Abstract

The invention provides an electric vehicle charging distribution method and apparatus. The method comprises the steps of establishing a charging uniform distribution target function by utilizing a charging station quantity, target charging power of the charging stations, an electric vehicle quantity, electric vehicle charging power, charging decision variables, charging journeys and charging time when a plurality of electric vehicles are distributed to a plurality of charging stations for charging; establishing constraint conditions of the charging decision variables and the charging journeys; under the constraint conditions, solving the charging uniform distribution target function by utilizing a basic particle swarm optimization algorithm to obtain charging decision results of the electric vehicles, wherein the charging decision results are used for distributing the electric vehicles to the charging stations for charging. According to the method and the apparatus, the demands of electric vehicle users and stable operation requirements of a power network can be met at the same time.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for charging and distributing electric vehicles. Background technique [0002] The large-scale commercial development of electric vehicles is an effective means to respond to the national energy conservation and emission reduction policies and increase the proportion of electric energy consumption and use in terminal sources. However, the application of new technologies will bring new opportunities and challenges to the grid. As a load that can be moved, the disorderly charging behavior of large-scale electric vehicles in time and space will not only cause the phenomenon of "peaks on top of peaks" in the power load, increase the peak-to-valley difference of the power grid, and may cause local overload, line Congestion and other issues will affect the stable operation of the power grid. At the same time, disorderly charging behavior will also cause cha...
