Ignorance of any of them will lead the system towards instability and subsequently to grid collapse. In this paper, disturbances caused by the rotor angle stability, such as oscillations in power delivery, deviation in rotor speed are discussed and the effect of power system stabilizer for damping of those oscillations are investigated. To realize the scenario, a synchronous generator connected with an infinity grid is considered as the test system and is modeled in Power System Computer Aided Design software. ST5B static excitation system is deployed to provide the field flux of the synchronous generator and the PSS3B power system stabilizer provides an additional stabilizing signal to the excitation system required for the improvement of the damping performance of the machine. To observe the dynamics of the machine, a fault was introduced at the middle of the transmission line. As the operating point changes in abnormal conditions, conventional PSS is unable to provide satisfactory performance. To overcome this drawback, PSS parameters were tuned by implementing the Down-hill simplex algorithm. It helped in reducing rotor angle oscillations and improving voltage stability as well. The behavior of the machine is presented in the results section to prove the superiority of the soft computing method over the conventional one.","PeriodicalId":208445,"journal":{"name":"2021 IEEE 2nd International Conference on Smart Technologies for Power, Energy and Control (STPEC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115006716","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}

PMBLDCM (permanent-magnet brushless DC motor) has advanced characteristics in comparison to DC & induction motors like high torque to weight ratio, less maintenance, higher efficiency, and simple structure and therefore becoming popular for agriculture-based water pumping and other wide range of applications. This paper presents a solar PV-fed battery-based BLDC motor drive for water pumping applications with InC based MPPT scheme for efficient and optimum power generation. In this article, a two-stage power conversion-based PMBLDCM drive is presented, the first stage is DC to DC Cuk converter to achieve the required MPP voltage level and the second stage is an inverter to get an optimum AC power supply for an effective 1200 mode of conduction. The overall scheme operates in three modes, in the first mode both battery charging and motor pumping operation takes place simultaneously, in the second mode, only battery charging takes place, in the third mode, SPV doesn’t generate any power, and the motor operation is powered by the battery. The proposed scheme is simulated in a MATLAB-Simulink software environment and the obtained results are presented to prove the effectiveness of the proposed drive.","PeriodicalId":208445,"journal":{"name":"2021 IEEE 2nd International Conference on Smart Technologies for Power, Energy and Control (STPEC)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114598422","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}

For the configuration of basic SV controlled DERs connected to grid, variations in grid voltage amplitude within normal range leads to transients in current. Virtual impedance implementation to VSG or SV controlled DERs has the drawbacks of partial current transients suppression, adverse effect of high virtual impedance on system stability and arbitrary design of virtual impedance. Hence, the reactive power loop (RPL) of SV control is improved in this work by incorporating the measured grid voltage rms value. Effective suppression of current transients by the improved SV control is shown through small signal analysis and it is verified by simulations. Further, the SV control with improvement to RPL is tested for grid fault conditions, and it is observed that the current during fault and the current transient after fault recovery might become large. Thus, simple changes to parameters in APL during fault conditions are proposed to keep the current within limits during fault and after fault recovery as well.","PeriodicalId":208445,"journal":{"name":"2021 IEEE 2nd International Conference on Smart Technologies for Power, Energy and Control (STPEC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128764418","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, many challenges can arise while interfacing the renewable energy sources with AC grid. Recent research has proved that the establishment of smart grids with integration of utility grid and renewable sources can provide highly reliable and more competent power system in the cost-effective manner. In India there are many rural areas which have limited supply of electricity. For such location DC microgrid is an attractive and effective technology because of its easy interfacing with renewable sources, utility grid, DC loads and battery storage system. Also, DC grid is proved to be much better over AC grid. This paper describes the implementation of DC microgrid technology for rural electrification that covers solar photovoltaic (PV), AC interfaces, system architecture and energy storage system. The system is purely considered for rural remote locations with or without AC grid. The loads are considered as LED lights, and DC operated Fan. The different switching conditions are considered with load, PV, battery and utility grid. The system is simulated by using MATLAB/Simulink and comprehensive analysis is provided to show the efficiency of the system. Also, the paper provides advantages and challenges of using DC microgrid technology in rural electrification.","PeriodicalId":208445,"journal":{"name":"2021 IEEE 2nd International Conference on Smart Technologies for Power, Energy and Control (STPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130320252","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}
