The predictive control algorithm utilises the discrete nature of the full-bridges and predicts the future state of the system. The objective of the MPC is to reduce the cost function by selecting the switching states from a finite set of switching for the converters in the next sample period. Consequently, the corresponding switching state is used as the firing command to the converter. The MPC is applied to control the power flow between the two bridges with an isolation transformer in the middle. The proposed MPC for bi-directional DC-DC converter is simulated with MATLAB Simulink and shows that the amount of reactive power is reduced by avoiding the phase shift between the primary and secondary sides of the high frequency transformer and allows for power transfer at unity power factor. Finally, a performance comparison between MPC and PI control algorithm is performed.","PeriodicalId":174878,"journal":{"name":"2022 23rd International Middle East Power Systems Conference (MEPCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131169687","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}

Recently, many studies have assured that the pulse energization-based electrostatic precipitator (ESP) is a good candidate for enhancing the removal efficiency of high-resistivity fractional particles, resulted from commercial and industrial applications. Consequently, this paper proposes a multi-module pulse power supply, in series-stacked version, fed from isolated high- frequency square-wave AC sources via utilizing multiple of ring transformers. Each module comprises of the voltage-doubler (VD)/marx-generator (MG) stages. In the presented approach, the two various output pulse types, namely, rectangular pulse and multilevel one, are proposed. The suggested approach is featured with its modular construction and its scalability for generating any desired voltages' values for pulse energization with a controllable repetition rate and an adjustable pulse width. The operational principles, along with design equations, have been illustrated for the presented scheme. A numerical comparison is carried out to show the merits of the suggested pulse generator compared to the other approaches in the literature. The findings of simulated case-study are used to validate the presented pulse generator.","PeriodicalId":174878,"journal":{"name":"2022 23rd International Middle East Power Systems Conference (MEPCON)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134644891","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}

Operation of an isolated hybrid micro-grid (HMG) system requires frequency regulating as well as the voltage. The frequency and power generation control in a power system is usually referred to as a load frequency control. In this paper, the biomass power plant is the main balancing mechanism of the proposed hybrid micro-grid. Speed governor of biomass power plant is implemented using both conventional proportional-integral- derivative (PID) and Proportional-Integral-Derivative-Acceleration (PIDA) based controllers to track system uncertainties and enhancing the performance of HMG. Atom search optimization (ASO) is applied to fine tune the proposed PID and PIDA controllers by minimizing the integral of time multiplied absolute error (ITAE). The proposed HMG and its controllers are applied and tested in the MATLAB/Simulink based simulation environment. In this paper, PID and the PIDA controller have been compared between them to notice the fluctuation behavior of frequency under various system uncertainties scenarios, it is concluded that the PIDA controller scheme provides more reliable system frequency than conventional PID controller.","PeriodicalId":174878,"journal":{"name":"2022 23rd International Middle East Power Systems Conference (MEPCON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115732105","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}

This system's essential problem is controlling the frequency in island mode. Using the synchronous generator (SG) control approach, the microgrid frequency is more stable due to the inertial features of the SG. In this regard, this paper presents a control algorithm for voltage source converters (VSC)-based distributed generators (DGs), which emulates the principal behavior of synchronous machines and can support inertia to the grid and reduce frequency gradients considering the parallel operation of the SG. The controller is designed based on droop control theory, and a supervisory center controller is implemented to maintain system frequency close to a nominal value of the whole microgrid. The simulation results demonstrate that the system frequency is stabilized even in different and sudden load changes in the island mode where the microgrid is fed by multiple VSC units and a SG. The Simulink model of the system is designed using MATLAB Simulink Software.","PeriodicalId":174878,"journal":{"name":"2022 23rd International Middle East Power Systems Conference (MEPCON)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114417330","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}

Electrical ciruits are developed to model PV cells/modules. Parameter extraction of the appropriate PV modules is one of the hot research topics that attract researchers' for possible assessing the performance and operation and control issues of PVs. Parameters estimation of PV cells is a highly nonlinear optimization problem, in this regard several optimization algorithms are exploited to tackle this challenge. In this study, the improved real coded genetic algorithm (IRGA) spreads an enhanced performance of the well-known genetic algorithms. The IRGA investigated parameter extraction of the most accurate diode PV module model for PV commercial modules. The attained result of the IRGA shows the high accuracy of the estimated parameters. This can be validated from the examination of the identified parameters to plot the I-v curve and show the accompaniment of the estimated and measured values. Moreover, the IRGA convergence curve shows up a competitive convergence rate and robustness when assessed with other recent optimization algorithms.","PeriodicalId":174878,"journal":{"name":"2022 23rd International Middle East Power Systems Conference (MEPCON)","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132492151","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}
