Short-term power load prediction method and system based on multi-load mode

The invention provides a short-term power load prediction method based on a multi-load mode. The short-term power load prediction method comprises the steps of obtaining load historical data of a prediction area; classifying the load historical data and forming a load curve of each load mode; carrying out intelligent segmentation on the load curve; constructing a prediction model of multiple modes, and respectively carrying out simulation prediction on each subsection load of each load mode; and screening out various load modes and load prediction models corresponding to the segmented load curves, and predicting the daily load curve with the prediction day to finish prediction of the daily load curve. The invention further provides a prediction system applying the method. The difference ofload curves of workdays, weekend days and major holidays is fully considered, and the to be predicted load areas are intelligently segmented, the load prediction model is selected according to different periods of time, the
