To enhance the accuracy of ultra-short-term multi-step wind power forecasting
this study proposes a novel model that integrates improvements in the loss function with a patch-based temporal Transformer network. Specifically
an image-based anomaly detection and cleaning algorithm is firstly employed for data preprocessing
thereby enhancing the quality of the wind power data. Subsequently
to improve the robustness of the Transformer architecture and to strengthen its ability to capture local sequential dependencies
a patch module and a channel-independent strategy are incorporated into the standard Transformer framework. Finally
a novel multivariate nonlinear loss function is designed to effectively filter noise and to enhance the model's sensitivity to shape variations during sequence prediction. Extensive experimental results demonstrate that the proposed approach significantly outperforms several baseline models across multiple error metrics
thereby achieving substantial improvements in ultra-short-term multi-step wind power forecasting accuracy.
