China's electric vehicle ownership is rapidly increasing yearly

and urban distribution network operations face new challenges and development opportunities. To give full play to the better controllability and flexible energy storage characteristics of electric vehicles and to improve the optimization efficiency of electric vehicle-assisted distribution grid operation

the electric vehicle-to-grid(V2G)operation taken as the research object and a multi-objective optimization dispatch strategy under the V2G mode has been proposed.Firstly

based on the electrical operation characteristics of EVs

energy storage devices

rooftop PVs

and equipment state constraints

the V2G optimization operation model contains multiple operation subjects.Second

the multi-objective V2G optimization decision-making method is proposed based on the operation mode

and the hierarchical analysis method is used to quantify the objective focus of the multi-objective optimization scheduling to achieve the flexible balance between the different demand response objectives of“economic focus”and“response focus.”Finally

CPLEX is used to simulate the case

and the comparison results show that the multi-objective optimal scheduling strategy proposed in this paper can realize the multi-objective optimal scheduling of EVs and optimize the performance of the operation area under different target-oriented scheduling modes.
