Review on Optimal Operation Models and Intelligent Solving Algorithms of Cascade Hydropower Stations

The optimal operation of cascade power stations is not only one of the main development directions for the comprehensive exploitation, utilization and management of water resources, but also an important strategic direction for the sustainable development of national energy. This article starting with the overview and composition of the cascade power station group, expounds the operation characteristics and task requirements of cascade hydropower under different time scales, and provides a comprehensive overview of the objective functions and constraints of medium and long-term scheduling, short-term scheduling, and day-ahead scheduling. Then this article analyzes and compares the current intelligent solution algorithms for optimal operation of cascade hydropower stations at home and abroad, and finally gives an outlook on the future research about the participation of cascade hydropower in the electricity market.
