-distribution-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74962.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">344</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">10265</span> Planing the Participation of Units Bound to Demand Response Programs with Regard to Ancillary Services in the PQ Power Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farnoosh%20Davarian">Farnoosh Davarian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present research focuses on organizing the cooperation of units constrained by demand response (DR) programs, considering ancillary services in the P-Q power market. Moreover, it provides a comprehensive exploration of the effects of demand reduction and redistribution across several predefined scenarios (in three pre-designed demand response programs, for example, ranging from 5% to 20%) on system voltage and losses in a smart distribution system (in the studied network, distributed energy resources (DERs) such as synchronous distributed generators and wind turbines offer their active and reactive power for the proposed market).GAMS, a specialized software for high-powered modeling, is used for optimizing linear, nonlinear, and integer programming challenges. GAMS modeling is separate from its solution method, which is a notable feature. Thus, by providing changes in the solver, it is possible to solve the model using various methods (linear, nonlinear, integer, etc.). Finally, the combined active and reactive market challenge in smart distribution systems, considering renewable distributed sources and demand response programs in GAMS, will be evaluated. The active and reactive power trading by the distribution company is carried out in the wholesale market. What is demanded is active power. By using the buy-back/payment program, it is possible for responsive loads or aggregators to participate in the market. The objective function of the proposed market is to minimize the price of active and reactive power for DERs and distribution companies and the penalty cost for CO2 emissions and the cost of the buy-back/payment program. In this research, the objective function is to minimize the cost of active and reactive power from distributed generation sources and distribution companies, the cost of carbon dioxide emissions, and the cost of the buy-back/payment program. The effectiveness of the proposed method has been evaluated in a case study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20behavior" title="consumer behavior">consumer behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=demand%20response" title=" demand response"> demand response</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution%20cost" title=" pollution cost"> pollution cost</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20active%20and%20reactive%20market" title=" combined active and reactive market"> combined active and reactive market</a> </p> <a href="https://publications.waset.org/abstracts/196152/planing-the-participation-of-units-bound-to-demand-response-programs-with-regard-to-ancillary-services-in-the-pq-power-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/196152.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">25</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">10264</span> Design of Active Power Filters for Harmonics on Power System and Reducing Harmonic Currents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D%C3%BCzg%C3%BCn%20Akmaz">Düzgün Akmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%BCseyin%20Eri%C5%9Fti"> Hüseyin Erişti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last few years, harmonics have been occurred with the increasing use of nonlinear loads, and these harmonics have been an ever increasing problem for the line systems. This situation importantly affects the quality of power and gives large losses to the network. An efficient way to solve these problems is providing harmonic compensation through parallel active power filters. Many methods can be used in the control systems of the parallel active power filters which provide the compensation. These methods efficiently affect the performance of the active power filters. For this reason, the chosen control method is significant. In this study, Fourier analysis (FA) control method and synchronous reference frame (SRF) control method are discussed. These control methods are designed for both eliminate harmonics and perform reactive power compensation in MATLAB/Simulink pack program and are tested. The results have been compared for each two methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parallel%20active%20power%20filters" title="parallel active power filters">parallel active power filters</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonic%20compensation" title=" harmonic compensation"> harmonic compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20quality" title=" power quality"> power quality</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonics" title=" harmonics"> harmonics</a> </p> <a href="https://publications.waset.org/abstracts/11639/design-of-active-power-filters-for-harmonics-on-power-system-and-reducing-harmonic-currents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11639.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">464</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">10263</span> Optimal Injected Current Control for Shunt Active Power Filter Using Artificial Intelligence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Berbaoui">Brahim Berbaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a new particle swarm optimization (PSO) based method is proposed for the implantation of optimal harmonic power flow in power systems.

