Abstract

In this paper, analysis for the influence of electric vehicle (EV) chargers on grid harmonics is conducted. The simulation model of the power distribution network with vehicle-mounted chargers is established, and the harmonic feature of the charger is analyzed. Considering different State of Charge (SOC) of the chargers and the relationship between harmonic current and initial SOC values of the EVs is established. To reduce the harmonic current caused by EV chargers, an optimization model of coordinated charging has been developed and the optimal solution is obtained by using the PSO algorithm. The validity of the proposed optimal charging schedule is verified through the simulation results.
