摘要
This study derives tri-level programming model for multi-reservoir optimal operation in inter-basin transfer-diversion-supply project. Considering the complexity, uncertainty and dynamic nature of the transfer-diversion-supply project, the tri-level programming model is explored in this study to deeply reveal the independency and Inter connectedness of Stackelberg’s decision among transfer, diversion and supply, which is denoted with a set of rule curves of donor reservoirs and recipient reservoirs. Except that the reservoir operation rule can be devised, the model also indicates that it’s possible to establish a greater sustainability. In order to verify the utility of the tri-level programming model, an inter-basin water transfer-diversion-supply project in China is used as a case study. A particle swarm optimization can be easily integrated with simulation models to improve the performance of non-linear optimization. But PSO has premature convergence. IEA has excellent global search performance. So, the IEA-PSO is adopted for optimizing the decision variables. The result shows that the suggested method can achieve operation goal effectively and also improve the operation performance of the inter-basin multi-reservoir system. This article highlights the superior results compared with the current operating control rules.
