[0036] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and examples.
[0037] A WRF model wind speed correction method based on self-similarity proposed by the present invention, the overall technical roadmap is as attached figure 1 As shown, consists of 3 steps:
[0038] I. Calculate the self-similarity index α of the historically observed wind speed in the target area;
[0039] II. Establish a WRF real-time forecast system for the target area;
[0040] III. Establish a revision module.
[0041] Described step 1 comprises:
[0042] (1) Extract the fluctuation structure in the historical observation wind speed time series of the target area;
[0043] (2) Calculate the linear slope k and time scale δt of the historical wind speed fluctuation structure;
[0044] (3) Determine the actual self-similarity index α of the wind speed in the target area.
