摘要

Vehicle-grid interaction has emerged as an effective method for power system peaking, promoting renewable energy consumption and stabilizing grid fluctuations. Charging stations play a critical role in this interaction, providing charging services to electric vehicles (EVs) and facilitating vehicle-to-grid (V2G) services. This paper proposes an intelligent scheduling strategy to help charging stations balance these two services. A mathematical model is developed to determine the optimal charging and discharging ratios for EVs at each moment to maximize operational profit. Through numerical simulations, the study demonstrates that vehicle-grid interaction can effectively reduce the idle times of charging stations, leading to increased revenue generation for the stations.
