Abstract Wind power resources in China are mainly concentrated in the west and north.Large-scale wind power delivery is an effective way to solve the problem of wind power consumption.But with the increase of wind power penetration,the uncertainty caused by the power fluctuation enables that the automatic generation control (AGC) under some regions or provinces appears more serious problems,e.g.insufficient adjustable resources and control.To solve the problem,this paper uses the AGC units distributed in the whole network to achieve the optimal coordinated and distributed control.First,this paper introduces the concept of the coordination factor to establish the optimal coordinated AGC control model.Second,by using the original dual gradient algorithm to transform the model and the linear transformation method,the optimal coordination controller based on a distributed coordination factor is constructed.The simulation examples show that the grid dispatching AGC units can control the frequency deviation in coordination with the increase of the wind power penetration and effectively balance the amount of power imbalance caused by wind uncertainty.

Key words： Distributed optimal coordinated control large-scale wind power automatic generation control frequency control
