Implementation of Solar PV- Battery and Diesel Generator Based Electric Vehicle Charging Station

Abstract

Abstract- A solar PV (Photovoltaic) array, a battery energy storage (BES), a diesel generator (DG) set, and grid-based energy storage are all discussed in this study.The EV charging station (CS) is used to offer the constant supply of electricity.Charging modes include islanded, grid connected, and DG set connected.The charging station is primarily intended for solar power.To charge the electric vehicle, a solar PV array and a BES are used.(Electric vehicle) battery However, if the storage battery is depleted and charging station, solar PV array generation not available smartly utilises grid or DG power (Diesel Generator) set. However, the DG set's power is extracted in such a way that to ensure maximum fuel efficiency, always operate at 80-85% loading efficiency in any loading situation. Furthermore, without using a mechanical speed regulator, the charging station manages the generator voltage and frequency in conjunction with the storage battery. Even during nonlinear loads, it assures that the power drawn from the grid or the DG set is at unity power factor (UPF). Furthermore, to provide continuous charging, the PCC (Point of Common Coupling) voltage is synchronised to the grid/generator voltage. For increased charging station operational efficiency, the charging station also performs vehicle to grid active/reactive power transfer, vehicle to house, and vehicle to vehicle power transfer. The charging station's operation is experimentally tested using a prototype created in the lab. EV Charging Station, Solar PV Generation, Power Quality, DG Set are all index terms.
