Abstract Given the volatility and randomness of wind power, a model for short term wind power forecasting which utilizes secondary mode decomposition and an secretary bird optimization algorithm (SBOA)-optimized temporal convolutional netwaork (TCN)-bidirectional gate recurrent unit (BiGRU)- Attention mechanism to enhance prediction accuracy. Firstly, complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and variational mode decomposition (VMD) algorithms are applied for secondary mode decomposition of the wind power time series. Secondly, the decomposed sub-series are fed into the SBOA-TCN-BiGRU-Attention network for combined prediction, with the SBOA optimizing the neural network's hyperparameters to avoid local optima. Finally, the predicted values of the sub-series are aggregated to derive the final result. The simulation findings indicate the proposed combined forecasting method predicts short term wind power with high accuracy.
