As the important part of the inter basin water transfer project, the safety and risk problems of the cascade pumping system are outstanding. The key to solve the above problems is to achieve multi-objective optimal operation. This project combines the latest research progress at home and abroad and the actual demand of Miyun water project. Based on the previous work, we have carried out the hydraulic mechanism analysis of all the components and facilities of the cascade pumping system, such as pump, gate, canal and inverted siphon and so on. The mechanism of interaction between the components is analyzed, the dynamic change law of cascade hydropower system with multi-element coupling under different working conditions is revealed, a multi-objective optimization scheduling model based on security risks and economic benefits is built, and an efficient multi-objective solution method co-evolution with common belief space and the constraint processing strategy combining with boundary rebound are proposed and finally results in the realizing of the fine adjustment of the multi-level process of the cascade pumping system. This research is of great significance for developing the basic theory and technology of inter basin water transfer project, and it can provide basic scientific and technological support for solving the problem of safe and efficient operation of cascade pumping system in China. The prophase work base of the declaration team is solid, the personnel are reasonable and have good experimental conditions.
