Effect of electrical vehicle charging on power quality

Abstract

Electric Vehicles(EVs) are a clean energy alternative to gas and energy powered vehicles. They form a crucial part of the present and future automotive. Electric vehicles being non-linear loads could affect the power quality of the grid. In this paper, we present a view of the fluctuations in power factor and Total Harmonic Distortion (THD) levels when varying number of electric vehicles (two wheeler and four wheeler) are connected to the power system. The system was simulated and studied in Simulink. Here, a captive power plant that is supplying power under base load and peak load conditions is considered.
