An error correction ACKLSTM model combining data-driven and deep learning for wind power prediction
This research introduces an advanced hybrid wind power prediction model, ACKLSTM, designed to enhance the accuracy and reliability of forecasting in renewable energy systems. By integrating a self-attention mechanism, ConvLSTM, and a novel Kolmogorov-Arnold Network (KAN) as the output layer, the model effectively captures complex temporal dynamics and nonlinear relationships in wind power data. Furthermore, an SVM-based error correction mechanism is incorporated to mitigate prediction errors, particularly under extreme weather conditions. Validated with real-world data from a wind farm in Hubei, China, the ACKLSTM model demonstrates superior performance over existing methods, achieving a significant reduction in prediction errors and improving overall forecasting stability and practicality.

Ablation Studies
Ablation experiments confirmed the effectiveness of both the error correction technique and the incorporation of KAN. KAN alone reduced parameters by ~10% and training time by ~25%, while error correction consistently improved accuracy across all baseline models, showing their complementary benefits.
Impact of KAN and Error Correction
Ablation studies reveal that integrating the KAN layer significantly reduces model parameters (~10%) and training time (~25%) compared to traditional MLPs, while enhancing prediction accuracy. The SVM-based error correction mechanism further contributes by effectively rectifying residual prediction errors. When combined, these elements yield the best overall performance, demonstrating a powerful synergy that balances computational efficiency with superior forecasting accuracy for complex wind power data.
- KAN: ~10% parameter reduction, ~25% training time reduction.
- Error Correction: Consistent accuracy improvement across baseline models.
- Combined: Achieves best overall performance, reducing MSE to 0.09100.
