针对双库库群联合供水调度问题,提出了一种基于二维水库调度图的水库群联合供水优化调度方法.二维水库调度图在由表示双库系统中各水库蓄水量的2条坐标轴与时间轴构成的三维坐标系下充分考虑每个水库蓄水量,在此基础上确定水库群的联合供水决策,并采用粒子群优化算法对调度图关键控制点位置进行优化.碧流河、英那河水库群的调度实验表明:二维水库调度图与基于聚合水库的一维调度图的调度结果相近,明显优于独立调度的结果.
An operation pattern based on two-dimensional scheduling charts was proposed to resolve the problems of jointly scheduling water-supply dual-reservoir system.For a single reservoir operation,only one coordinate axis was used to describe the reservoir storage.Differently,the proposed operation pattern employs two coordinate axes to represent the reservoir storages of water-supply dual-reservoir systems,respectively.The water releases from the dual-reservoir system for the common water demand can be determined according to the two-dimensional scheduling chart.The dual-reservoir system of Biliu River and Yingna River was employed as a case study to analyze the performance of the two-dimensional scheduling chart.The results indicate that the benefits from the two-dimensional scheduling chart are close to those of equivalent-reservoir-based one-dimension operating chart,and have a significant improvement,compared to those of the independent operation pattern.
