| Summary: | The growing adoption of Electric Vehicles will lead to an increase in the number of charging stations, which can introduce several problems to power distribution networks. Research on incorporating Distributed Generators (DGs) and Electric Vehicle Charging Stations (EVCS) into radial distribution systems (RDS) is expanding to enhance voltage profiles, reduce losses, meet growing power demands, and raise the voltage stability index (VSI). This paper uses a multi-objective optimization approach metaheuristic algorithm, specifically the Whale Optimization Algorithm (WOA), Zebra Optimization Algorithm (ZOA), and Puma Optimization Algorithm (POA), to determine the optimal size and placement of DG units in the presence of EVCS. The objectives include reducing the average voltage deviation index (AVDI) and raising VSI. The proposed methodology is tested on IEEE 33-bus and 69-bus systems under six scenarios: a base case without EVCS or DG (Case 1), non-optimized EVCS (Case 2), optimized EVCS alone (Case 3), and EVCS combined with three DG operation modes in Cases 4, 5, and 6. Case 6 shows the most favorable results, where POA reduces losses by 85.46% and 96.27% and raises voltage levels to 0.9888 p.u. and 0.9942 p.u. for the IEEE 33- and 69-bus systems, respectively. Although WOA and ZOA slightly outperform POA in certain indicators like AVDI and VSI, Overall POA consistently achieves the most balanced and robust improvements, confirming its capability to enhance distribution system efficiency and voltage stability. |
