The Influence of the Electric Vehicle Charging Station on the Power Supply Network with Regard to Power Quality

The European Union (EU) aims to reduce greenhouse gas emissions by 2030 and therefore a proposal has been accepted to improve publicly accessible charging and refueling infrastructure for alternative fuels. This will result in an increasing number of electric vehicles charging stations, which can negatively impact the power grid. Therefore, this paper investigates the impact of electric vehicle charging by a particular charging station on the grid from a power quality perspective. The charging station's harmonic components, reactive power, and power factor during different operating conditions are analyzed. The harmonic analysis for one period of supply voltage and current consumed by the charging station during maximum load, graphs of active power, reactive power, first harmonic power factor, and total power factor for different operating conditions are shown in this paper.
