Impact of Wind Distributed Generation on Distribution Systems Embedded with Electric Vehicles

Abstract

The deployment of electric vehicles (EVs) requires some changes in the power grid to support the additional demand needed to charge the EVs. Renewable-based sources can deliver this excess charging power. This paper investigates the harmony between wind base generation (WDG) and EVs for different WDGs and EVs penetration levels. The paper evaluates the active and reactive power, the number of transformers overloaded, and the number of houses experiencing under voltage in the distribution system's presence of WDGs and EVs. IEEE-37 node distribution system is modeled, including secondary system drops in open DSS, to evaluate the impact of WDGs and EVs integration in the distribution system. The simulation results show that 30% WDG integration is sufficient to supply the active power needed to charge EVs at 50% penetration level; however, this may result in reactive power flow back to the substation.
