The proposed system injects PV power into the grid, by feeding the SAPF; to eliminate harmonics currents and compensate reactive power produced by nonlinear loads. To inject the photovoltaic power to the grid we use a boost converter controlled by a Fuzzy logic (FLC) algorithm for maximum power point tracking (MPPT). The SAPF system is based on a two-level voltage source inverter (VSI); P-Q theory algorithm is used for references harmonic currents extraction. The overall system is designed and developed using MATLAB/Simulink software. Simulation results confirm the performance of the grid-connected photovoltaic system based on SAPF. For the MPPT controller, the results show that the proposed FLC algorithm is fast in finding the MPPT than conventional techniques used for MPPT like perturbed and observed (P&O). The simulated compensation system shows its effectiveness such as the sinusoidal form of the currents and the reactive power compensation. The proposed solution has achieved a low Total Harmonic Distortion (THD), demonstrating the efficiency of the presented method. Also, the results determine the performances of the proposed system and offer future perspectives of renewable energy for power quality improvement.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115869208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the protection of semiconductor devices and their operation at a safe level are required. Semiconductor power devices, resistors, and capacitors usually have parasitic inductances and capacitances. When a rapid switching transition occurs in the switching devices, it creates a noise, an electromagnetic interference and ringing, on the waveforms. These issues in power switching devices can be resolved by either replacing the switching device with another switch that has rated to exceed the stress or by using a series Resistor-Capacitor (RC) circuit to reduce the stresses to a safe level. The former solution increases the cost, while the snubber circuit, which is a simple RC circuit, is popular and is commonly used for any practical switching circuit, such as power converters, motor drivers, and power electronic devices. Although some works have been addressed in designing the RC snubber circuit, those studies are either based on simple work, or they involve very complex method with results that are often difficult to interpret. In this paper, therefore, we establish how to design an RC snubber circuit experimentally for a buck converter. The buck converter is modelled in PSpice software with and without the RC snubber circuit, where the comparison can be made. The model results show that the current across the switching device is reduced by the RC snubber circuit. In addition, the experimental results validate and verify the effectiveness of the RC circuit and eliminate the ringing and the noises.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131138970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this manner, this may result in partial reduction in power demand hence import of primary sources may gradually decline as well as foreign dependence on energy. Furthermore this lets decrease power losses in transmission lines by reducing power generation capacity in power stations. The widely use of wind turbines and photovoltaic systems in residential and official buildings depends on being economic investment and operation costs. The unit investment cost shows no big difference in all the renewable systems but, to make operation cost lower the balance between production and consumption at any time interval must be maintained without shedding loads. For instance, in case of an hour time interval this balance should be maintained for 24 times in a day however this may not always be possible since sources of renewable energy are irregular. At some time intervals, a power boost is needed either by adding a power source to renewable system or by shedding loads according to their priorities but this is not desired case. In this study, the problem with 7 constraints was solved by a combinatorial optimization based the real-coded genetic algorithms to reduce operation cost to acceptable level and balance between generation and consumption at all the time intervals. The results are encouraging and meaningful for similar applications.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127651439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
