Impact of fast charging stations on the voltage flicker in the electric power distribution systems

Abstract

Fast Charging Station (FCS) will be deployed on the highways. These fast charging stations are characterized by the high power, which is needed to reduce the charging time of the plug-in electric vehicle. Therefore, the impact of such high power fast charging stations on the electric power quality in the electric power distribution system needs to be quantified. The power demand of the fast charging stations may be seen by the distribution grid as an additional load that is superimposed on the existing load demand. In this paper, the Monte Carlo (MC) method is proposed to probabilistically estimate the power demand of the plug-in electric vehicles when they charge from the fast charging station and the proper means of assessing the voltage flicker in the electric power distribution system will be quantified.
