摘　　要：电动汽车(EV)利用其储能特性向电网提供辅助服务,既能缓解EV数量急剧增加带来的负荷压力,还可以参与维持电网的稳定运行。但由于EV参与辅助服务过程中存在时空分布随机、可用容量不固定、电池退化加速以及需兼顾用户需求等问题,其控制策略比传统储能更加复杂。基于以上问题,首先,从EV响应机制介绍EV响应电网调度的方式及对应的辅助服务种类。然后,从终端层控制策略和电网层控制策略两个方面对EV参与电网辅助服务的控制策略及其关键技术进行总结。最后,分析了现有研究面临的挑战,并展望了EV参与电网辅助服务控制策略的未来发展方向。Electric vehicles(EVs)can provide auxiliary services to the power grid based on its energy storage characteristics,which can alleviate the load pressure caused by the rapidly increasing number of EVs,and maintain the stable operation of the power grid.However,due to the problems of random spatiotemporal distribution,irregular available capacity,and accelerated battery degradation as well as the need to take user demand into account in the process of EVs participating in auxiliary services,the control strategies of EVs are more complex than that of traditional energy storage.Aiming at the above problems,this paper first introduces the mode of EV responding to power grid dispatching from the response mechanism of EVs and the corresponding types of auxiliary services.Then,the control strategies and key technologies of EVs participating in the auxiliary services of the power grid are summarized from the control strategies of the terminal layer and the grid layer.Finally,the challenges faced by existing research are analyzed and the future development direction of control strategies for EVs participating in the auxiliary services of the power grid is prospected.
