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

In this project, to provide incessant charging during islanded, grid-connected and DG-connected modes, a solar PV (Photovoltaic) array, a Battery Energy Storage (BES), a Diesel Generator (DG) set and a grid-based EV Charging Station (CS) are used .The charging station is mainly designed to charge the Electric Vehicle (EV) battery using a solar Photo Voltaic (PV) array and a BES. However, the charging station intelligently takes power from the grid or DG (Diesel Generator) set in the event of an empty storage battery and inaccessible solar PV array generation. However, in order to achieve optimum fuel efficiency under all loading conditions, the power from the DG collection is drawn in a way that often operates at 80-85% loading. In addition, the charging station controls generator voltage and frequency without a mechanical speed controller in conjunction with the storage battery. In addition, to obtain ceaseless charging, the PCC (Point of Common Coupling) voltage is synchronized to the grid/generator voltage. In order to improve the operating efficiency of the charging station, the charging station also conducts the vehicle to grid active/ reactive power transfer, vehicle to home and vehicle to vehicle power transfer. Using the Matlab/Simulink software, the operation of the charging station is validated.
