Accurate forecasting of wind speed and wind power is important for the safety of renewable energy utilization. Compared … wavelet and classical time series analysis, a new short-term forecasting method is proposed. Simulation upon actual time data … shows that: (1) the mean relative error in multi-step forecasting based on the proposed method is small, which is better …
