Аннотация: This article considers the problem of short-term forecasting of natural inflow a day ahead to the site of a hydroelectric power station. The publications review on the research topic, carried out in the first part of the article, substantiates the relevance of using machine learning methods for solving the problem of predicting HPPПоказать полностьюmodes. The second part of the article compares the accuracy of models based on linear and polynomial regression with models based on ensemble methods of machine learning, in particular, decision trees, random forest, gradient boosting of decision trees, single decision tree stacking and random forest. The site of the Sayano-Shushenskaya hydroelectric power plant is considered as an object of research. The calculation results presented in the article were obtained on the basis of retrospective information on the natural inflow to the HPP and meteorological factors for 4 years of observations with a discretization step of a day.
