The four distributions are Weibull distribution, lognormal distribution, Gamma distribution, and inverse Gaussian distribution. The wind speed data utilized in this study is hourly average wind speed data collected from a wind farm in Texas city in the United States for five years. Two methods are used to get parameters of the abovementioned distributions, where the first one is a numerical method called the maximum likelihood method and the second one is a novel artificial intelligence method developed in 2021 called Aquila Optimizer. Histogram bars and the probability density function for the four probability distribution functions are presented to visualize the fitting of each graph. All probability distribution functions are compared using actual wind readings obtained from site and data obtained from distribution curve by correlation coefficient (R2), root means square error (RMSE), and Chi-square (X2). The Gamma distribution function gives the best fitting curve, which proves that not always Weibull is the best choice to represent wind speed distribution but selecting of PDF depends on wind speed data under study.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131099737","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}

The Egyptian government is currently working to extent the area of cultivated land, especially in remote and rural areas. Since these areas are not connected to the national electric grid, it was necessary to migrate to the new and renewable energy alternatives. Due to Egypt's geographical location, solar energy is one of the most viable choices to these new technologies. Solar inverter is considered as one of the most important components of solar energy systems especially those operating irrigation pumps. This study details the design and development of a single stage solar photovoltaic (PV) inverter that powers a water pump for irrigation. The pump is driven by a three phase AC induction motor powered by the inverter output. A new control approach could be used to control the suggested three phase boost type inverter. The suggested inverter can inject sinusoidal currents into induction motors that drive pumps. The proposed topological design, as well as the analysis and operation concept, are addressed. To demonstrate the suggested inverter's effectiveness, simulation results are run in Matlab/Simulink software. Finally, Computer simulations and experimental verification have shown encouraging results and it is felt that the proposed topology has good potential for applications in water pumping systems.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127201140","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}

A reduction in power loss, as well as improvement of voltage profiles would be the consequence of optimizing both the location and size of capacitor banks (CBs) and distributed generation (DGs). This can be obtained as a result of the improvement in both voltage stability index (VSI) and voltage magnitude deviations (VD). However, this process must be carried out carefully since the improper size and/or location of DGs may negatively impact the distribution networks. This research presents an optimization-based algorithm for optimal sizing and placement of DGs and CBs. For this purpose, the Jellyfish search algorithm (JS) is employed to solve the optimization model. To elucidate the efficiency of the proposed algorithm, different cases have been considered, starting with the CBs allocation only, the DGs allocation only, and then the allocation of both the CBs and DGs. While their active and reactive power capabilities are taken into consideration. Furthermore, a multi-objective optimization that considers the technical, economic, and emission objectives are also carried out. The results show that the JS delivers preferable results in terms of improving technical, economic, and emission objectives. Furthermore, the results indicate a superior operation when having a controllable power factor (pf) DGs. The calculations have been done for the IEEE-33 bus system using MATLAB software.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123664338","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}

Converting the existing alternating current lines to direct current for higher transmission ratings is one of the optimum solutions. One way of averting new power lines construction caused by a deficiency of appropriate right-of-way is to change overhead power lines from AC to DC. Four hybrid line configurations are suggested. The first configuration is double-circuit working with AC voltage of 500 kV with a bipolar circuit of DC voltage of ±500 kV without modifications with the transmission system, while the second, third, and fourth configurations are double-circuit working with 500 kV AC with a bipolar circuit of a voltage of ±500 kV with required conductor and/or tower modification. Therefore, the power frequency electric field calculations under the high voltage overhead transmission line have caused wide public concern. In this paper, the charge simulation method is utilized to explain the two-dimensional (2-D) electric fields underneath the high voltage overhead transmission lines.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129629830","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}
