Optimal operation of the cascade hydropower station reservoirs in the upper Hanjiang River

According to the characteristics and main task of the hydropower station reservoirs in the upper Hanjiang River, the problem of long-term optimal operation for the cascade reservoirs is studied. Long-term optimal operation model is established with the target function of maximum cascade power capacity. The optimal model is solved with the combination of successive approximation method of dynamic programming and progressive optimal algorithm (referred as DPSA-POA). The results show that the optimal effect of is better than effects of other algorithms, which the power capacity of hydropower stations and water resources utilization rate increase obviously compared to the results of other algorithms.
