Power demand prediction method and device based on association graph, equipment and storage medium

The invention relates to a power demand prediction method and device based on an association graph, equipment and a storage medium, and the method comprises the steps: obtaining an industry power consumption association model based on the industry power consumption; solving the industry power consumption correlation model by adopting a target function to obtain a power demand influence factor matrix corresponding to the industry power consumption correlation model; processing the power demand influence factor matrix to obtain an industry power consumption incidence matrix; based on the industry power consumption incidence matrix, determining an industry power demand incidence diagram; and screening out a target industry reflecting a power demand change trend according to the industry power demand association diagram. The data accuracy of the screening result of the leading industry of the power demand can be improved, and the processing efficiency of the industry power consumption data can be effectively impr
