The energy storage characteristics of electric vehicle(EV)battery swapping stations present new opportunities for enhancing the resilience of urban distribution networks. However,vehicle-to-grid(V2G)swapping stations exhibit weak consistency among internal battery clusters,and their power capacity is significantly affected by users' battery swapping behavior,making them unsuitable for direct use in distribution-side energy storage scheduling. To address this issue,a secondary frequency regulation control strategy for V2G swapping stations that accounts for the consistency of battery clusters is proposed. First,a user frequency regulation willingness model for EVs participating in V2G services is constructed by quantitatively analyzing key factors such as economic incentives,time costs,and battery degradation. Then,a frequency regulation loss function for the battery clusters of the swapping station is formulated.The active balancing of the battery energy levels is achieved by incorporating penalty terms into the objective function. Finally,a distributed control strategy for V2G swapping stations based on the consensus algorithm is established,aiming to minimize the total frequency regulation loss.Through the iteration of consensus variables,the proposed strategy meets the requirements for secondary frequency regulation of the power grid.Simulation results demonstrate that the proposed strategy satisfies the secondary frequency regulation needs of the power grid.The strategy also optimizes the frequency regulation capabilities of the battery clusters,achieving balanced energy levels and safe operation status of the swapping station.
