[0047] The above is only an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0048] Such as figure 1 As shown, the wind power prediction method based on history segmentation sequence search and time series thinning according to the present invention, the method comprises the following steps:
[0049] Step A. Normalize the historical wind power data of the wind farm, and determine the optimal value of the window width of the searched segmental time series according to the fluctuation characteristics and basic statistical characteristics of the wind power time series of the wind farm.
[0050] The historical time series of the original wind power of the wind farm is normalized to the [0,1] interval according to the following formula:
[0051]
[0052] I...
