并联供水水库群联合调度模型研究

Research on the Joint Operating Model of Parallel Muti-reservoirs

水库群联合调度种类繁多、关系复杂,是水库调度研究的难点与焦点问题。少量的缺水一般不会造成重大损失,但超出用户需求弹性范围会造成重大经济损失。综合考虑研究区域的生活、灌溉、工业、农业等各用水单元,建立了常规水-非常规水、当地水-外调水耦合的水库群联合调度数学模型,通过模拟人机自适应迭代算法进行求解,并以岳城水库、东武仕水库等当地水与南水北调引江水、东风渠引黄水等非当地水源为例,选取25%、50%、75%水平年进行水库群联合调度合理性分析,最终减少了岳城水库、东武仕水库的系统损失,最大化供水满足率。

The joint dispatching of muti-reservoir has many kinds and complicated relationships,which is the difficulty and focus of reservoir dispatching research.A small amount of water shortage generally does not cause significant losses,but exceeding the user's demand elasticity range will cause major economic losses.This paper comprehensively considers the water use units in the study area,such as living,irrigation,industry,agriculture,etc.,and establishes a mathematical model of joint operating of multi-reservoirs for conventional water-unconventional water and local water-external water transfer coupling.The model is solved by simulating the human-machine adaptive iterative algorithm,and the non-local water sources such as Yuecheng Reservoir and Dongwushi Reservoir and the non-local water sources such as the diversion river water from the South-to-North Water Diversion Project and the Yellow River water from the Dongfeng Canal are taken as examples.The rationality analysis of joint operating muti-reservoirs is carried out at 25%,50%and 75%of the annual years.The rationality analysis has finally reduced the system losses of Yuecheng Reservoir and Dongwushi Reservoir and maximized the water supply satisfaction rate.
