Research of Hydropower Stations Optimal Operation Based on the Discrete Differential Dynamic Programming - Progressive Optimization Algorithm Combination Method

The progressive optimization algorithm over-depends on the initial state, it needs to assume certain different types of initial test strategies and corresponding initial test paths, the calculation process repeats 2 to 5 times. Considering the shortfalls mentioned above, this paper presents discrete differential dynamic programming-progressive optimum combination method which is applied in the operation of hydropower station and designs a solution based on the method to optimize the operation of hydropower stations. Calculation example shows that this method is effective, highly reliable in global optimization and full of prospects.
