Disturbance-aware spatiotemporal feature fusion for wind power forecasting
摘要
To address the strong non-stationarity of wind power sequences and the complex mechanisms of disturbance propagation, existing studies on wind power forecasting often struggle to simultaneously capture time-varying spatial disturbance propagation and multi-scale temporal dependencies, leading to limited performance under non-stationary fluctuations and long-horizon forecasting scenarios. To this end, this paper proposes a multi-turbine wind power forecasting approach that integrates dynamic disturbance awareness with spatiotemporal feature modeling. Specifically, we first construct a disturbance-mechanism-driven dynamic adjacency matrix that jointly accounts for inter-turbine geographical proximity, wind-direction relationships, wake effects, and turbulence intensity, thereby dynamically characterizing the structural evolution of disturbances across the wind farm. We then employ a graph neural network composed of GraphSAGE and GAT to extract structural dependencies among turbines for spatial modeling, while introducing TimesNet for multi-scale temporal representation learning. Finally, spatiotemporal features are fused to perform wind power prediction. Experimental results demonstrate that the proposed method consistently outperforms multiple competitive baselines in both single-step and multi-step forecasting tasks and maintains higher stability and generalization capability under longer forecasting horizons.
