Short-term wind power forecasting method based on multi-scale feature fusion and multi-task learning
In order to solve the problem of high-complexity modeling for wind farm cluster power forecas-ting caused by high-dimensional meteorological features in wide-area spatial scale,a short-term wind power forecasting method based on multi-scale feature fusion and multi-task learning is proposed,in which,the multi-scale feature fusion realizes the feature fusion of global,cluster and station scales. The feature extraction modules are constructed from global,cluster and station perspectives respectively,and on the basis of global block-wise attention and dynamic hybrid sparse graph attention,the model complexity is reduced and the computational efficiency is improved. The cluster forecasting task is decomposed into three tasks of direct prediction,indirect prediction,and fused prediction,and the cluster forecasting is realized through multi-task learning. The proposed method is applied in a wind farm cluster of Jilin Province,and the results show that the proposed method can effectively improve the model computational efficiency and wind power forecasting accuracy.
