Accurate wind power forecasting is crucial for the reliability of grid scheduling decisions. To address the variability in wind power output
a wind power online forecasting method based on dynamic deep learning is proposed. Initially
a benchmark model utilizing bidirectional Long Short-Term Memory(LSTM) networks and bidirectional Gated Recurrent Units(GRU) is developed
with parameters and weights tailored to the training dataset. Subsequently
a fast Hoeffding drift detection method is used for wind power state monitoring
and the deep learning model is dynamically updated based on the detection results. Finally
a Random Forest regression model is integrated to correct the predicted power errors
enabling rolling online forecasting through sequential time windows. Validation results indicate that the proposed algorithm improves the root mean square error(RMSE) by 5.68%
the mean absolute error(MAE) by 18.56%
and the coefficient of determination() by 2.06% compared to the Transformer
demonstrating good predictive performance and further enhancing the accuracy of wind power forecasting.
