Research on Power Quality Control Method of V2G System of Electric Vehicle Based on APF

This paper studies the influence of electric vehicle V2G system on the power grid after it is connected to the power grid, analyzes the basic principle of harmonic pollution caused by the charging and discharging machine of V2G electric vehicle on the power grid, and puts forward a parallel active power filter with direct power control method for active control, so as to achieve the effect of eliminating harmonics and smoothing power. Simulation results show that this method can guarantee both charging effect and power quality.
