Abstract

Water resources in China are unevenly distributed. Although many water transfer projects have been completed, there is a phenomenon of mismatched optimization methods in actual operation, which affects project benefits. Therefore, it is very necessary to conduct a comparative study on the economic operation methods of cascade pumping station groups. This study takes a certain cascade pumping station group as the research object, constructs a dispatch model around the energy consumption optimization objective, and uses MILP, MIQP, POA, and DE to carry out optimization comparisons for two typical scenarios: dry season peak (Condition 1) and rainy season low (Condition 2). The results show that: DE has the fastest solution speed, but the stability of solutions is insufficient due to the influence of random search mechanisms; POA has high solution accuracy and stable results, but its solution efficiency is moderate; MILP and MIQP methods have limitations in accuracy and solution efficiency due to the need for linearization of nonlinear constraints. Moreover, MIQP takes significantly more time than MILP, and in Condition 2, MIQP even exceeds 3600 s without finding a feasible solution. Through quantitative analysis of the performance differences of different solving methods in solving, this study provides a reference for the selection of optimization methods in engineering practice.
