摘要电动汽车数量的增长及其用电需求的增加将会对电网产生明显的影响,针对电动汽车用户行为的随机性和特殊性,分析了分散式电动汽车充放电模型;充分考虑电价和充放电电池折算成本对用户行为的影响,采用削峰填谷调度策略,引导用户在低谷时期充电、高峰时期放电;引入博弈的概念分析用户间行为模式,建立分散式充放电博弈模型,通过求解其纳什均衡来求解最优调度策略;最后以某区域内数据进行算例仿真,验证了模型的合理性和有效性。

Abstract：The growth of electric vehicles and increase of electricity demand will have a significant impact on the grid. The distributed charging and discharging model of electric vehicle is analyzed considering the randomness and particularity of PHEV users’ behavior. Considering the effects of price and discounted cost of the battery on charging and discharging behavior of the users, a load shifting scheduling strategy is used to guide the electric vehicle users to charge during the low load periods and discharge in peak load periods. In order to analyze user’s behavior, the concept of the game is used to create a distributed charging and discharging game model whose Nash equilibrium is solved to obtain the optimal scheduling policy. Finally, a simulation based on the data of a specific region shows that the model is reasonable and effective.

Key words： Plug-in hybrid electric vehicle(PHEV) control strategy load shifting Nash equilibrium
