Embodiment Construction

[0034] Such as figure 1 , 2 As shown, a method of electric vehicle charging load distribution based on user wishes and travel rules includes dividing a day into 96 time periods, that is, the time interval is 15 minutes. The load data and the connection of electric vehicles to the grid are optimized by the power company online in real time, and the overall orderly charging plan for electric vehicles is formulated to obtain the ideal charging power for each time period. Collect electric vehicle data and user input related settings. Electric vehicle data includes the mileage and historical travel mileage that can be exercised under the current state of charge of the electric vehicle; user input related settings, including whether they are willing to participate in the scheduling plan, the expected residence time of the electric vehicle, Desired final state of charge of the electric vehicle and planned trip for the next day.

Abstract

The invention discloses an electric car charging load distribution method based on user will and the out-going rule. The method comprises the steps of obtaining ideal charging power of each time frame according to input original data for distributing electric car charging loads, determining weighting coefficients according to the collected electric car data and setting input by users, when the current actual maximum charging power of an electric car meets a system scheduling command, conducting traversal on information of each electric car user, accepting scheduling, participating in the optimization process, building a mathematical model for charging load distribution, and outputting the result. The frequency of starting and stopping charging of the electric cars can be reduced while the charging requirement is completed, on the premise of respecting the electric car users, the charging load distribution strategy in each time frame is closely connected with the characteristics of the electric cars, and the charging order of the electric cars can be fairly and reasonably arranged.

Description

technical field [0001] The invention belongs to the technical field of intelligent control of electric vehicles, and in particular relates to a charging load distribution method for electric vehicles based on user wishes and travel rules. Background technique [0002] The emergence of the energy crisis and the development of various technologies for electric vehicles have promoted the large-scale promotion of electric vehicles. Now, countries are stepping up their efforts to provide 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 cause "peak-on-peak...
