Batteries from electric vehicles (EVs) have the potential to be used in microgrids as energy storage devices. By storing energy when there is excess (Grid-to-Vehicle, or G2V) and returning it to the grid (Vehicle-to-Grid, or V2G) when needed, they may aid in micro-grid energy management. The development of appropriate control systems and infrastructure is necessary to make this idea a reality. This study presents an architecture for establishing a V2G-G2V system in a micro-grid employing level-3 rapid charging of EVs. An EV interface is provided via a dc rapid charging station in a modeled micro-grid test system. V2G-G2V power transmission is shown via simulation research. According to test findings, EV batteries are actively regulating power in the microgrid via G2V-V2G modes of operation. The controller provides excellent dynamic performance in terms of dc bus voltage stability, and the charging station design assures low harmonic distortion of grid injected current.
