Hydro-dominated power grids such as Sichuan and Yunnan in China face many new problems in power generation scheduling that have not been encountered in the small- and medium -sized hydropower systems. This brings great challenges to the safety and efficiency of power system operations and large-scale absorption of clean energy such as hydropower. Sichuan Power Grid whose hydropower capacity ranks first in the country is taken as the background. With its hydropower status and actual operation requirements, this study analyzes several main problems of hydro-dominated power system operations, including curse of dimensionality of large-scale hydropower plants, generation safety control of giant hydropower units, hydropower transmission and absorption in flood season, and coordinated operations of inter-provincial hydropower plants on main streams. With the theory of hydropower optimization and practical experiences, this study also puts forward appropriate suggestions and strategies.
