Multivariable prediction method fusing population and electrical load

The invention discloses a multivariable prediction method fusing population and electrical load. The multivariable prediction method comprises the following steps: S1, obtaining population flow data, day granularity electric quantity prediction data and meteorological data; s2, carrying out feature division on all data, and constructing a data set available for the prediction model; s3, performing data division based on the prediction period, and selecting a training set, a test set and a verification set; s4, based on the population flow data set, the input features and the output features, modeling is performed through a tree model, a Prophet model and a multiple linear regression model, a population flow prediction result is obtained, and polarity linear fusion is performed on the population flow prediction result; and S5, based on the electricity consumption data set, the population flow prediction result and the meteorological data, performing modeling through a tree model, a Prophet model and a multiple
