Analyzing the Effects of Electric Mobility Charging Harmonics on Power Grid

Abstract

EVs are restricted in quantity compared to fuel-based cars, but that will change soon. EVs provide environmental and social advantages. The electricity demand to charge these cars will skyrocket, straining the power system. Thus, several EV charging stations will be connected to the grid. Harmonics will be created, affecting voltage stability and power quality. In this Paper, harmonic analysis and THD are assessed with an increase in charging stations. This study considers transformer loads, harmonics, and voltage instability. Using an LCL filter at the rectifier end reduces harmonics for a same number of charging cars.
