In order to balance the spatial distribution of fast charging load and improve electric vehicle(EV)users'charging satisfaction,this paper proposes a dynamic pricing mechanism for fast charging considering the load space balance and the cooperation game of charging stations.First,the travel probability transfer matrix is obtained through inverse geocoding of the actual order data,and the spatial and temporal distribution model of EV charging load is established by combining the road network model and the speed-flow model.Then,the charging station selection decision-making model is established by considering the users'subjective willingness to take into account users'preferences,and the rational decision-making behaviors of the users'charging station selection are simulated.Finally,the dynamic pricing game model in the cooperation mode of fast charging stations in the region is established with the objective of charging station node load balance,and the equilibrium value is solved by an iterative algorithm,while the residual benefits obtained from the cooperative alliance are distributed by using the Shapley value method.The simulation example shows that the proposed dynamic pricing strategy can effectively reduce the load variance of charging station nodes,improve the utilization rate of charging piles and charging station revenues,and reduce the queuing time of users to improve users'satisfaction.