Ferro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ensuring power quality and stability in fusion power plant grids is crucial for the successful integration of demonstration power plant (DEMO) into future electrical networks. This paper presents the preliminary design of an active power filter (APF) aimed at compensating reactive power in the DEMO toroidal field power supply. In the high-current coil configuration, assuming ITER-like thyristor converter technology, the DEMO toroidal field power supply (TFPS) is a 2-quadrant AC/DC 12-pulse converter with a no-load voltage of ±1 kV and operating current of 105 kA. This AC/DC converter is fed by two converter transformers with the following characteristics: voltage ratio V₁/V₂₀ = 22 kV/0.74 kV and capacity rating S = 2 x 58 MVA. The proposed APF employs a control strategy based on the park transform, which enables efficient detection and mitigation of harmonic distortions and reactive power fluctuations. The methodology involves systematic modeling of the APF, allowing, thus, the extraction of the fundamental and harmonic components from the power signals. A robust control scheme is then implemented to ensure dynamic compensation of reactive power and to minimize total harmonic distortion (THD). Preliminary design is carried out through comprehensive simulation studies to assess the effectiveness of the APF under conditions mimicking real-time grid scenarios. In particular, the APF has been shown to maintain a power factor (cos φ) that nearly always complies with the stringent guidelines typically required for nuclear installations to ensure both efficient and safe operation. Results demonstrate that the APF can effectively enhance power quality by significantly reducing distortion and increasing the power factor, thereby improving the overall reliability of the DEMO electrical power system. The findings suggest that the integration of this APF design in the ITER-like solution can play a pivotal role in maintaining grid compliance with international power quality standards, thus contributing to the secure operation of future nuclear fusion power plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20power%20filter" title="active power filter">active power filter</a>, <a href="https://publications.waset.org/abstracts/search?q=DEMO%20power%20plant" title=" DEMO power plant"> DEMO power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=park%20transform" title=" park transform"> park transform</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20factor" title=" power factor"> power factor</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20quality" title=" power quality"> power quality</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20power%20compensation" title=" reactive power compensation"> reactive power compensation</a> </p> <a href="https://publications.waset.org/abstracts/199106/preliminary-design-of-an-active-power-filter-for-harmonic-distortion-and-reactive-power-compensation-in-demo-toroidal-field-power-supply" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/199106.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">1</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">10261</span> Self-Tuning-Filter and Fuzzy Logic Control for Shunt Active Power Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaddari%20Faiza">Kaddari Faiza</a>, <a href="https://publications.waset.org/abstracts/search?q=Mazari%20Benyounes"> Mazari Benyounes</a>, <a href="https://publications.waset.org/abstracts/search?q=Mihoub%20Youcef"> Mihoub Youcef</a>, <a href="https://publications.waset.org/abstracts/search?q=Safa%20Ahmed"> Safa Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Active filtering of electric power has now become a mature technology for reactive power and harmonic compensation caused by the proliferation of power electronics devices used for industrial, commercial and residential purposes.

Ensuring tuning of state estimator is a repeated process and cannot be left once a good solution is obtained. This paper attempts to demonstrate methods to improve state estimator solution by identifying incorrect modelling and telemetry inputs to the application. In this work, identification of database topology modelling error by plotting static network using node-to-node connection details is demonstrated with examples. Analytical methods to identify wrong transmission parameters, incorrect limits and mistakes in pseudo load and generator modelling are explained with various cases observed. Further, methods used for active and reactive power tuning using bus summation display, reactive power absorption summary, and transformer tap correction are also described. In a large power system, verifying all network static data and modelling parameter on regular basis is difficult .The proposed tuning methods can be easily used by operators to quickly identify errors to obtain the best possible state estimation performance. This, in turn, can lead to improved decision-support capabilities, ultimately enhancing the safety and reliability of the power grid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20power%20tuning" title="active power tuning">active power tuning</a>, <a href="https://publications.waset.org/abstracts/search?q=database%20modelling" title=" database modelling"> database modelling</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=state%20estimator" title=" state estimator"> state estimator</a> </p> <a href="https://publications.waset.org/abstracts/194306/state-estimator-performance-enhancement-methods-for-identifying-errors-in-modelling-and-telemetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194306.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">21</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">10259</span> Simulink Library for Reference Current Generation in Active DC Traction Substations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mihaela%20Popescu">Mihaela Popescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandru%20Bitoleanu"> Alexandru Bitoleanu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is focused on the reference current calculation in the compensation mode of the active DC traction substations.

