Embodiment Construction
[0032] In order to overcome the deficiencies of the prior art, the present invention aims to propose a wind speed prediction method based on ensemble forecast data, which can better use the means of data mining and the results of ensemble forecast members to improve the accuracy of wind speed forecast. According to the 51 forecast members produced by the ensemble forecast product ECWMF for each forecast period, the CART pruning method is used to select the optimal members, and the optimal members are used to construct the GBDT model, and finally the wind speed prediction based on the ensemble forecast data is realized. For this reason, the technical scheme that the present invention adopts is, a kind of wind speed prediction method based on ensemble forecast data, and the steps are as follows:
[0033] (1) Preprocessing of ensemble forecast data
[0034] 1) Use the measured wind speed data of platform A in Bohai Bay to determine the wind speed tag data;
[0035] 2) Read out t...
