Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0068] In this embodiment, taking the Shandong power grid connected with large-scale electric vehicles in 2030 as an example, starting from the analysis of the impact of electric vehicles on the distribution network in Shandong, the implementation of the orderly charging control method in the present invention is introduced.

[0069] Starting with the charging behavior, it is divided into two categories: commercial vehicles represented by buses and passenger vehicles dominated by private cars. The charging behavior and mileage of the former are similar, and they are relatively orderly, and it is easy to realize time regulation; the use and charging of the latter are more random and flexible. Combined with the actual situation in Shandong, buses and private cars will be taken as typical research objects in this embodiment.

Abstract

The invention discloses a control method for ordered charging of an electromobile. The control method comprises the following steps of firstly, establishing a charging load characteristic model of the electromobile by integrating factors of battery characteristics, a charging mode and behaviors and habits of users; secondly, with the goal of minimizing the difference between the peak and the valley of a load, establishing a centralized optimization model according to the minimal variance of load demands at all time intervals and the average load level, enabling the load fluctuation to be minimized, and realizing the stabilization of the load to obtain reference optimized power; thirdly, establishing a distributed optimization model, and optimizing an individual charging scheme according to the reference optimized power obtained by a power grid and a middle manager in the optimizing process of the second step and dynamic electricity price in 24 hours. A cooperative control model is established by adopting a centralized and distributed combined optimized control idea, so that the negative effect of large-scale disordered charging of the electromobile on planning and operation of the power grid is reduced.

Description

technical field [0001] The invention relates to the technical field of charging control of electric vehicles, in particular to a method for controlling orderly charging of electric vehicles. Background technique [0002] In order to reduce greenhouse gas emissions and dependence on oil imports, large-scale development of electric vehicles and the realization of electricity instead of oil on the user side have become the main solution at present. With the large-scale access of electric vehicles, it is bound to have an impact on the planning and operation of the power grid. Uncontrolled disorderly charging will pose a serious threat to the safety and economic operation of the power system. [0003] Electric vehicles have dual characteristics of load and power supply, making them an important means of power grid regulation. Utilizing peak-valley time-of-use electricity prices to guide users to charge at low-valley times has a certain effect on peak-shaving and valley-filling,...
