Abstract

The invention discloses a V2G control strategy for cluster electric vehicles. The V2G control strategy comprises that an equipment level hysteresis control model for a single electric vehicle is established; a status priority aggregative indicator of the cluster electric vehicles is put forward; and the V2G control strategy for the cluster electric vehicles considering the priority status of the electric vehicles is put forward. According to the V2G control strategy for the cluster electric vehicles, by controlling charging, discharging and closing states of the electric vehicles, load regulation of the cluster electric vehicles is achieved, participation in power system demand response is realized, and the target that the cluster electric vehicles can accurately and quickly track the power within the controllable capacity range and given by a power system dispatching mechanism is realized.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a V2G control strategy for cluster electric vehicles. Background technique [0002] In order to alleviate the increasingly prominent environmental and energy problems, the proportion of renewable clean energy such as wind power generation and photovoltaic power generation technology connected to the grid is increasing. It will be a very difficult and challenging task to effectively deal with the volatility introduced by large-scale new energy access to the grid. . In order to stabilize the negative impact of power fluctuations on the grid, it is necessary to increase the reserve capacity of traditional power generation units in the grid, which undoubtedly reduces the economic and environmental value of renewable energy. [0003] With the continuous development of smart grid technology, demand response (Demand Response, DR) is used to solve the problem of large-scale renewabl...
