Abstract

Abstract:

Electric vehicle in the future large-scale promotion will have important impact on power grid, the electric vehicle charging load forecast is the basis of the analysis of electric vehicles connected to the electricity grid. By analyzing the influence factors of electric vehicle charging load, with the three types of private car, bus, taxi electric cars as well as the conventional charging and fast charging these two charging mode, the Monte Carlo method is used to draw different types of vehicles, range and different charging mode to start charging time, get initial charged state, calculate the charging time length, finally calculate the charging load, charging load curve, the calculation results for the research of electric vehicles and orderly charging strategy provides certain theoretical basis.

Key words: Electric vehicle, charging load, Monte Carlo simulation
