Description
Summary:Aiming at the stochasticity of electric vehicle user charging, an electric vehicle time distribution model is established. Based on the IEEE33 distribution system, the Monte Carlo method is used to simulate the scaled electric vehicle disordered charging access to the distribution network and to study the change of the total system network loss and the mean value of the voltage specification when charging random loads access to different nodes. Next, the three-phase unbalanced metrics are observed at the EV access nodes. The results show that the charging load access to different distribution network nodes has an obvious impact on power quality. Finally, further EV grid optimization measures are given.
