Multi-element load prediction method and device for regional integrated energy system, and storage medium

The invention discloses a multi-element load prediction method and device for a regional integrated energy system and a storage medium, and the method comprises the steps: (1) collecting the operation data and historical meteorological data of the regional integrated energy system as an original data set, carrying out the correlation analysis of electric, thermal and cold loads and meteorological factors through employing a Pearson's correlation coefficient PCC, and obtaining a data set; features with high correlation are screened out, and the screened data are preprocessed; (2) converting one-dimensional electric, thermal and cold load sequence data into a three-dimensional pixel matrix form; (3) according to the difference between the multi-element load and the meteorological data information value, extracting high-dimensional features by using an improved CNN and a full connection layer respectively, and then merging the extracted high-dimensional feature matrixes; (4) adopting a multi-element load predict
