Electric Vehicles (EVs) play a crucial role in advancing environmental and economic sustainability, yet their widespread adoption poses risks to the electrical grid, including voltage instability and increased peak load stress. Research has highlighted the potential of V2G-enabled EV chargers to mitigate these issues by providing reactive power support to the grid. Despite these advancements, the impact of reactive power injection on different types of networks, such as resistive versus inductive distribution networks, remains inadequately studied. This paper addresses this gap by investigating how reactive power affects various low-voltage (LV) distribution networks, providing insights into optimizing EV integration and enhancing grid stability. The analysis employs a modified IEEE 13-bus network to evaluate the effects of V2G support by EVs across different network types. The results demonstrate a strong correlation between the type of distribution network and key performance metrics, including the grid's voltage profile, charging rates, and EV charging times. These findings emphasize the importance of considering distribution networks when assessing the potential benefits of V2G technology for grid stability and EV charging efficiency.

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.
