Abstract |
In this paper, we propose the optimal operation algorithm for electric vehicle (EV) charging system connected with PV and ESS. The conventional method of the EV charging system in which PV and ESS are connected uses ESS only when PV generation is larger than the EV charging amount. In conventional method, the utilization of ESS is low, and the profit of the EV charging service provider is low. Therefore, this paper proposes the optimal operation method for EV charging system that uses ESS to charge during off-peak-load and discharge during peak-load. In the case study, each profits of EV charging service provider applying various EV charging pattern to the conventional method and the proposed method were compared and analyzed. |
