With the promotion of the transition of energy structure, the utilization of renewable energy is gradually increasing, and it is difficult to meet the demand by relying on traditional units to regulate frequency deviation. Therefore, in order to solve this problem, the use of distributed resources (DRs) to participate in frequency regulation auxiliary services is considered. The DRs are mainly considered as air conditioners, electric vehicle charging piles and energy storage. First, the characteristics and satisfaction evaluation methods of DRs are considered. Then, DRs are controlled coordinately based on the state-potential game theory and centralized to externally present as a whole to participate in the frequency regulation auxiliary services. Finally, the feasibility and effectiveness of aggregation and coordinated control of DRs to participate in frequency regulation auxiliary services under the proposed control strategy are demonstrated through simulation cases, and the participation of energy storage, charging piles, and controllable loads in the fast frequency regulation under multiple time scales is verified.
