The fluctuation of wind power affects the operating safety and power consumption of the electric power grid and restricts the grid connection of wind power on a large scale. Therefore, wind power forecasting plays a key role in improving the safety and economic benefits of the power grid. This paper proposes a wind power predicting method based on a convolutional graph attention deep neural network with multi-wind farm data. Based on the graph attention network and attention mechanism, the method extracts spatial-temporal characteristics from the data of multiple wind farms. Then, combined with a deep neural network, a convolutional graph attention deep neural network model is constructed. Finally, the model is trained with the quantile regression loss function to achieve the wind power deterministic and probabilistic prediction based on multi-wind farm spatial-temporal data. A wind power dataset in the U.S. is taken as an example to demonstrate the efficacy of the proposed model. Compared with the selected baseline methods, the proposed model achieves the best prediction performance. The point prediction errors (i.e., root mean square error (RMSE) and normalized mean absolute percentage error (NMAPE)) are 0.304 MW and 1.177%, respectively. And the comprehensive performance of probabilistic prediction (i.e., continuously ranked probability score (CRPS)) is 0.580. Thus, the significance of multi-wind farm data and spatial-temporal feature extraction module is self-evident.
