Example Embodiment

[0084] The present invention will be further described below in conjunction with the accompanying drawings.

[0085] The specific implementation of the demand response-based economic dispatch method for electric vehicles depends on the understanding of the economic dispatch model framework. Research on the charging strategy of electric vehicles based on demand response, optimize the trigger value of charging electricity price for electric vehicle users according to the real-time electricity price information of the power grid, and reduce the charging cost of users. At the same time, the unit combination problem of power system including large-scale electric vehicles is studied. On this basis, an economic dispatch model of electric vehicles based on demand response is established. By predicting the behavior characteristics of electric vehicle users, with the goal of maximizing the revenue of the power grid company, the charging price of electric vehicles is optimized and the c...

Abstract

The invention discloses an electric vehicle economic dispatching method based on demand response. The electric vehicle economic dispatching method comprises the steps of firstly, outlining an economic dispatching model; secondly, proposing an electric vehicle charging strategy based on the demand response, optimizing a charging electricity price trigger value of electric vehicle users based on network real-time electricity price information, reducing charging cost for the users; meanwhile, studying an electric power system unit commitment containing large-scale electric vehicles; and on that basis, establishing an electric vehicle economic dispatching model based on the demand response through the prediction of behavioral features of the electric vehicle users. The invention is aimed at maximizing profits of grid companies, the charging electricity price of an electric vehicle is optimized, and the charging load of the electric vehicle can be shifted.

Description

technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof. More precisely, the invention relates to a method for economic dispatching of electric vehicles based on demand response. Background technique [0002] With the increasing energy and environmental crisis, electric vehicles have become one of my country's strategic emerging industries due to their advantages in energy saving and environmental protection. When large-scale electric vehicles are connected to the power grid, their disorderly charging and discharging behavior will have a profound impact on the planning and operation of the power system, bringing about many problems such as voltage drop, increased network loss, and harmonic pollution. In the context of the development of smart grid, proper charging control can not only suppress and eliminate the adverse impact of electric vehicles on the grid, but also support the operation of the grid, achieve peak...
