Following the increase of number and total capacity of hydropower plants in power systems, the optimization of large-scale hydropower system operations is becoming more and more difficult because of more constraints and more complicated requirements involved. It is necessary to find the scientific, effi- cient, and practical optimization solution methods for these complicated problems. In this paper, a general solution framework for large-scale complex hydropower system operations is presented. It mainly consists of the intelligent solution strategies to reduce problem size, the combined methods to deal with curse of dimen- sionality, and the interactive visualization techniques to guarantee practical resuhs. Furthermore, these ap- proaches and strategies are tested by two practical hydropower systems, one is the long term operations of hydropower systems in the Yunnan Power Grid with 20 plants, another is the short term operations of hy- dropower systems of the Hongshuihe Basin in main stream with 9 plants. The proposed solution methodolo- gy will play an important role in developing hydropower system optimization platform for Smart Grid.
