Research and design of orderly charging strategy for integrated energy charging station
With the development of electric vehicles, there are more and more charging users. Meanwhile, there are a series of problems, especially the high charging cost, long charging queue time and power grid load safety impact brought by disordered charging, which restrict the development of electric vehicles and charging facilities. To solve such problems, this paper studies and designs orderly charging strategy. By studying the charging process data of electric vehicles, the relationship curves of charging voltage, current, SOC and charging time are analyzed, and the reasonable SOC value of stopping charging is formulated in different electricity price periods and the situation of more vehicles and less piles. In order to improve the operation income of charging stations, the power limiting and orderly charging strategies of different charging piles are designed according to the different vehicles served by charging stations. The implementation of charging station orderly charging strategy can improve the operation income, reduce the cost, make the charging time more reasonable, improve the charging experience, make the charging station interact with the power grid, conduct the peak-load shaving, reduce the load fluctuation rate, and improve the security of the power grid.
