A distributed control method for orderly charging management of electric vehicle groups

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 the majority of consumers. 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 ...
