防凌是寒冷地区水库调度的重要目标。将水库出库流量控制在一定范围内是治理凌汛灾害的有效途径。然而，这一战略可能会减少水库的社会经济效益，例如减少水电产量。这些相互冲突的目标导致水资源管理者在制定水库调度政策时陷入两难境地。本文以黄河上游7座梯级水库为研究对象，引入防凌库容，以达到发电与防凌的平衡。分析了刘家峡水库防凌蓄水量与梯级发电量的关系。开发了一个优化模型，以探索水力发电和防凌要求之间的权衡。该模型考虑了凌汛控制要求。将优化模型与基于水库调度规则曲线的仿真模型进行了比较。结果表明，优化调度规则能更有效地平衡发电和防凌的效益。本研究所提出的梯级水库调度策略可有效地应用于类似条件下的水库调度系统。(C)2014爱思唯尔有限公司版权所有。
Ice flood control is an important objective for reservoir operation in cold regions. Maintaining the reservoir outflow in a certain range is considered an effective way to remediate ice flood damage. However, this strategy may decrease the socio-economic benefit of reservoirs, for example, reduction of hydropower production. These conflicting objectives cause a dilemma for water managers when defining reservoir operation policy. This study considers seven cascade reservoirs in the upstream Yellow River, and ice flood control storage is introduced to balance the hydropower generation and ice flood control. The relation between the ice flood control storage volume of the Liujiaxia reservoir and cascade power output is analyzed. An optimization model to explore the trade-offs between hydropower generation and ice flood control requirements is developed. The model takes into account ice flood control requirements. The optimization model compared to simulation model based on the reservoir operation rule curves. The results show that the optimal operation rules are far more efficient in balancing the benefits within the power generation and ice flood control. The cascade reservoirs operation strategies proposed in this study can be effectively and suitably used in reservoir operation systems with similar conditions. (C) 2014 Elsevier B.V.
