Abstract
Reasonable allocation of flood control capacity is associated with flood control safety, which is very important. A model for the optimal operation of multiple reservoir system considering the reserve demand of flood control capacity is proposed in this paper. The model takes into account the complex equality and inequality constraints during optimal operation process. The dynamic programming-progressive optimality algorithm (DP-POA) is adopted to solve the proposed optimal operation model. The multiple hydropower reservoirs in the lower reaches of Jinsha River in the upper Yangtze River in China is selected as a case study. The results show that DP-POA can fully take advantage of the flood control capacity such that the reserve demand of flood control storage is met in certain periods. In addition, the multiple hydropower reservoirs cooperates with each other to maximize the hydropower generation under the condition of reserve flood control capacity. The calculated total reserve flood control storage exceeds the preset values 35 × 108 m3, and the maximum hydropower generation of multiple reservoir system is 507.27 × 108 kWh. Thus, this paper provides a novel optimization strategy for the optimal allocation of multiple hydropower reservoirs.
