Optimal Sizing and Location of PV/BESS for Microgrid System in Remote Area using Multi-Objective based Genetic Algorithm

This paper presents a multi-objective based genetic algorithm to design the suitable of a solar power generation unit connected with an energy storage unit for a remote area. Due to voltage stability problems in remote areas, the optimal design of renewable energy sources is significant for computing their sizing and location. The renewable energy sources must be designed under optimal power system stability using a multi-objective based genetic algorithm technique. The two objective functions of the proposed study are minimizing the total power loss and maximizing the voltage stability index. The backward and forward sweep methods are chosen to calculate the power flow for the radial distribution system. The IEEE 33 bus test system is also preferred to ensure the proposed method. The simulation results showed that the optimal PV/BESS sizing and location were installed 939 kW at bus no. 12, the voltage amplitude was 0.964 p.u., and the total power loss was 114.121 kW, respectively. The total power loss can be reduced by 44%.
