Methodology for Impact Analysis of Electric Vehicles Charging Stations in Low Voltage Distribution Networks

Abstract

Electric vehicle sales increase at a rapid rhythm annually, however, potential negative impacts of charging stations on the power distribution grid can be a barrier to the widespread adoption of this technology. In this sense, this paper presents an analytical methodology for allocating electric vehicle charging stations in low voltage networks to reduce the impact on the voltage profile of the system. In addition, the proposed method allows estimating the maximum three-phase power that can be installed in each bus, which can be useful for sizing charging stations and for planning studies of the distribution system.