The multi-line and multi-type Flexible alternating current transmission system (FACTS) controllers are playing a vital role to regulate power flow through the transmission line. Unified power flow controller and interline power flow controller can be utilized to control reactive power flow through the transmission line. In a restructured power system, the demand of such controller is being popular due to their inherent capability. The transmission pricing by using reactive power cost allocation through modified matrix methodology has been proposed. The FACTS technologies have quite costly assembly, so it is very useful to apportion the expenses throughout the restructured electricity industry. Therefore, in this work, after embedding the FACTS devices into load flow, the impact on the costs allocated to users in fraction to the transmission framework utilization has been analyzed. From the obtained results, it is clear that the total cost recovery is enhanced towards the Reactive Power flow through the different transmission line for 5 bus test system. The fair pricing policy towards reactive power can be achieved by the proposed method incorporating FACTS controller towards cost recovery of the transmission network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interline%20power%20flow%20controller" title="interline power flow controller">interline power flow controller</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20pricing" title=" transmission pricing"> transmission pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=unified%20power%20flow%20controller" title=" unified power flow controller"> unified power flow controller</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20allocation" title=" cost allocation"> cost allocation</a> </p> <a href="https://publications.waset.org/abstracts/109581/influence-of-power-flow-controller-on-energy-transaction-charges-in-restructured-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109581.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">10256</span> Advanced Fuzzy Control for a Doubly Fed Induction Generator in Wind Energy Conversion Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santhosh%20Kumat%20T.">Santhosh Kumat T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Priya%20E."> Priya E.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The control of a doubly fed induction generator by fuzzy is described.

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">262</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">10253</span> Performance Comparison of Droop Control Methods for Parallel Inverters in Microgrid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ismail">Ahmed Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Baysal"> Mustafa Baysal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although the energy source in the world is mainly based on fossil fuels today, there is a need for alternative energy generation systems, which are more economic and environmentally friendly, due to continuously increasing demand of electric energy and lacking power resources and networks. Distributed Energy Resources (DERs) such as fuel cells, wind and solar power have recently become widespread as alternative generation. In order to solve several problems that might be encountered when integrating DERs to power system, the microgrid concept has been proposed. A microgrid can operate both grid connected and island mode to benefit both utility and customers. For most distributed energy resources (DER) which are connected in parallel in LV-grid like micro-turbines, wind plants, fuel cells and PV cells electrical power is generated as a direct current (DC) and converted to an alternative currents (AC) by inverters. So the inverters are assumed to be primary components in a microgrid. There are many control techniques of parallel inverters to manage active and reactive sharing of the loads. Some of them are based on droop method. In literature, the studies are usually focused on improving the transient performance of inverters. In this study, the performance of two different controllers based on droop control method is compared for the inverters operated in parallel without any communication feedback. For this aim, a microgrid in which inverters are controlled by conventional droop controller and modified droop controller is designed. Modified controller is obtained by adding PID into conventional droop control. Active and reactive power sharing performance, voltage and frequency responses of those control methods are measured in several operational cases. Study cases have been simulated by MATLAB-SIMULINK. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20and%20reactive%20power%20sharing" title="active and reactive power sharing">active and reactive power sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20generation" title=" distributed generation"> distributed generation</a>, <a href="https://publications.waset.org/abstracts/search?q=droop%20control" title=" droop control"> droop control</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrid" title=" microgrid"> microgrid</a> </p> <a href="https://publications.waset.org/abstracts/29844/performance-comparison-of-droop-control-methods-for-parallel-inverters-in-microgrid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29844.