A Modeling Method for the Power Demand of Electric Vehicles Based on Monte Carlo Simulation

Electric vehicle (EV) is an important part of strong smart grid and low-carbon transport. In this paper, the power demand characteristics of different charging modes are analyzed first, the charging load model is constructed correspondingly based on Monte Carlo simulation. Taking the typical daily load profile of Shanghai for example, the charging curves of EVs are calculated and the impact on the load profile is studied. Result shows that charging modes have big effect on the charging load model of EV, and battery swapping mode could cut down the peak-valley difference in a great extent, which can improve the utilization and operation of power grid greatly.
