Electric vehicle, as a kind of moving load, its behavior of charging and discharging will have a huge impact on the power grid. This article does some researches on coordination charging and discharging strategy of electric vehicles between different regions. Considering the load characteristics of the area and parking rules of electric vehicles, the paper proposes an optimal control strategy from different perspectives of the power grid side, intermediary side and user side. The power grid side considers load fluctuations; the intermediary side considers the benefits of charging and discharging, the user side considers charge-discharge cycles and user convenience. Together it establishes the corresponding multi-objective function and uses multi-objective genetic algorithm to calculate the result. Finally a demonstration is given to prove the validity of this method. Simulation result shows that the multi-objective optimization method can achieve the overall demand of the power grid side, intermediary side and user side.
