发布时间：2019-02-27 08:33
【摘要】：针对人工鱼群算法全局搜索和局部搜索平衡能力较弱、算法运行后期搜索盲目性加大等问题,提出了人工鱼视野和步长的动态自适应调整、年际间缺水率均衡的动态控制等改进措施,建立了求解多年调节水库旱限水位的改进人工鱼群算法。通过黄河连续枯水段1990—1999年的实例研究,应用基于改进人工鱼群算法优化龙羊峡水库旱限水位,并与实际调度进行了对比。结果表明:优化控制可以合理预留调度期末水库蓄水量,流域缺水率均控制在10%左右,实现了年际间缺水均衡。
[Abstract]:Aiming at the weak balance between global search and local search of artificial fish swarm algorithm, and the increasing blindness of search in the late stage of the operation of the algorithm, a dynamic adaptive adjustment of artificial fish field of view and step size is put forward. In this paper, an improved artificial fish swarm algorithm is established to solve the problem of multi-year regulation of the water level in the reservoir by the dynamic control of the inter-annual water deficit equilibrium. Based on the case study of the continuous low water section of the Yellow River in 1990 / 1999, the optimization of the limited water level of Longyangxia Reservoir based on the improved artificial fish swarm algorithm is carried out and compared with the actual operation. The results show that the optimal control can reasonably reserve the reservoir water storage at the end of the operation period, and the water deficit rate of the basin is controlled at about 10%, which realizes the inter-annual balance of water shortage.
