Optimal Planning Strategy for Electric Vehicle Charging Station integrated with Battery Backed Solar Photovoltaic System in Distribution Network

This study presents a planning methodology for embedding electric vehicle charging stations (EVCS) integrated with battery backed solar photovoltaic distributed generators (BBSPVDG) in the 33 bus radial distribution system (RDS) using a combinational multi-objective function based on priori method. To solve the problem, the genetic algorithm (GA) and whale optimization algorithm (WOA) were used. The findings indicate that when an energy management strategy is correctly implemented, significant technological and economical gains can be realised. Additionally, the study demonstrates that combining solar photovoltaic (SPV) and battery energy storage systems (BESS) with EVCS decreases line losses and improves the voltage profile of the system.
