The invention discloses a multi-factor 
electrical load prediction method based on 
deep learning, and the method comprises the steps: firstly completing the acquisition and storage of data, including 
electrical load data and environmental influence data; preprocessing and standardizing the data based on abnormal 
data detection, autoregression interpolation and sequence data normalization of a k-proximity 
algorithm and an improved 
DBSCAN algorithm; then, propsing an improved CNN-LSTM 
electrical load prediction model, and firstly using a CNN 
feature extraction module to learn local features of input data; inputting the input data into an LSTM 
sequence learning model, and extracting 
sequence feature information of the input data; meanwhile, introducing a self-attention mechanism into the LSTM for learning features of a 
hidden layer of the LSTM, and extracting key features by distributing different attention weights, so that the final prediction precision is improved; and finally, predicting the electrical load. According to the invention, digital upgrading of a 
power grid can be promoted, personalized requirements of users are met, and industry 
correlation analysis, power generation dispatching, 
power consumption trend prediction, work and production resumption guidance and the like are realized.