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">597</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">10252</span> An Efficient Tool for Mitigating Voltage Unbalance with Reactive Power Control of Distributed Grid-Connected Photovoltaic Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malinwo%20Estone%20Ayikpa">Malinwo Estone Ayikpa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rapid increase of grid-connected PV systems over the last decades, genuine challenges have arisen for engineers and professionals of energy field in the planning and operation of existing distribution networks with the integration of new generation sources. However, the conventional distribution network, in its design was not expected to receive other generation outside the main power supply. The tools generally used to analyze the networks become inefficient and cannot take into account all the constraints related to the operation of grid-connected PV systems. Some of these constraints are voltage control difficulty, reverse power flow, and especially voltage unbalance which could be due to the poor distribution of single-phase PV systems in the network. In order to analyze the impact of the connection of small and large number of PV systems to the distribution networks, this paper presents an efficient optimization tool that minimizes voltage unbalance in three-phase distribution networks with active and reactive power injections from the allocation of single-phase and three-phase PV plants. Reactive power can be generated or absorbed using the available capacity and the adjustable power factor of the inverter. Good reduction of voltage unbalance can be achieved by reactive power control of the PV systems. The presented tool is based on the three-phase current injection method and the PV systems are modeled via an equivalent circuit. The primal-dual interior point method is used to obtain the optimal operating points for the systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Photovoltaic%20system" title="Photovoltaic system">Photovoltaic system</a>, <a href="https://publications.waset.org/abstracts/search?q=Primal-dual%20interior%20point%20method" title=" Primal-dual interior point method"> Primal-dual interior point method</a>, <a href="https://publications.waset.org/abstracts/search?q=Three-phase%20optimal%20power%20flow" title=" Three-phase optimal power flow"> Three-phase optimal power flow</a>, <a href="https://publications.waset.org/abstracts/search?q=Voltage%20unbalance" title=" Voltage unbalance"> Voltage unbalance</a> </p> <a href="https://publications.waset.org/abstracts/65491/an-efficient-tool-for-mitigating-voltage-unbalance-with-reactive-power-control-of-distributed-grid-connected-photovoltaic-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65491.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">337</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">10251</span> Voltage Stability Assessment and Enhancement Using STATCOM -A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Chawla">Puneet Chawla</a>, <a href="https://publications.waset.org/abstracts/search?q=Balwinder%20Singh"> Balwinder Singh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, increased attention has been devoted to the voltage instability phenomenon in power systems.

Long subsea cables produce reactive power, which should be compensated in order to limit transmission losses, to optimize the transmission capacity, and to keep the grid voltage within the safe operational limits. Installation cost of wind farm includes the structure design cost and electrical system cost. India has targeted to achieve 175GW of renewable energy capacity by 2022 including offshore wind power generation. Due to sea depth is more in India, the installation cost will be further high when compared to European countries where offshore wind energy is already generating successfully. So innovations are required to reduce the offshore wind power project cost. This paper presents the optimized techniques to reduce the installation cost of offshore wind firm with respect to electrical transmission systems. This technical paper provides the techniques for increasing the current carrying capacity of subsea cable by decreasing the reactive power generation (capacitance effect) of the subsea cable. There are many methods for reactive power compensation in wind power plants so far in execution. The main reason for the need of reactive power compensation is capacitance effect of subsea cable. So if we diminish the cable capacitance of cable then the requirement of the reactive power compensation will be reduced or optimized by avoiding the intermediate substation at midpoint of the transmission network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=offshore%20wind%20power" title="offshore wind power">offshore wind power</a>, <a href="https://publications.waset.org/abstracts/search?q=optimized%20techniques" title=" optimized techniques"> optimized techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system" title=" power system"> power system</a>, <a href="https://publications.waset.org/abstracts/search?q=sub%20sea%20cable" title=" sub sea cable"> sub sea cable</a> </p> <a href="https://publications.waset.org/abstracts/91131/optimized-techniques-for-reducing-the-reactive-power-generation-in-offshore-wind-farms-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91131.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">204</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">10249</span> Grid-Connected Doubly-Fed Induction Generator under Integral Backstepping Control Combined with High Gain Observer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oluwaseun%20Simon%20Adekanle">Oluwaseun Simon Adekanle</a>, <a href="https://publications.waset.org/abstracts/search?q=M%27hammed%20Guisser"> M'hammed Guisser</a>, <a href="https://publications.waset.org/abstracts/search?q=Elhassane%20Abdelmounim"> Elhassane Abdelmounim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Aboulfatah"> Mohamed Aboulfatah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, modeling and control of a grid connected 660KW Doubly-Fed Induction Generator wind turbine is presented. Stator flux orientation is used to realize active-reactive power decoupling to enable independent control of active and reactive power. The recursive Integral Backstepping technique is used to control generator speed to its optimum value and to obtain unity power factor. The controller is combined with High Gain Observer to estimate the mechanical torque of the machine. The most important advantage of this combination of High Gain Observer and the Integral Backstepping controller is the annulation of static error that may occur due to incertitude between the actual value of a parameter and its estimated value by the controller.

