With the rapid growth of electric vehicle (EV), EV charging load has a significant impact on the safe operation of the power grid. An ordered charging control strategy is proposed in the paper based on differentiated charging price. In the strategy, different charging prices, which are aimed at mobilizing the participation of ordered charging behavior, are accessible for EV users. In nature, relatively lower charging price is for the EV user’s license of the translation of EV charging load, i.e., the EV charging load is permitted to be moved to expected period during which the grid is with valley electricity load. The effectiveness of the proposed method is verified by the analysis of the benefits of various stakeholders.
