Abstract Wind power has emerged as a successful component within systems. The ability to reliably and accurately forecast wind speed is of great importance in maintaining the security stability grid. However, significance explaining prediction models often been overlooked by researchers. To address this gap, study introduces novel approach forecasting that incorporates significant decomposition method, attention‐based machine learning, local explanation techniques. proposed model utilizes grid search variational mode decompose sequence into different modes while employing gate recurrent unit with an attention mechanism achieve superior performance. Experimental evaluations conducted on eight real‐world datasets demonstrate outperforms other popular across multiple performance criteria. In two specific experiments, achieved minimal mean absolute percentage error 2.74% 1.70%, respectively. Furthermore, interpretable model‐agnostic explanations (LIME) were employed assess influence factors, highlighting whether they positively or negatively affected predicted values.

This study proposes an effective wind speed forecasting model combining a data processing strategy, neural network predictor, and parameter optimization method. (a) Variational mode decomposition (VMD) is adopted to decompose the into multiple subseries where each contains unique local characteristics, all are converted two-dimensional samples. (b) A gated recurrent unit (GRU) sequentially modeled based on obtained samples makes predictions for future speed. (c) The grid search with rolling cross-validation (GSRCV) designed simultaneously optimize key parameters of VMD GRU. To evaluate effectiveness proposed VMD-GRU-GSRCV model, comparative experiments hourly collected from National Renewable Energy Laboratory implemented. Numerical results show that root mean square error, absolute percentage symmetric error this reach 0.2047, 0.1435, 3.77%, 3.74%, respectively, which outperform benchmark using popular methods, techniques, hybrid models.
