Abstract Considering the problems of (vehicle-to-grid) V2G scheduling and electric vehicle users’ convenience,an optimization model of cluster charging and discharging of electric vehicles based on the priority is presented to achieve the interactive strategies of vehicle-to-aggregator (V2A).This paper analyzes the influence of declaring information on aggregator’s strategies and establishes the evaluation index system for electric vehicles,which takes reporting capacity,time,battery depletion and integrity as the indices.Then the scheduling priority of electric vehicles based on the entropy method is determined.Aggregator can determine the local optimized scheduling scheme according to the schedule plan made by the scheduling organization.The simulation results show that the impact of multiple indices of electric vehicles on scheduling strategy are considered and the scheduling plan provided by the scheduling organization for the aggregator can be obtained through the proposed method.

Key words： Vehicle-to-aggregator scheduling priority optimal charge and discharge plan control strategy
