Energy Management Of Electric Vehicles Based On Demand Side Management

With rapid development of electric vehicle industry and construction of charging pile, charging station and battery swapping station, the relationship between electric vehicles and power grid are getting more and more complex. Therefore, how to avoid the negative influence caused by randomly charging and discharging power after extensive electric vehicles accessing to grid and effectively use large-scale energy storage effect have become an urgent problem.Consequently, an attempt is adopted to solve the problems mentioned above by studying the clustered model and energy management of large-scale electric vehicles to grid.Firstly, based on the analysis of mode and characteristic of electric vehicles’ charging and discharging, the load characteristics of electric vehicles in different charging and discharging mode is analyzed; Secondly, demand side management is used to induct electric vehicles’ charging and discharging behaviors, so as to achieve the complementary synergy between electric vehicles and other power sources with different characteristic; Lastly, time of use price is used to manage the load of charging pile in order to guide electric vehicle orderly charged and discharged.
