Abstract

The present invention provides a method for evaluating the changes in the hydrological situation during the day of the integrated operation of water, wind and solar power in a river basin, comprising the following steps: combining the hydrological characteristics of the river basin and the reservoir scheduling mode, determining the scheduling period after the water, wind and solar power in the river basin participate in the operation, and for each scheduling period, determining the evaluation benchmark period when the corresponding water, wind and solar power in the river basin do not participate in the operation; evaluating and obtaining the hydrological situation change degree and hydrological morphological change degree of the daily hydrological situation evaluation index during the scheduling period, thereby obtaining the comprehensive change degree of the daily hydrological situation. The method for evaluating the changes in the hydrological situation during the day of the integrated operation of water, wind and solar power in a river basin provided by the present invention can comprehensively and accurately evaluate the impact of the scheduling of hydropower stations on the daily hydrological situation of rivers, provide a scientific basis for the ecological scheduling of hydropower stations, and help achieve the harmonious development of hydropower stations and the ecological environment.
