Bus load combined prediction method and system based on distribution factors and information entropy

The invention discloses a bus load combined prediction method and system based on a distribution factor and information entropy, and relates to the technical field of power grids. The method comprisesthe steps of determining a prediction day, and determining a similar day of the prediction day according to a load in a power grid; determining a distribution factor according to the historical dataof each type of load of the similar day; determining at least two prediction models, taking the prediction precision as a target attribute, determining a weight vector of each prediction model throughinformation entropy, and weighting each prediction model according to the weight vector to obtain a combined prediction model; and processing the historical data according to the distribution factor,and inputting the processed historical data into the combined prediction model to obtain a bus load prediction result of the prediction day. The invention is suitable for bus load prediction, improves the type load prediction p
