| Summary: | To address the challenges of existing power load forecasting models， which struggle to deeply extract spatiotemporal correlation features and exhibit weak generalization capabilities—failing to simultaneously manage both short-term and long-term forecasting—this study proposes a multi-user power load forecasting method using cosine similarity and a global-local collaborative graph convolutional network. First， cosine similarity is utilized to learn similar patterns between load data from different nodes， allowing for the deep extraction of spatiotemporal correlation features. Second， a collaborative modeling approach is applied to static global factors and dynamic local factors that influence power load trends， enhancing the model’s generalization ability. Finally， extensive experiments on a real-world dataset demonstrate the method’s effectiveness and robustness in forecasting both short-term and long-term load series. |
