Embodiment Construction
[0153] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0154] The present invention provides a wind field equivalent modeling and optimal control method based on the fuzzy c-means clustering algorithm, such as figure 1 As shown, the method includes the following steps:
[0155] Step 1. Determine the number of classes in the clustering algorithm according to the distribution of wind turbines in the wind field;
[0156] Step 2, select the output power average value, output power standard deviation, inertial time constant, longitude, latitude and height of the wind turbine as the clustering elements in the clustering algorithm for analysis;
[0157] Step 3, preprocessing the average value of output power, standard deviation of output power, inertial time constant, longitude, latitude and height of the wind turbine to obtain the characteristic matrix of the wind turbine;
