Problems solved by technology

Its shortcoming is that the optimization variable of the nonlinear mixed integer programming problem is proportional to the number of electric vehicles. Issuing different instructions separately has higher requirements for communication facilities

Embodiment Construction

[0034] The distributed joint coordinated control method for the charging load of large-scale electric vehicles proposed by the present invention has a flow chart such as figure 1 As shown, including the following steps:

[0035] (1) The client of the control system obtains the charging start time t from the user side respectively start And charging end time t end , Obtain the current battery capacity B and current battery state of charge SOC of the user's electric vehicle from the battery management system, and obtain the charging power P and the charging efficiency η of the charging pile from the charging pile control system;

[0036] (2) The client calculates the charging time of the electric vehicle based on the information obtained above And set the initial charging power of the electric vehicle to L 0,n (t), n=1,2,...,N EV ,T=1,2,…,T max , Where n is the client number, N EV Is the number of controlled electric vehicles, t is the sample number, T max Is the maximum sampli...

Abstract

The invention relates to a distributed uniting coordination control method of a large-scale electric automobile charging load, and belongs to the technical field of energy management. Client terminals determine and send the initial charging power to a coordination center according to basic information of an automobile. The coordination center calculates an optimized load curve and an optimized judging threshold value. A current load curve and a representation value of the current load curve are calculated according to the charging power of the client terminals. If the representation value is smaller than the judging threshold value, a stopping mutual order is sent, and the client terminals charge the electric automobile according to the charging power, and if not, a probability transfer matrix is calculated and is sent to the client terminals. The client terminals calculate a transfer matrix according to the probability transfer matrix, and the charging power is updated and sent to the coordination center. Interaction is executed repeatedly until the representation value is smaller than the judging threshold value. Staggering-peak charging can be effectively achieved, the calculating pressure of the coordination center is relieved, the charging demand privacy of a user is protected, the data communication resources between an upper layer and a lower layer are saved, and the distributed uniting coordination control method is suitable for orderly controlling large-scale electric automobiles.

Description

Technical field [0001] The invention relates to a distributed joint coordinated control method for a large-scale electric vehicle charging load, and belongs to the technical field of energy management. Background technique [0002] Compared with traditional cars, electric vehicles have the advantages of energy saving, environmental protection, low carbon emission reduction, etc., and have significant advantages in solving energy crisis and environmental pollution problems, and are favored by governments around the world. In China, the country vigorously promotes the development of the electric vehicle industry. In 2012, the State Council put forward the ambitious goal of "In 2015, the cumulative production and sales of pure electric vehicles and plug-in hybrid vehicles will reach 500,000, and by 2020 it will exceed 5 million". It is foreseeable that in the future when electric vehicles are widely popular, the access of their charging load will have a non-negligible impact on the ...
