Aiming at the problem that the prediction accuracy of fluctuation data intervals and abrupt data points near the local peak value of traditional wind power prediction methods is limited
an ultra-short term wind power prediction method based on BiTCN-Informer fusion of temporal and spatial characteristics is proposed. Firstly
bidirectional temporal convolutional network (BiTCN) is used to analyze the information features of past observations and future covariates
and to extract the spatial features of the data. Then
the Informer probabilistic sparse self-attention mechanism and self-attention distillation mechanism are used to simplify the network parameters
reduce the computational complexity
identify the dependency relationship of long sequence data
and capture the temporal features of the sequence. Finally
a fully connected layer is introduced to integrate temporal and spatial features. The results of the case study show that the proposed combined model can effectively improve the prediction accuracy compared with other models.
