The main aim of proposed method is, the combination of EV charging, PV generation, and BES enhances the stability and reliability of the power grid.
This paper discusses the detailed modelling of a multiport converter based EV charging station integrated with PV power generation, and battery energy storage system, by using MATLAB/SIMULINK software. In this paper, the control scheme and combination of PV power generation, EV charging station, and battery energy storage (BES) provides improved stabilization including power gap balancing, peak shaving and valley filling, and voltage sag compensation. As a result, the influence on power grid is reduced due to the matching between daily charging demand and adequate daytime PV generation. Simulation results are presented to confirm the benefits at different modes of this proposed multiport EV charging circuits with the PV-BES configuration. Furthermore, SiC devices are employed to the EV charging station to further improve the efficiency. For different modes and functions, power losses and efficiency are investigated and compared in simulation with conventional Si devices based charging circuits.
