Analysis of the Impact of Electric Vehicle Charging Station on Power Quality Issues

Abstract

The sector of transport is being electrified because to rising worries about pollution and energy consumption, as well as technological breakthroughs in batteries. As a new technology, electric cars are still trying to find their niche. Its many benefits include less pollutant that contributes to climate change, less fuel use, and simplicity of use. Since chargers function as electric-electronic converters, power quality issues may arise while charging electric vehicles (EVs). More and more people are driving electric vehicles, which brings up concerns about how these vehicles may affect the electricity system and its quality. Power balancing and the effect of charging an electric car on voltage, current, and total harmonic distortion are the primary topics covered in this article. This research presents and analyses power quality concerns in EV charging stations based on monitoring data. Various chargers' harmonic current emissions are studied. The purpose of this study is to examine how the loads placed on the distribution network by electric vehicle charging stations affect reliability indices, power losses, voltage stability, and economic losses. This article uses MATLAB simulations to examine the effects of EVs on the electricity distribution network.
