Embodiment Construction

[0022] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings. It should be noted that: based on the perspective of the load aggregator, the present invention will mainly solve the acquisition of the charging control strategy vector at the L2 layer (local energy management layer) and the calculation method of the suggested cooperation degree at the L3 layer (user equipment layer). The peak-shaving incentive or time-of-use electricity price setting scheme of the L1 layer (regional power grid management) is not within the scope of the present invention.

[0023] A distributed control method for orderly charging management of electric vehicle groups provided by the present invention mainly includes the following aspects:

[0024] [1] L2 layer: charging strategy vector p * the acquisition

[0025] The charging behavior of electric vehicles in a low-voltage distribution network is regarded as a no...

Abstract

The invention provides a distributed type management method for electric automobile group ordered charging management. The distributed type management method enables the power demand of a large-scale electric automobile group to be not exceed distribution network limit, and enough battery electric quantity can be obtained after a charging period; in the distributed type management method provided by the invention, the charging control is taken as a non-cooperative game between the electric automobile and the power distribution network, and the charging control has a weak-coupling cost function; the cost function of electric automobile charging comprises an individual cost item and a collective cost item that are used for representing demand will for charging the electric automobile to the required battery electric quantity and influence on the power distribution network by the electric automobile group charging process respectively; a simulation result shows that the distributed control method enables an electric vehicle user to reduce the charging cost; and meanwhile, the peak load of the power distribution network is effectively reduced, the load curve is smoothened, and the construction and investment cost of the power grid is reduced.

Description

technical field [0001] The invention relates to a distributed control method for orderly charging management of electric vehicle groups, belonging to the field of energy management. Background technique [0002] As an effective way to solve the shortage of traditional fossil energy, the aggravation of urban environmental pollution, and global warming, electric vehicles (Electric vehicles, EVs) are receiving widespread attention around the world. The focus of consumers' attention. In the "Energy Saving and New Energy Vehicle Industry Development Plan (2012-2020)" issued by the State Council, it is clearly stated that "by 2015, the cumulative production and sales of pure electric vehicles and plug-in hybrid vehicles will strive to reach 500,000; by 2020 , the production capacity of pure electric vehicles and plug-in hybrid electric vehicles will reach 2 million, and the cumulative production and sales will exceed 5 million". [0003] The impact of the rapid growth of electri...
