This invention discloses a load time-series prediction method and system combining multi-scale slicing and masking. The method first preprocesses historical endogenous power load sequence data, historical exogenous covariate data, and exogenous covariate data to obtain preprocessed historical endogenous sequence data and multidimensional exogenous covariate data. Next, the preprocessed data is input into an endogenous multi-scale feature embedding module and an exogenous encoder, respectively, to extract multi-scale endogenous features and high-dimensional exogenous semantic features. Then, the multi-scale endogenous load features are fed into a fusion model to obtain a query vector, which, along with the high-dimensional exogenous semantic features, is input into an exogenous cross-attention module to generate the final fused features. Finally, the final fused features are passed through a feedforward network and a projection output layer to generate the power load prediction result for the future target time window. This invention solves the time alignment problem of heterogeneous exogenous power data and significantly improves the generalization and modeling capabilities for complex power grid dynamics.
