Embodiment Construction
[0153] The technical solution of the present invention will be further described in detail below through the drawings and embodiments.
[0154] The invention provides a wind field equivalent modeling and optimization control method based on a fuzzy c-means clustering algorithm, such as figure 1 As shown, the method includes the following steps:
[0155] Step 1. Determine the number of clusters in the clustering algorithm according to the distribution of wind turbines in the wind farm;
[0156] Step 2. Select six characteristic values of output power average value, output power standard deviation, inertial time constant, longitude, latitude and altitude of wind turbines as the clustering elements in the clustering algorithm for analysis;
[0157] Step 3. Preprocess the average output power, standard deviation of output power, inertia time constant, longitude, latitude, and altitude of the wind turbine to obtain the characteristic matrix of the wind turbine;
[0158] Step 4. Determine ...