On the other hand, the on-board chargers can also supply energy storage system applications such as reactive power compensation, voltage regulation, and power factor correction without the need of engaging the battery with the grid and thereby preserving its lifetime. It presents the design motives of single-phase on-board chargers in detail and makes a classiﬁcation of the chargers based on their future vehicle-to-grid usage. The pros and cons of each different ac–dc topology are discussed to shed light on their suit- ability for reactive power support. This paper also presents and analyzes the differences between charging-only operation and capacitive reactive power operation that results in increased demand from the dc-link capacitor (more charge/discharge cycles and in- creased second harmonic ripple current). Moreover, battery state of charge is spared from losses during reactive power operation, but converter output power must be limited below its rated power rating to have the same stress on the dc-link capacitor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20storage%20system" title="energy storage system">energy storage system</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20unit" title=" battery unit"> battery unit</a>, <a href="https://publications.waset.org/abstracts/search?q=cost" title=" cost"> cost</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20sizing" title=" optimal sizing"> optimal sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=plug-in%20electric%20vehicles%20%28PEVs%29" title=" plug-in electric vehicles (PEVs)"> plug-in electric vehicles (PEVs)</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/44195/reactive-power-control-with-plug-in-electric-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44195.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">346</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">10247</span> Fractionation of Biosynthetic Mixture of Gentamicins by Reactive Extraction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Kloetzer">L.

Among them, three exhibit the most important biological activity: gentamicins C1, C1a, C2, and C2a. The separation of gentamicin from the fermentation broths at industrial scale is rather difficult and it does not allow the fractionation of the complex mixture of gentamicins in order to increase the therapeutic activity of the product. The aim of our experiments is to analyze the possibility to selectively separate the less active gentamicin, namely gentamicin C1, from the biosynthetic mixture by reactive extraction with di-(2-ethylhexyl) phosphoric acid (D2EHPA) dissolved in dichloromethane, followed selective re-extraction of the most active gentamicins C1a, C2, and C2a. The experiments on the reactive extraction of gentamicins indicated the possibility to separate selectively the gentamicin C1 from the mixture obtained by biosynthesis. The extraction selectivity is positively influenced by increasing the pH-value of an aqueous solution and by using a D2EHPA concentration in organic phase closer to the value needed for an equimolecular ratio between the extractant and this gentamicin. For quantifying the selectivity of separation, the selectivity factor, calculated as the ratio between the degree of reactive extraction of gentamicin C1 and the overall extraction degree of gentamicins were used. The possibility to remove the gentamicin C1 at an extractant concentration of 10 g l-1 and pH = 8 is presented. In these conditions, it was obtained the maximum value of the selectivity factor of 2.14, which corresponds to the modification of the gentamicin C1 concentration from 31.92% in the biosynthetic mixture to 72% in the extract. The re-extraction of gentamicins C1, C1a, C2, and C2a with sulfuric acid from the extract previously obtained by reactive extraction (mixture A – extract obtained by non-selective reactive extraction; mixture B – extract obtained by selective reactive extraction) allows for separating selectively the most active gentamicins C1a, C2, and C2a. For recovering only the active gentamicins C1a, C2, and C2a, the re-extraction must be carried out at very low acid concentrations, far below those corresponding to the stoichiometry of its chemical reactions with these gentamicins. Therefore, the mixture resulted by re-extraction contained 92.6% gentamicins C1a, C2, and C2a. By bringing together the aqueous solutions obtained by reactive extraction and re-extraction, the overall content of the active gentamicins in the final product becomes 89%, their loss reaching 0.3% related to the initial biosynthetic product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=di-%282-ethylhexyl%29%20phosphoric%20acid" title="di-(2-ethylhexyl) phosphoric acid">di-(2-ethylhexyl) phosphoric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=gentamicin" title=" gentamicin"> gentamicin</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20extraction" title=" reactive extraction"> reactive extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=selectivity%20factor" title=" selectivity factor"> selectivity factor</a> </p> <a href="https://publications.waset.org/abstracts/6005/fractionation-of-biosynthetic-mixture-of-gentamicins-by-reactive-extraction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6005.