摘要：

The functions of rapid charging station for EVs(Electric Vehicles) are gradually developing towards the direction of composite charging station integrating comprehensive energy such as wind, photovoltaic, storage, and so on. Choosing a charging optimization strategy that can improve the benefits of all parties in the fast charging system is helpful to promote EVs and new energy industry. In this context, a charging optimization strategy is developed to improve the comprehensive benefits of EVs and composite charging stations by means of electricity price incentive. Firstly, the comprehensive optimal path planning model of EVs is established based on the charging time cost and charging economic cost of EVs. Then, according to the different fast charging load and vehicle flow obtained from EV decision results, the benefit optimization model of composite charging station is constructed by dispatching the energy storage in the station, with the optimal comprehensive cost of EVs and the optimal comprehensive benefit of composite charging stations as the dual optimization objectives. Taking an 18 km × 18 km road network in a certain region as the example, the proposed optimization strategy is simulated, and the simulative results show that the proposed optimization strategy can effectively reduce the comprehensive charging cost of EVs and greatly improve the comprehensive benefit of composite charging stations. © 2022, Electric Power Automation Equipment Press.
