Harmonic Impact on the Power Distribution Network due to 30 KW EV Chargers – A Case Study

The worldwide e-mobility boom is an important development in the direction of sustainable resource use and environmental protection. The need for infrastructure for charging electric vehicles is growing as countries prepare for their widespread adoption. But when connected to the utility distribution network, EV chargers-which act as non-linear loads- create harmonics, frequency deviation, voltage imbalance and volatility, which may adversely affect power quality. Since 25 KW and 30 KW EV chargers are wall-mountable and small, which simplifies and lowers installation expenses, these are the best options for charging in a variety of locations, such as offices, homes, businesses and public spaces, it is critical to understand how they affect the utility distribution system. Therefore, the implications of installing 30 KW DC chargers at public and commercial charging stations connected to the power utility network are examined in this paper.
