In recent years; clean energies; such as wind power have been developed rapidly. Especially; wind power generation becomes a significant source of energy in some power grids. On the other hand; based on the uncertain and non-convex behavior of wind speed; wind power generation forecasting and scheduling may be very difficult. In this paper; to improve the accuracy of forecasting the short-term wind speed; a hybrid wind speed forecasting model has been proposed based on four modules: crow search algorithm (CSA); wavelet transform (WT); Feature selection (FS) based on entropy and mutual information (MI); and deep learning time series prediction based on Long Short Term Memory neural networks (LSTM). The proposed wind speed forecasting strategy is applied to real-life data from Sotavento that is located in the south-west of Europe; in Galicia; Spain; and Kerman that is located in the Middle East; in the southeast of Iran. The presented numerical results demonstrate the efficiency of the proposed method; compared to some other existing wind speed forecasting methods. © 2020 Elsevier Ltd;
