Abstract

Electric vehicle (EV) charging stations based on the V2G (Vehicle to Grid) technology support bi-directional energy interaction between grid and electric vehicles. The energy flow from the grid will be injected into the battery when the battery needs to be charged. While the electric vehicle is in a suspended state, the energy will flow from electric vehicles to grid so as to improving the energy utilization. By using the energy storage buffer system, we can compensate the pulse power of EV's fast charging and reduce the adverse influence on the distribution network caused by the fast charging stations. This paper studies the topology structure of fast charging station with energy storage buffer system and the fast charging power characteristics of different types of batteries. Then taking the distribution network real power change limit into account, we propose an operation mode of the energy storage buffer system of the fast charging stations and its current control strategy. Furthermore, to design the storage buffer system module and its control parameters, we combine the configuration of fast charging stations to deduce the operation parameters of the storage buffer system.
