In the DFIG-based wind turbine system, the sinusoidal pulse width modulation (PWM) technique is applied to control the flux, current, and voltage levels. Here, the proportional-integral (PI) blocks indicate PI control methods to regulate the rotor side converter (RSC) and front-end converter (FEC) through the PWM technique to stabilize the DC-link bus voltage. It provides bidirectional power flow in the back-to-back power converter from the electrical machine to the grid and vice-versa. Recently, several research studies have been available in the literature about the electromechanical interaction of the mechanical structure with electrical sections using open-source codes/tools/packages, but it takes high computational time. This paper uses mathematical equations to develop novel codes to interface the wind turbine structure with the DFIG system connected to the grid. The complete mathematical model is simulated under ideal wind condition that takes less computational time using MATLAB/Simulink software.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123219801","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 raw voltage and current signal are fed to the GT-based feature extractor and the standard deviation (SD) of the Gabor feature is further used for training of the EKNN classifier/detector. Three different EKNN classifier modules have been developed to perform the protection tasks. The proposed method's effectiveness has been tested for a a wide range of fault scenarios with varying fault parameters. The validation results show that combining GT with KNN can effectively distinguish between defective and healthy line, thereby achieving excellent performance for fault detection and classification in both AC and HVDC systems.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128533073","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}

Designing a controller for MIBC is a challenging task due to its inherent non-minimum phase behavior. The present paper presents a graphical loop shaping technique for developing the compensator for non-minimum phase (NMP) MIBC. The merit of the suggested method is the reduction of complex calculations for designing a controller. The main objective of the controller design technique is to alleviate the NMP behavior with minimum effort. Time, frequency domain analysis has been performed to comment on the dynamic performance and stability of MIBC. The stability, robustness, and sensitivity of MIBC for different values of gain of the controller are analyzed. The effect of variation of controller gain on system performance has also been studied and discussed. The regulated output voltage has been obtained for variable input voltage with the help of the controller designed. Open-loop and closed-loop simulation results have been presented to validate the proposed controller's usability and efficacy with the converter.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133881385","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}

Proposed method follows the principle of electrical circuit to determine the power flow in the distribution branches and adopts branch oriented approach. It identifies the marginal contribution of real and imaginary part of load current in system losses corresponding to their power consumptions at nodes. Apart from traditional marginal loss coefficient (MLC) methods, however, proposed method recovers entire system losses without an additional step of reconciliation. Average marginal contribution of both real and imaginary part of load current makes proposed method more efficient and adoptable specially for radial structure of DSs. In order to test the proposed method, 28-bus DS is considered. Results of the proposed method are compared and validated with than that of other available methods in literature.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"921 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133108713","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}

Especially in Universities, the campuses have a large number of people in a short period of time, which increases the electric vehicles' charging load. In this paper, an optimized charging and discharging method of EVs within a campus microgrid is proposed, which would significantly improve grid operation stability. This article used the disorderly charging of EVs using probability density functions and the Monte Carlo (MC) method. By analyzing the EVs owners' willingness to charge in the campus area, the distribution of start-of-charge (SOC) of the vehicles, and the EVs' stay time on campus, the amount of charge is estimated. To achieve a suitable charging scenario for a campus microgrid, the analysis parameters are coded and optimized using the Genetic Algorithm (GA). According to the characteristics of university class-times, it is expected that the charging of vehicles entering campus will cause peak-load periods. During the time period from 6:00 to 24:00, 1,000 EVs that follow these plans will exist. The GA algorithm is used to allocate the best charging time for the EVs, thereby adjusting the peak-to-valley gap of the campus power grid. Further, four types of GA are compared and it is realized that the input parameters have a significant impact on the outcomes. The results demonstrate the impact of optimized charging on improving microgrid stability and reducing charging costs.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127842790","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}

However, high penetration of EVs in residential neighborhoods is expected to overburden the local distribution network. Unregulated EV charging has the potential to reduce the lifespan of network equipment, most notably the distribution transformer. The loss of life of a transformer is a function of its internal temperature, which in turn depends on the kVA loading and ambient temperature. Transformer loading is influenced by the level of EV penetration while the ambient temperature varies seasonally. This paper examines the impact of domestic EV charging on the aging of a distribution transformer under multiple penetration levels during summer and winter. The transformer's thermal model is utilized to determine its internal temperature and the rate of aging under different loading levels. The simulation results clearly exhibit the variation in transformer aging with EV deployment under different seasons.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125366149","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}
