The accuracy of long-term wind power forecasting (WPF) is crucial for the efficient operation grid systems. However, generation highly stochastic and intermittent due to influence weather, which makes WPF less effective. Numerical weather prediction (NWP) data contains valuable forecast information, can mitigate negative effects fluctuations on WPF. NWP decreases over time, multiple have redundancy errors that make it challenging extract valid information. Reducing variety in using more...