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">328</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">10246</span> Investigation of Wind Farm Interaction with Ethiopian Electric Power’s Grid: A Case Study at Ashegoda Wind Farm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fikremariam%20Beyene">Fikremariam Beyene</a>, <a href="https://publications.waset.org/abstracts/search?q=Getachew%20Bekele"> Getachew Bekele</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ethiopia is currently on the move with various projects to raise the amount of power generated in the country. The progress observed in recent years indicates this fact clearly and indisputably. The rural electrification program, the modernization of the power transmission system, the development of wind farm is some of the main accomplishments worth mentioning. As it is well known, currently, wind power is globally embraced as one of the most important sources of energy mainly for its environmentally friendly characteristics, and also that once it is installed, it is a source available free of charge. However, integration of wind power plant with an existing network has many challenges that need to be given serious attention. In Ethiopia, a number of wind farms are either installed or are under construction. A series of wind farm is planned to be installed in the near future. Ashegoda Wind farm (13.2°, 39.6°), which is the subject of this study, is the first large scale wind farm under construction with the capacity of 120 MW. The first phase of 120 MW (30 MW) has been completed and is expected to be connected to the grid soon. This paper is concerned with the investigation of the wind farm interaction with the national grid under transient operating condition. The main concern is the fault ride through (FRT) capability of the system when the grid voltage drops to exceedingly low values because of short circuit fault and also the active and reactive power behavior of wind turbines after the fault is cleared. On the wind turbine side, a detailed dynamic modelling of variable speed wind turbine of a 1 MW capacity running with a squirrel cage induction generator and full-scale power electronics converters is done and analyzed using simulation software DIgSILENT PowerFactory. On the Ethiopian electric power corporation side, after having collected sufficient data for the analysis, the grid network is modeled. In the model, a fault ride-through (FRT) capability of the plant is studied by applying 3-phase short circuit on the grid terminal near the wind farm. The results show that the Ashegoda wind farm can ride from voltage deep within a short time and the active and reactive power performance of the wind farm is also promising. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=squirrel%20cage%20induction%20generator" title="squirrel cage induction generator">squirrel cage induction generator</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20and%20reactive%20power" title=" active and reactive power"> active and reactive power</a>, <a href="https://publications.waset.org/abstracts/search?q=DIgSILENT%20PowerFactory" title=" DIgSILENT PowerFactory"> DIgSILENT PowerFactory</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20ride-through%20capability" title=" fault ride-through capability"> fault ride-through capability</a>, <a href="https://publications.waset.org/abstracts/search?q=3-phase%20short%20circuit" title=" 3-phase short circuit"> 3-phase short circuit</a> </p> <a href="https://publications.waset.org/abstracts/106479/investigation-of-wind-farm-interaction-with-ethiopian-electric-powers-grid-a-case-study-at-ashegoda-wind-farm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106479.