摘要: 在电力市场环境下,充电站合理优化策略能降低电力成本，甚至通过售电获取收益。文中考虑了电动汽车成为柔性储荷资源的潜力，提出了电力市场和实时电力市场下充电站的调度策略。首先，建立了可调度潜力模型和实时可调度潜力评估模型。同时，考虑充电站与调度中心间的通信延迟，建立了时间延迟计算模型。然后，提出了考虑时间延迟的充电站调度模型策略。最后，基于一个IEEE 33节点配电系统进行了仿真，验证所提策略的有效性。仿真结果表明所提出的可调度潜力计算方法能够增强电动汽车集群参与调度的实时性。

Abstract: Under the power market environment, a reasonable optimization strategy for charging stations can reduce the cost of electricity and even generate revenue through the sale of electricity. In this paper, the potential of electric vehicles to become a flexible load storage resource is considered, and the scheduling strategy of charging stations under power market and real-time power market is proposed. First, a dispatchable potential model and a real-time dispatchable potential assessment model are developed. At the same time, a time delay calculation model is established by considering the communication delay between the charging station and the dispatching center. Then, a charging station scheduling modeling strategy considering time delay is proposed. Finally, simulations based on an IEEE 33-node distribution system are conducted to verify the effectiveness of the proposed strategy. The simulation results show that the proposed schedulable potential calculation method can enhance the real-time performance of EV cluster participation in scheduling.
