英文摘要： Over the past two decades for large-scale development of hydropower projects, the intensive commissioning periods of giant cascaded hydropower stations in southwestern China have been approaching. However, the operation of giant cascaded hydropower system brings novel demands and issues which are different from the problems in the small hydropower system, especially in short-term and real-time operations. It has severely restricted the operation of giant cascaded hydropower system, and has a direct impact on the safety of power grids and hydropower stations as well as energy saving issues and economical operations. The giant cascaded hydropower systems are facing many novel problems, such as peak load regulation of multi-power grids, high-headed vibration zones of multi-unit and zoning control. For solving these problems above, the purpose of our research is to find a feasible and effective solution to the complex problems based on the view of "modeling and solving methods of optimal operation", and build the control-strategy of short-term and real-time operations through research and simulation analysis. The study is based on the projects of cascaded hydropower stations on Wujiang River, Hongshui River and Lancang River. The results with theoretical and practical significance are expected, which can be applied
