摘　　要：电动汽车不同的充放电控制与利用策略对电网负荷曲线产生不同的影响,从而影响到峰谷分时电价政策的制定与实施。提出计及电动汽车入网的电价联动模型。首先,应用蒙特卡洛模拟法模拟一定数量电动汽车充放电功率曲线;然后,供电侧基于用户需求响应调整销售侧峰谷分时电价,以优化用户负荷曲线;最后,将用户响应后的用户负荷曲线与电动汽车充放电功率曲线叠加得到新的电网负荷曲线,在此基础上,调整发电侧峰谷上网电价,以平衡用户侧削峰填谷及电动汽车入网给发、供电侧带来的效益。结合实际数据,设置3种电动汽车入网方式和2种充放电电价模式对模型进行仿真,结果验证了模型的有效性。Different control and usage strategies of EV （Electric Vehicle） charging/discharging result in different influences on grid load curve,which then affects the enactment and implementation of TOU（Time- Of-Use power price） policy. A electricity price linkage model considering of V2G（Vehicle to Grid） is proposed. The Monte Carlo simulation method is applied to simulate the charging/discharging curve of a certain amount of EVs. The user load curve is then optimized by adjusting the retail-side TOU according to users＇ response. The updated grid load curve is the superposition of user load curve and EV charging/ discharging curve,based on which,the generation-side TOU is adjusted to balance the benefits brought in by V2G between retail side and generation side. Based on for three V2G modes and two charging/discharging price the practical data,the proposed model is simulated modes,verifying its effectiveness.
