Abstract

The invention discloses an electric vehicle ordered charging coordination control method suitable for a plurality of charging stations. Firstly, each charging station calculates a set charging requirement boundary curve of all electric vehicles in the charging station according to charging requirement information and battery information of all the electric vehicles in the station and sends the set charging requirement boundary curve to a control center; then the control center calculates the optimal charging load guide curve of each charging station according to the set charging requirement boundary curve of all the electric vehicles in the station, which is reported by the charging station, electricity price of a power grid and electric vehicle charging load constraint conditions of a system and issues the optimal charging load guide curves to the corresponding charging stations; and each charging station adopts a coordinative optimization charging algorithm to calculate the optimal charging strategy of each electric vehicle in the station, so that ordered charging coordination control among a plurality of charging stations is implemented. The control method depends on an optimization model simple to calculate, has high calculating efficiency and has low requirements on the hardware environment of a control system; and communication resources between each charging station and the control center are effectively saved.

Description

technical field [0001] The invention belongs to the field of orderly charging control methods for electric vehicles at multiple charging stations, and in particular relates to a coordinated control method for orderly charging of electric vehicles applicable to multiple charging stations. Background technique [0002] In recent years, under the background of environmental pollution, increasing greenhouse benefits, and depletion of fossil energy, the potential of electric vehicles for energy saving, environmental protection, and emission reduction has been generally optimistic by governments around the world. In China, the government has issued corresponding incentive policies to vigorously promote the development and market popularization of electric vehicles. It can be expected that with the increasing maturity of electric vehicle technology and market popularization in the future, a large number of electric vehicles will be connected to the grid for charging, which will bri...
