Impact of electric vehicle charging stations on reliability of distribution network

Abstract

The progress in battery technology and the growing concerns regarding environmental pollution has initiated transportation electrification. With the replacement of Internal Combustion Engine (ICE) driven vehicles with Electric Vehicles (EV) an adverse impact of EV charging load on operating parameters of the power system has been noticed. Large charging load of fast charging stations degrade the operating parameters of the power system. Reliability is one of the pivotal operating parameters of the distribution network whose degradation will result in customer dissatisfaction. This work aims to investigate and quantify the impact of EV charging station load on reliability of IEEE 33 bus test system which is a standard radial network.
