跨流域水库群最优调供水过程耦合研究

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的思想，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。

The study on coupling of optimal water transfer and supply process for inter-basin water-transfer multi-reservoir system

For delineating and solving water transfer and supply processes of inter-basin water-transfer multi-reservoir system, the 0-1 programming method is employed in this study to determine the optimal water-supply and water-transfer progress, which need to be considered together in the joint operation process. For reducing decision variables in single optimization and improving the global search ability, the principle of Progressive Optimization Algorithm is adopted to develop the traditional Particle Swarm Optimization algorithm into a Progressive Reservoir Algorithm - Particle Swarm Optimization (PRA-PSO) to solve the optimization model. Finally, an inter-basin water transfer project in North China is taken as the case study to verify the reasonability and efficacy of the model. The optimal operation process not only can provide the data samples for stochastic optimization operation, but also can be used to evaluate the operation result of multi-reservoir system.
