Multi-Objective Flood Control Scheduling Study of the Suyukou Ditch Considering Flood Control Safety of the Downstream River

Abstract

As an important flood control project, a flood control reservoir is charged with the dual tasks of flood control safety and rainwater utilization. This paper establishes a multi-constrained optimal flood control scheduling model based on a differential evolutionary algorithm with the objective of the lowest maximum water level in front of the dam and minimum maximum discharge flow and gives the steps of solving the DE algorithm for optimal flood control scheduling of the interceptor reservoir. The algorithm is applied to solve the flood control optimization scheduling example problem of the Jinshan flood control reservoir, and the solution result is compared with the conventional scheduling situation. The result shows that the algorithm can generate a scheduling solution in a short time and provide a reference for the multi-objective flood control scheduling decision of the flood control reservoir.
