The Optimal Operation of Parallel Pumping Stations for Inter-Basin Water Transfer Based on the Multi-Objective Optimization of a Single Pumping Station

A nonlinear mathematical model for the optimal operation of a parallel pumping station group was established with objective minimizing costs considering target quantity water extraction and flow unevenness between units each as constraints. The original is decomposed into several sub-models single multi-objective optimization lifting capacity pump coordinating variable. This constructed solved using large-scale system decomposition dynamic programming aggregation method based on sub-system genetic algorithm optimization. Taking Jiangdu in Chinese East Route South-to-North Water Diversion Project case study, results show that under condition 80% load stations 7.8 m daily average lift, unit cost decreases by 4.81%, 19.83% 11.06% compared constant speed at specified angle. 2.16 m3/s, 0.60 m3/s 14.10 m3/s. erosion outlet pool small. article provides theoretical reference same type inter-basin transfer groups.
