Problems solved by technology

[0005] At present, the domestic and foreign research on the orderly charging of electric vehicles mainly focuses on the centralized charging control of vehicles. There are few studies on how to decompose the charging strategy results at the regional grid level to each electric vehicle.

Embodiment Construction

[0035]The description of the following embodiments refers to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.

[0036]Please refer tofigure 1 As shown, the embodiment of the present invention provides an electric vehicle charging load distribution method, including:

[0037]Step S1: Divide a day into multiple time periods at a set interval according to the input raw data for distributing the electric vehicle charging load, and obtain the historical charging power of each time period;

[0038]Step S2, determining the charging priority of the electric vehicle according to the collected electric vehicle data and the setting data input by the user;

[0039]Step S3: When there is no dispatch demand from the power grid during the current period, all electric vehicles are connected to the power grid for charging; otherwise, go to step S4;

[0040]Step S4, traverse the information of each electric vehicle user, if the user is unwilling to acce...

Abstract

The invention discloses an electric vehicle charging load distribution method, and the method comprises the steps: formulating an overall ordered charging plan of an electric vehicle according to thepower utilization characteristics of a non-flexible load and the commuting rule of the electric vehicle; furthermore, the travel habit, charging preference, mileage anxiety and other information of each user are comprehensively considered, and the charging load is fairly and reasonably distributed among the electric vehicles. When the charging requirement is met, the starting frequency of the charging process of the electric vehicle can be reduced, and the service life of the battery is maintained; under the condition of respecting the autonomous response of an electric vehicle user, the charging load distribution strategy in each time period is closely related to the inherent parameters and power utilization characteristics of the electric vehicle, and the orderly charging load of the electric vehicle can be reasonably regulated and controlled.

Description

Technical field[0001]The invention relates to the technical field of intelligent control of electric vehicles, and in particular to a method for distributing charging loads of electric vehicles.Background technique[0002]The emergence of the energy crisis and the development of various electric vehicle technologies have promoted the large-scale promotion of electric vehicles. Today, all countries are stepping up policy support for electric vehicles. It can be expected that a large number of electric vehicles will be connected to the grid in the future. After large-scale electric vehicles are connected to the grid, the economic benefits caused by electric vehicles and their impact on the planning and operation of the power system cannot be ignored.[0003]If the charging behavior of electric vehicle users is not guided and controlled, the disorderly charging of electric vehicles will result in "peak-plus-peak" to the original load of the power grid, affecting the safe and stable operati...
