摘要：
Aiming at the problem of rough active power distribution method of wind farm cluster, a three-layer adopting wind power cluster distribution layer, wind farm distribution layer and wind turbine distribution layer active power distribution method of wind farm cluster based on wind speed prediction information and clustering analysis is proposed. Among them, the cluster layer uses wind speed prediction information of wind farms to calculate the available power, and distributes the active power reference value of the cluster according to the proportion of the power that can be generated to realize the fair distribution of various wind farms. The wind farm layer classifies wind turbines (hereinafter referred to as "Turbine") by fuzzy c-means clustering method according to the fatigue loads generated by low-speed shaft torque and tower cylinder bending moment of the turbines, and distributes the power reference values of all types of turbines by priority ordering method. Aiming at the minimum of different fatigue loads of various turbines, the layer of turbine uses the quadratic programming algorithm to calculate the power reference value of the unit in real time to minimize the overall fatigue loads of the turbine. The feasibility of the proposed method is verified by an example analysis. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
