Because fast charging will shorten battery-cycle lifetime and induce voltage flicker in the system, repeatedly discharging and charging is uneconomic and harmful to the power quality. Therefore, in this paper, only EV discharging model with low discharging rate is considered, which is labeled as Mode 1 or Mode 2 corresponding to the charging
