Optimal siting and sizing of battery in varying PV generation by utilizing genetic algorithm in distribution system

This study presents the optimal allocation of battery energy storage system (BESS) with varying photovoltaic (PV) energy production in radial distribution system. The objectives of proposed work are minimization of annual energy losses with proper installation of PV with BESS. BESS integration with PV project required more attention in terms of sizing, siting and functionality of battery charging / discharging. The simulation results on IEEE 69 bus test system with time-dependent load models show the potential benefit of proposed methodology. Based on the optimization results, the proposed methodology for BESS placement decreases the annual energy losses, enhances the PV penetration and reduces the overvoltage.
