With the rapid development of wind industry in China,it plays an important role for the promotion of energy transition to exploit wind energy in a large-scale format. However,due to the complicated environment and high construction and operation cost,it faces a series of technical difficulties and challenges to develop the wind farms in the format of a cluster. In view of this,the prediction,planning,and control technologies related to the construction and operation of wind farm cluster are summarized in this paper. Specifically,the key technologies and research route of the wind farm cluster are summarized in this paper. According to the characteristics of the wind farm cluster,the quantitative characterization and prediction of wind resources,the coordinate optimal planning of multiple wind farms,and the control and operation of multiple wind farms are discussed in detail. The current research status and achievements in each technology field are analyzed in this paper. Lastly,the development trend of the construction and operation of wind farm cluster is illustrated and the technical difficulties to be addressed are pointed out in this paper. The summary of these technical research achievements can provide reference for the large-scale and clustered development of wind power in China.
