大规模跨流域水库群供水优化调度规则

针对大规模跨流域供水水库群联合调度中调水、引水、供水三者之间的复杂性、动态性和不确定性的特点,在二层规划模型的基础上,应用博弈论原理,建立跨流域水库群供水调度规则的三层规划模型,提出调水规则、引水规则和供水规则相结合的跨流域水库群优化调度规则,从深层次揭示跨流域供水水库群之间的主从递阶层次的独立性及相互关联性;并应用基于免疫进化的粒子群算法对模型进行分层优化求解。以滦河下游跨流域水库群为对象进行研究,计算结果表明:① 减少了水量损失,提高了水资源的利用率;② 提高了供水区唐山、天津的供水保证率,降低了缺水破坏深度。

Scheduling rules of multi-reservoir optimal operation in large-scale inter-basin water supply reservoirs

Aiming at the characteristics of complexity, dynamism and uncertainty among water transfer, water diversion and water supply in joint regulation of large-scale inter-basin water supply reservoir group, on the basis of bi-level programming model, applying game theory, tri-level programming model of inter-basin reservoir group water supply operation rules is built up and inter-basin reservoir group optimization operation rules after combining water transfer, water diversion and water supply is carried out, revealing the independence and interconnection of principal and subordinate hierarchy among inter-basin reservoir group in deep level; and applying particle swarm optimization based on immune evolutionary to have hierarchical optimization solution for model. Taking the lower reaches of the Luanhe River inter-basin reservoir group as research object, the calculation results show: ① reduce water loss and increase the utilization ratio of water resource; ② increase the guaranteed rate of water supply in Tangshan and Tianjin as well as lower lack of water damage depth.
