Impact Analysis of Fast Charging to Voltage Profile in PEA Distribution System by Monte Carlo Simulation

This paper presents a method to obtain electric power consumption of plug-in electric vehicle ( PEV) fast charging station by the Monte Carlo simulation. The state of charge ( SoC) of battery, charging time and arrival time to charging station are considered. After obtaining a charging profile, a voltage profile is analyzed by DIgSIENT PowerFactory. Subsequently, an impact analysis of PEV fast charging stations to voltage profile of the Provincial Electricity Authority ( PEA) distribution system is carried out. The simulation results show that charging station affects changes of voltage profile and voltage drop in the distribution system. In addition, the presented method is applicable, even if the rated charging power of charging station is changed, an approach presented in this research can also be applied to analyze the impact.
