Abstract: Wind power has become one of the essential solutions to renewable energy and sustainable development problems. The accuracy of wind speed forecasts primarily determines the utilization of wind energy. Because many factors affect wind speed, high-precision wind speed prediction is still a practical and challenging task. In this paper, we propose multidimensional spatial-temporal graph neural networks (MST-GNN) for wind speed prediction: (1) establish a transformer-based model named Wind-Transformer on temporal perspective for single-point wind speed prediction with multidimensional data (wind speed, wind direction, temperature, air pressure, etc.), (2) apply graph neural network using Wind-Transformer as a node on spatial view to accurately predict the wind speed at local point by comprehensively aggregating the wind speed of local point and surrounding points. Through comprehensive experiments on open source datasets for wind speed prediction, we demonstrate that our model MST-GNN outperforms the state-of-the-art baselines up to 8.96%. The longer the prediction steps, the more improvement relative to other methods.
