Optimal Scheduling of Reservoir Flood Control Based on Multi-Objective Cluster Decomposition

中文摘要英文摘要

针对水库防洪多目标优化中决策空间受限的难题,研究提出融合改进型NSGA-Ⅱ算法与多目标聚类分解的协同决策框架,通过对帕累托前沿解的聚类分解提供不同决策偏好的最优调度决策.将所提方法在 A水库进行应用,得到以下结论:① 多目标优化可显著提高 A水库防洪效果,防洪优化调度的帕累托前沿解最多可使下游洪峰流量、高流量历时以及调洪高水位分别降低33.4%、12.7%以及1.32 m.② 综合考虑多目标防洪优化时,多目标聚类分解可提供更具针对性的决策导向方案:优先保障水库防洪安全时,调洪高水位可降低1.5 m;优先保障下游防洪安全时,下游洪峰流量可降低25.3%.

To address the problem of decision-making space constraints in multi-objective optimization for reservoir flood control,this study proposes a collaborative decision-making framework that fuses an improved NSGA-Ⅱ algorithm with multi-objective cluster decomposition.The Pareto frontier solution is clustered and decomposed to provide optimal scheduling decisions with different decision preferences.The application of the proposed method to A Reservoir yielded the following conclusions:①Multi-objective optimization can significantly improve the flood control effect of A Reservoir.The Pareto frontier solution of flood control optimization scheduling can reduce the downstream peak flood flow,the duration of high flows,and the flood high water level by 33.4%,12.7%,and 1.32 m,respectively.② Considering competition among multiple objectives,multi-objective clustering decomposition offers more targeted decision-making guidance:prioritizing reservoir flood control safety cuts the flood regulation high water level by 1.5 m;prioritizing downstream flood control safety reduces downstream flood peak discharge by 25.3%.
