Short-term Wind Power Forecasting Based on BWO‒VMD and TCN‒BiGRU
Published 2025-05-01“…In addition, experiments are conducted not only on the main dataset but also extended to January and August data, which represent seasonal differences, for generalization to verify the re-liability and broad applicability of the model. The verification results indicate that the constructed model effectively handles various datasets and complex time series features, with strong robustness and generality, and can run stably and efficiently in various practical scenarios.ConclusionsThe decomposition of raw wind power data is primarily examined using the OVMD algorithm in this study. …”
