【摘要】：为了有效描述和求解跨流域水库群最优调供水过程,本文建立了基于0-1规划方法的水库群最优化调度模型,统一考虑并最终确定了最优调供水过程。为减少模型单次求解的变量数目,同时增加算法全局搜索的能力,本文借用逐步优化算法思想,对传统粒子群进行改进,提出了逐步优化粒子群算法(PRA-PSO)对模型进行求解。最后,通过中国北方某大型跨流域调水工程的实例研究分析了模型的合理性和有效性。最优调供水过程的确定不仅可为采用隐随机优化方法确定跨流域水库群调水规则和供水规则提供最优化样本过程,而且对跨流域调水工程调度运行评价具有重要意义。
[Abstract]:In order to effectively describe and solve the optimal regulation and water supply process of cross-basin reservoir group, this paper establishes the optimal operation model of reservoir group based on 0-1 programming method, and considers and finally determines the optimal water supply process. In order to reduce the number of variables solved by single time and increase the ability of global search, this paper uses the idea of stepwise optimization algorithm to improve the traditional particle swarm optimization (PSO), and proposes a stepwise optimization PSO (PRA-PSO) algorithm to solve the model. Finally, the rationality and validity of the model are analyzed by an example of a large water transfer project in the north of China. The determination of optimal water supply process can not only provide the optimal sample process for determining the water transfer rules and water supply rules of cross-basin reservoir groups by using implicit stochastic optimization method, but also play an important role in the operation evaluation of cross-basin water transfer projects.
