At present, there is a two-ways energy flow in electric distribution grids due to the growth of distributed energy resources. So, there are many sources of error in $mutext{PMU}$ system data. In this paper, Pearson correlation is used with the help of a Binary Neural Network (BNN) classifier to detect the errors in $mutext{PMU}$ voltage measurements. Two BNNs are used in this paper. The first BNN is used to detect the injected error in the measured voltage magnitude. Meanwhile, the second BNN is used to detect the injected error in the measured voltage phase angle. The row sum of the correlation matrix is used as an input to BNN that indicates the weight of relation between a group of voltage measurements. The proposed method is tested for Assiut-university radial sub-feeder and the results showed a robust and an accurate performance for errors detection in $mutext{PMU}$ voltage measurements.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"30 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":"130308564","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 all of these systems, cost and ease of installation and maintenance are major factors. This paper discusses the design of an axial flux switching generator with field winding excitation for a direct-drive wind energy conversion system. The design saves cost, reduces maintenance, and increases efficiency due to the absence of a gearbox. In addition, axial generators are designed with a large number of poles and have a higher power-to-weight ratio, and are suitable for small rotational speeds. The proposed generator will be a double external rotor with a fixed stator sandwiched between them 24/20 stator /rotor pole three-phase generation winding with a rotational speed range from (300 to 1000 rpm). This design will be studied through analytical equation and also by Finite Element model on ANSYS Maxwell Software. This design provides the best compatibility between performance characteristics and ease of manufacture and installation. The output power, voltage, load, and no-load characteristics are provided in this paper. The proposed design has given good performance results that fits wind applications especially for rural electrification.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"63 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":"114037117","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}

Consequently, the temperatures of the cable elements and the soil in contact with the cable surface change up and down. In some field applications the cables must be installed in non-metallic protective ducts. One of the merits of the cable installation inside duct is to save the cable from mechanical damage and to prevent human accidents. The goal of this article is to investigate the performance of the cables that are installed inside non-metallic ducts in case of dynamic loading conditions. Based on the heat balance of the cable thermal circuit nodes, IEC 60853–2 and IEC 60287standards proposed model in dynamic loading for cables that are installed in non-metallic protective tubes is constructed and used in the calculation of the cables' components and their surrounding soils temperatures. Extremely increase is noticed in the temperature of cable components in case of installing the cable inside protective duct. Considerable reduction in the temperature of the cable elements is observed when the cable is directly buried in the soil comparing with its installation in protective duct.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"47 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":"114826619","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}

Wind speed (WS) is one of the most challenging weather variables to predict. Therefore, there are many approaches to predict WS including traditional approaches and up to artificial intelligence (AI) based approaches. The target is to obtain the highest possible accuracy in prediction at minimal error. In this paper, WS will be predicted using a modest symbolic model which aims to predict WS at a specific location based on WS of the nearest weather station to that place. This model depends on the displacement vector between the weather station and the place at which the WS is to be predicted. In the proposed case study, a symbolic prediction model (SPM) was evaluated on different places at Cairo governorate based on different scenarios. Error has been calculated which proved that the accuracy of prediction using the proposed SPM is analogous to other sophisticated techniques in the literature. This model is not limited to predict WS but can be extended to any stochastic variable that rely on the displacement vector between two points, such as temperature and air pressure.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"135 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":"133630855","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 proposed inverter topology develops the basic split-source inverter with a voltage-lift cell constructed from three capacitors, two inductors, and four diodes to increase the boosting capability. A relatively high voltage dc-dc boosting factor is achieved with a reduced input dc-current ripple with this combination. Consequently, this inverter topology can achieve a high voltage gain at the ac output terminals. The proposed inverter topology and its mode of operations are described in detail in this paper. In addition, the mathematical relations based on the steady-state analysis that illustrate the working principle and the main characteristics of this inverter have been introduced. Moreover, a modified space vector modulation (SVPWM) scheme is used in this paper to control the inverter switches and to reduce the input current ripples. It can be found that the proposed topology with the given SVPWM schemes increases the dc-boosting capability. The main drawback of this topology is the utilization of more passive elements in the dc-side. Three-phase SSI simulation models have been constructed and simulated using MATLAB/SIMULINK®. Finally, the simulation results are presented to validate the feasibility of this study.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"26 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":"134175709","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 main contribution of this paper is to effectively estimate the rotor position of the machine with a direct estimation without any need for PI controller in the position observer procedure. Moreover, the estimated speed signal is obtained with a simplified method without any need for additional observers to detect the speed from the estimated position signal. To assure the observability of the proposed sensorless speed-control system, a complete analysis supported with the test results under the normal operation are realized.

Also, the AVOA's progress has been verified through a comparison with the symbiotic organisms search algorithm. Overall, discussions are presented on the enhanced performance of the LFC of the two-area power grid under study with the proposed PDμN – IλT controller.

As a result, the primary goal of this research is to devise a viable strategy for accommodating wave energy conversion systems (WEC) while lower the rate of fossil fuel consumption. In this research, a study to investigate the practicability of the WEC system at the Mediterranean Sea of the Egyptian water is conducted. In terms of the wave amplitude and period, the monthly available energy is estimated. An optimal PI via particle swarm optimization controller linear permanent magnet synchronous generator (LPMSG) is investigated. The proposed on-grid system relies on the Archimedes wave swing tool, which is mechanically coupled to the LPMSG. The WEC system is connected to the grid via a transformer, transmission line, and an inverter. Meanwhile, the LPMSG output power is rectified and fed to a supercapacitor. In order to cover the transient stability, the d-axis current and dc-link voltage regulators are established in terms of the PI scaling factors to smoothen the extracted intermittent WEC power. The developed WEC system is validated through annualized real historical data and is checked via MATLAB/Simulink environment.","PeriodicalId":141478,"journal":{"name":"2021 22nd International Middle East Power Systems Conference (MEPCON)","volume":"40 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":"128803004","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}
