Master-slave game scheduling strategy for power grid operator and electric vehicle cluster

Abstract

The invention aims to ensure the stability of a whole power grid under V2G regulation and control configuration and also consider the rights and interests of common electric vehicle users while popularizing a V2G technology in order to overcome the defects and deficiencies in the prior art, thereby reducing the loss of batteries. According to a master-slave game scheduling strategy for the power grid operator and the electric vehicle cluster, the electric vehicle users form a cluster, take the minimum total charging cost as the goal, after multiple games, reaches the Stackelberg equilibrium finally. According to the present invention, by utilizing the technical scheme, and utilizing the characteristic that an electric vehicle can be charged and discharged, a reasonable charging and discharging strategy is formulated, so that the electric vehicle and an energy storage device achieve the effect of helping the power grid to cut peaks and fill valleys together while meeting the charging requirements, and the power grid operators and an electric vehicle users can obtain better economic benefits, and especially, the rights and interests of the electric vehicle users are guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a charging scheduling method for electric vehicles. Background technique [0002] With the rapid development of the economy, the problems of resource scarcity and environmental pollution are becoming more and more serious. Electric vehicles are becoming the main development direction of the automobile industry because of their energy-saving and environmental protection features. With the support of national policies and the active participation of major automobile manufacturers, the technical level of electric vehicles is increasing day by day. But the current huge automobile market is exacerbating the consumption of resources, and it also puts more pressure on urban energy. In this process, the charging of electric vehicles has become an important load borne by the grid, but electric vehicles can also be used as a power source to feed back to the grid, thereby helpin...

Problems solved by technology

[0003] However, most of the V2G technologies in the existing technology are planned from the perspective of the power grid. During this process, users cannot freely choose to use electric vehicles.

If electric vehicles are forced to use, not only will it cause fluctuations in the grid, but it may also cause damage to the batteries of electric vehicles
