Method and device for determining electricity consumption and electronic device

The invention provides an electricity consumption determination method and device and an electronic device, and the method comprises the steps: classifying first historical electricity consumption data according to features corresponding to the first historical electricity consumption data, and obtaining a classification result corresponding to the first historical electricity consumption data; at least inputting the multi-order connotation mode component of the first historical electricity consumption data into the initial self-attention mechanism model to obtain initial electricity consumption prediction data; determining a cross entropy loss function of the initial self-attention mechanism model until the cross entropy loss function converges, and determining the initial self-attention mechanism model corresponding to the convergence of the cross entropy loss function as a target power consumption prediction model; and inputting the third historical electricity consumption data into the target electricity
