基于动态权重系数的串联水库供水规则研究

Study on the water supply rules of cascade reservoirs based on dynamic weight coefficient

本文针对串联水库群联合优化调度问题展开研究,通过在单库调度图上添加补偿供水调度线的方式将各成员水库联系起来,采用动态分水权重系数计算得到上游水库补偿下游水库水量。以观音阁、葠窝水库为例,采用粒子群算法对联合调度模型决策变量进行优化,得到满足不同用水户保证率及破坏深度要求的水库供水调度规则,为水库的调度运行提供参考。

Cascade reservoirs group joint optimization scheduling problem is studied in the paper. All member reservoirs are linked through adding and compensating water supply scheduling lines on the single reservoir scheduling map,dynamic water diversion weight coefficient method is adopted to obtain the water quantity compensated by upstream reservoir to downstream reservoir. Guanyinge Reservoir and Shenwo Reservoir are adopted as an example. Particle swarm algorithm is adopted to optimize the joint scheduling model decision variables. Reservoir water supply scheduling rules satisfying different water user reliability rates and failure depth requirements are obtained,thereby providing reference for reservoir scheduling operation.
