Electric vehicle economic dispatching method based on demand response

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...

Problems solved by technology

[0003] At present, most of the relevant research is based on the direct dispatch of electric vehicles as the basic assumption. In fact, the dispatching organization does not have this authority, and with the expansion of the scale of electric vehicles, the computational complexity of optimizing the charging strategy for electric vehicles will also increase. When the dispatching organization directly dispatches each connected electric vehicle in a unified manner, there may be problems of dimensionality disaster and excessive calculation time.
