OPTIMAL POWER MOBILIZATION FOR ELECTRIC VEHICLE CHARGING STATIONS IN DISTRIBUTION NETWORKS WITH DISTRIBUTED GENERATIONS AND BATTERY STORAGE SYSTEMS

Tóm tắt

The transition to clean energy in the transportation sector has driven a rapid increase in Electric Vehicles, necessitating effective solutions for Electric Vehicle Charging Stations. This study proposes an improved optimization algorithm, combining a chaotic search function and the Runge Kutta optimizer, to address the optimal power dispatch problem for EVCS integrated with Vehicle-to-Grid  technology in Distribution Networks featuring Distributed Generation and Battery Energy Storage Systems. Simulations on IEEE 33 and 69 bus systems under various scenarios reveal that Vehicle-to-Grid optimizes EVCS power allocation without requiring Battery Energy Storage Systems, ensuring economic and technical efficiency. Simulation results given show that, in the IEEE 33 bus network, peak charging power reaches 0.88 MW at 18:00, while maximum discharging power is 0.643 MW at 8:00, 11:00, and 14:00. Similarly, in the IEEE 69 bus network, discharging peaks at 0.877 MW at 10:00, with charging maxing out at 0.88 MW during late night hours. These findings highlight Vehicle-to-Grid flexibility in adapting to EVCS demands, optimizing costs and system operation.
