Accurate power load forecasting is crucial for the operation and maintenance of low-voltage distribution areas. To improve the accuracy of power load forecasting

this paper proposes a low-voltage load forecasting model that integrates a crisscross optimization algorithm (CSO) with a convolutional block attention module (CBAM) and a temporal convolutional network (TCN). First

a forecasting model is established based on TCN to extract the implicit temporal patterns of the input sequence of power loads. Second

a CBAM module is introduced at the model input side to apply channel-wise and spatial-wise weighting

thereby enhancing the model’s sensitivity to key features. Finally

to address issues such as local optima and limited generalization

the CSO algorithm is proposed to perform secondary optimization on the fully connected layer of the CBAM-TCN model. Using real power load datasets from two typical low-voltage substations in Guangdong province for simulation and modelling

the results show that the proposed hybrid forecasting method outperforms other comparative models and effectively validates its superiority.
