# 梯级水库防洪库容分配策略研究Storage Allocation Strategy for Flood Control of Cascade Reservoirs

Abstract: Due to the changes of flood control task and boundary condition of cascade reservoirs, a mathematical model was established to allocate cascade reservoir flood prevention storage. Coupled hydropower generation with flood control operation objections, progressive optimality algorithm was used to obtain Pareto non-inferior solutions of maximum hydropower generation under the minimum flood prevention storage constrains for cascade reservoirs. The Qingjiang basin was selected as case study, the optimal storage allocation strategy for the Shuibuya and Geheyan reservoirs was given. If the Shuibuya reservoir keeps 500 million m3 and Geheyan reservoir remains not less than 150 million m3 flood prevention storages, the maximum regulation water level of the Geheyan reservoir will not over 200mwhen 100-year flood occurs, which can assurance flood control safety. The proposed method might provide a new approach for cascade reservoir storage allocation.
