Abstract

This study investigates the impact of the electric vehicles (EVs’) battery charging on the distribution system in terms of maximum voltage deviation, voltage unbalance at various locations, transformers overloading, and introducing new peaks into the system. In this research, a 12.47 kV real distribution network has been modeled using real time digital simulator, using real data from a power distributor. The study presents four different scenarios of uncoordinated EVs integration for two different charging times (evening and night) and two different charging rates (level I and level II) at different penetration levels ranging from 10% to 100%. Voltage unbalance at different locations is determined and transformer overloading is analyzed. The influence of EVs charging on the daily load curve is shown. It is noted that actual system data of voltage and current at all intellirupters of the utility distribution system were close to the data of the simulated system.
