Voltage Sensitivity Analysis and Demand Dispatch Option of Electric Vehicle in Smart Grid

The increasing integration of Electric Vehicle (EV) poses unique challenges for voltage and frequency regulation in electric distribution grids. EVs are at present the most reliable substitutes for standard fossil fuel-based cars. The mobility and variability due to EV loads exacerbates the problem of voltage regulation in distribution grids that are characterized by X/R ratios. This paper examines the effect of different operations and impact of EV on the system having voltage sensitivity analysis and choosing an appropriate time of charging and discharging cycles. Coding was done on the distributed system simulator for obtaining the results. To inspect its effectiveness and the performance of EV, IEEE-34 Nodes Test Feeder network is used. The adopted platform to perform the designed task is designed on Open Distribution System Simulator (OpenDSS).
