Abstract

According to power capacity shortage and harmonic pollution caused by the development of electric vehicles (EV), a photovoltaic (PV) charging system with the function of active power filter (APF) is designed. The system could provide charging power and harmonic compensation for electric vehicle charging machines at the same time. When sunlight is insufficient the PV charging system could continue to work in APF mode. In this paper, detailed analyses of system structure and control algorithms are given. Finally, the proposed system is simulated in PSCAD/EMTDC, and the simulation results validate the correctness and feasibility.
