Deployment Impact of Electric Vehicle Charging Stations on Radial Distribution System

Abstract

Future transportation is expected to rely on electric vehicles due to their durability and the reduced emissions of greenhouse gases and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$CO_{2}$</tex> . However, the continual increase in the penetration of an electrical load leads to several other problems, including voltage configuration, identifying the best placement location for electric vehicle charging stations, and increasing net operating power losses of the distribution system. And also reduced voltage stability amplitude after deploying electric vehicle charging stations to the distribution network. As mentioned, it is essential to deploy the two algorithm-based appropriate electric vehicle charging stations in the proper location. One is the mathematical modeling-based electric vehicle charging station load, and the other is the random modeling-based electric vehicle charging station load. This study is based on the type of electric vehicle charging stations and their location and observed the voltage profile configuration, total power of the system, total line losses, real power, and reactive power. The proposed approach is verified on the IEEE-33 bus system with and without electric vehicle charging station modes and simulated using MATLAB programming tools. Finally, to signify the importance of electric vehicle charging station load systems, the authors will discuss the strengths and weaknesses of each solution. And also discuss the comparison between mathematical modeling-based electric vehicle charging station load and random modeling-based electric vehicle charging station load.
