摘　　要：随着能源结构转型的推进,可再生能源的使用逐渐增加,仅依靠传统机组调节频率偏差难以满足需求。因此,为了解决此问题,考虑利用分布式资源(DR)参与调频辅助服务,DR主要考虑空调、电动汽车充电桩以及储能。首先,考虑了DR的特性和满意度评价方法;然后,基于状态势博弈理论对DR进行协调控制,将DR集中起来使其对外呈现为一个整体参与调频辅助服务;最后,通过算例仿真证明了该方案下对DR聚合并协调控制参与调频辅助服务的可行性和有效性,并对多时间尺度下储能、电动汽车充电桩以及可控负荷参与快速调频进行了验证。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.
