Impacts of Low Voltage PEVs Single Phase Charging on Electrical Distribution Network

Abstract

This paper presents impacts of low voltage PEV single phase charging on electrical distribution network. Simulation model and analysis tools under DigSILENT Power Factory program were used in this research. There are 5 case studies under this analysis, where each case operates at different charging time durations between 16.00 and 24.00. Assessment of the impact of PEV charging is performed based on the PEA standards. The simulation results show that all charging case studies increase line loading in the distribution network over the limit by 80%. The voltage at the upstream point of the feeder slightly dropped while at the downstream point dropped 4 times lower. Average line losses for all case studies increase approximately 13.36% compared to the base case study.