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">182</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">10245</span> Power Quality Improvement Using Interval Type-2 Fuzzy Logic Controller for Five-Level Shunt Active Power Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousfi%20Abdelkader">Yousfi Abdelkader</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaker%20Abdelkader"> Chaker Abdelkader</a>, <a href="https://publications.waset.org/abstracts/search?q=Bot%20Youcef"> Bot Youcef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article proposes a five-level shunt active power filter for power quality improvement using a interval type-2 fuzzy logic controller (IT2 FLC). The reference compensating current is extracted using the P-Q theory. The majority of works previously reported are based on two-level inverters with a conventional Proportional integral (PI) controller, which requires rigorous mathematical modeling of the system. In this paper, a IT2 FLC controlled five-level active power filter is proposed to overcome the problem associated with PI controller. The IT2 FLC algorithm is applied for controlling the DC-side capacitor voltage as well as the harmonic currents of the five-level active power filter. The active power filter with a IT2 FLC is simulated in MATLAB Simulink environment. The simulated response shows that the proposed shunt active power filter controller has produced a sinusoidal supply current with low harmonic distortion and in phase with the source voltage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20quality" title="power quality">power quality</a>, <a href="https://publications.waset.org/abstracts/search?q=shunt%20active%20power%20filter" title=" shunt active power filter"> shunt active power filter</a>, <a href="https://publications.waset.org/abstracts/search?q=interval%20type-2%20fuzzy%20logic%20controller%20%28T2FL%29" title=" interval type-2 fuzzy logic controller (T2FL)"> interval type-2 fuzzy logic controller (T2FL)</a>, <a href="https://publications.waset.org/abstracts/search?q=multilevel%20inverter" title=" multilevel inverter"> multilevel inverter</a> </p> <a href="https://publications.waset.org/abstracts/117014/power-quality-improvement-using-interval-type-2-fuzzy-logic-controller-for-five-level-shunt-active-power-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117014.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">186</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">10244</span> Performance Analysis of Shunt Active Power Filter for Various Reference Current Generation Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vishal%20V.%20Choudhari">Vishal V.

Depending upon the type of load the technique has to be chosen. In this paper, six reference current generation techniques viz. instantaneous reactive power theory(IRP), Synchronous reference frame theory(SRF), Perfect harmonic cancellation(PHC), Unity power factor method(UPF), Self-tuning filter method(STF), Predictive filtering method(PFM) are compared for different operating conditions. The harmonics are introduced because of non-linear loads in the system. These harmonics are eliminated using above techniques. The results and performance of system simulated on MATLAB/Simulink platform. The system is experimentally implemented using DS1104 card of dSPACE system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SAPF" title="SAPF">SAPF</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20quality" title=" power quality"> power quality</a>, <a href="https://publications.waset.org/abstracts/search?q=THD" title=" THD"> THD</a>, <a href="https://publications.waset.org/abstracts/search?q=IRP" title=" IRP"> IRP</a>, <a href="https://publications.waset.org/abstracts/search?q=SRF" title=" SRF"> SRF</a>, <a href="https://publications.waset.org/abstracts/search?q=dSPACE%20module%20DS1104" title=" dSPACE module DS1104"> dSPACE module DS1104</a> </p> <a href="https://publications.waset.org/abstracts/19083/performance-analysis-of-shunt-active-power-filter-for-various-reference-current-generation-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19083.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">596</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">10243</span> Artificial Neural Networks Controller for Active Power Filter Connected to a Photovoltaic Array </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Dehini">Rachid Dehini</a>, <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Berbaoui"> Brahim Berbaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objectives of shunt active power filter (SAPF) is to preserve the power system from unwanted harmonic currents produced by nonlinear loads, as well as to compensate the reactive power. The aim of this paper is to present a (PAPF) supplied by the Photovoltaic cells ,in such a way that the (PAPF) feeds the linear and nonlinear loads by harmonics currents and the excess of the energy is injected into the power system. In order to improve the performances of conventional (PAPF) This paper also proposes artificial neural networks (ANN) for harmonics identification and DC link voltage control. The simulation study results of the new (SAPF) identification technique are found quite satisfactory by assuring good filtering characteristics and high system stability. <p
