The invention discloses a short-term and medium- and long-term
electric power load prediction method based on
machine learning model. Firstly, preprocessing is conducted on data, including smootheningabnormal data and filling
missing data. Factors of affecting load changes will be analyzed, including historical data, time periodicity, and weather variable characteristics.
Domestication will be conducted on all input variables for accelerating learning speed and raising prediction precision. The invention is advantageous in that
linear regression is compared, and the performance of the vectorregression and gradient lifting regression in the short-term and medium- and long-term
electric power load prediction is supported; with the
prolongation of the prediction time, the performance of thegradient lifting regression model is better that that of the other two models; the
AdaBoost algorithm which uses the gradient lifting tree as a basic classifier is brought forward, and load prediction is conducted, and the precision of
electric power load prediction can be effectively raised.
