| Abstract_FL | As an important non-engineering measure,the optimal operation of reservoir flood control can reduce the loss caused by flood di-sasters with little investment and plays a key role in flood control and disaster reduction.In this paper,considering the safety of the reservoirs themselves and the safety of the downstream flood control section,a multi-objective optimal model for real-time flood control operation of reservoirs is established with the objective function of minimizing the maximum flow of the downstream flood control section and minimizing the maximum water level of each reservoir.Based on the"filter operator",an improved multi-objective Lichtenberg algorithm(MOLA)is proposed,which is used to solve the multi-objective model,and the real-time flood control operation schemes of the reservoirs are obtained,to enhance the practicability of operation solutions.Finally,a comprehensive screening method based on hierarchical clustering and the phys-ical meaning of Pareto front is proposed to screen the scheduling schemes on the Pareto front and select limited ones for the scheduler,to in-crease the focus of decision-making.Taking the Shiguanhe flood control system of the Huaihe River Basin as an example,this paper applies the multi-objective optimal model for real-time flood control operation of reservoirs.The result shows that the proposed model based on the improved multi-objective Lichtenberg algorithm has high computational efficiency and strong applicability.The gradient analysis method is used to quantitatively analyze the mutual feedback relationship between the maximum water level of Nianyushan Reservoir,the maximum wa-ter level of Meishan Reservoir,and the maximum flow of Jiangjiaji flood control section.The results show that the water level change of Meis-han Reservoir has a more significant impact on the flow of Jiangjiaji section,and the Meishan Reservoir is a priority in flood risk control of Shiguanhe River Basin.The research results can provide decision-making support for real-time flood control operation of reservoirs. |
