Electric Vehicle Load Characteristic Analysis and Impact of Regional Power Grid

With the popularity of electric vehicles, a large number of charging stations connected to the grid, will bring large impact for the power, voltage and current of grid. This paper based on several scenarios of charging modes, such as plug and charge, night charging and intelligent charging, the corresponding EV load models have been established. Finally, an analysis is performed for the load characteristics of Regional power grid to demonstrate the impacts of different EV charging scenarios.
