Impact of EV Charger on the Utility Grid and Reactive Power Operation of EV

The rapid integration of Electric Vehicles (EV s) poses a significant concern for energy producers, transmitters, and distributors regarding the capability of the existing grid topology and technology. EV owner prefers to use high-rated chargers to reduce the charging time, negatively impacting the grid. This paper focuses on the impact of different power ratings of chargers and the abilities of EV s for reactive power support to the utility grid. This analysis considers two sizes of popular EV chargers to assess their impact on the utility grid. An IEEE 14 bus network is employed in this study to investigate the grid performance with three different levels of EV penetration (small, medium, and high). The simulation results show that the fast chargers can significantly impact the power system, mainly when the EV penetration is very high.
