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.
