Abstract :
In order to solve the contradiction between the rapid pulse charging demand of EV and the grid power change rate limits, it is necessary to add an energy storage buffer system to the smart charging station, which can alleviate the adverse influence on the grid during the fast charging process of EVs. Firstly, the topology structure of EV smart charging station with an energy storage buffer system and the charging power characteristics of different types of batteries are studied, then the operation mode of energy storage buffer system is analyzed based on the above investigation. Furthermore, a control strategy of energy storage buffer system for smart charging station is proposed. Using Matlab/Simulink software, a model of smart charging station which contains an energy storage buffer system is built, and the dynamic characteristics simulation and analysis of smart charging station with different rate of power change instructions are conducted to verify the correctness and effectiveness of the control strategy. The simulation results show that the proposed energy storage buffer system and its control strategy can meet the high power density demand during EV charging and can also effectively reduce the adverse effects of the aggregation of charging load on the distribution network.
