生态流量约束下梯级水电站群补偿调度的模拟优化方法Simulation-Based Optimization Method of Compensative Operation for Cascade Reservoirs Considering Ecological Flow Constraint

Abstract: Given coordination problems between power generation and ecological flow regulation, a limited compensative operation method of cascade reservoirs was proposed. In this paper, total power generation of cascade reservoirs was decided by cascade storage energy. On the basis of maximizing cascade storage energy, a long-term optimal operation model was developed with maximizing energy production as the objective function and ecological flow as a constraint. The simulation-based optimization algorithm was adopted to optimize operation rules. And the ecological flow constraint was satisfied by regulating minimum release of each reservoir. The Lancang River cascade reservoirs were used as case study. Simulation results show that the proposed method can meet the requirements of ecological flow and maximize comprehensive benefits with reliable generation benefits.
