Real Time Simulation of Microgrid Based EV Charging Stations Under Fault Condition

Electric vehicles (EVs) are regarded as portable power sources that may be connected to any infrastructure, including the power grid, in various geographic locations to create a dynamically altering system. Vehicle-to-grid (V2G) andGrid-to-vehicle (G2V) connections are regarded as crucial components of smart grid that can significantly improve the system's performance in a variety of ways. The power system's performance is significantly improved by the control method for integrating EVs. The purpose of this study is to use RSCAD/RTDS to examine the real-time performance of various control techniques for integrating electric vehicles with RES-based microgrids (µg) under symmetrical fault (LLLG) conditions. Constant V control and constant Q controlare the control techniques used for G2V and V2G connections, which maintain continuity of charging in abnormal conditions, stability of µg, and limit peak overshoot current under abnormal conditions. This type of µg-based charging station (CS) is more appropriate for large parking lots, workplace charging, and university campuses.
