Impact of EV fast charging station on distribution system embedded with wind generation

Abstract

This study presents the synergy between the electric vehicle (EV) fast charging station (FCS) and wind generation. A queuing analysis based 24-h FCS charging demand is presented in the study. The uncertainty in wind speed variation is represented with a Weibull distribution function. The impact on the distribution system is analysed for EV penetration up to 50% and wind generation penetration up to 30%. The excess wind energy, reverse power flow, reduction in network losses and voltage deviation are investigated for the IEEE 123 bus radial distribution system to quantify the interaction between FCS and wind generation. The results show that 30% of wind generation is sufficient to supply 50% EV penetration and reduction in active and reactive energy loss is observed by 10.08% and 10.94%, respectively.
