Abstract

With the rapid development of PV charging station with storage system, due to the inadequate utilization of solar energy in traditional off-gird charging stations and grid-connected charging stations, this paper present a novel connecting and off-grid PV charging station with storage system, which with stable structure, and good scalability, and ability to take full advantage of solar energy. Then we analyzed the grid-connected inverter's control strategy in detail, and because of the inverter's limited capacity with nonlinear load when the station was off-grid, this paper proposed an improved control method by adding output current feedback loop. In order to make full use of PV energy, an energy management strategy had been proposed in this work based on the light intensity to divide the charging station operation into four kinds of modes. Simulation tests, conducted in Matlab/Simulink, about the switching between the four conditions demonstrate the validity of energy management strategies.
