An optimization method for head assignment of cascade pumping stations based on grey wolf algorithm

Abstract

The invention discloses an optimization method for head distribution of a cascade pump station based on a grey wolf algorithm, which relates to the field of water conservancy system optimization. Through the adoption of large-scale system decomposition Coordination model, the optimal head distribution system of cascade pumping station is divided into two subsystems, and the GWO algorithm is used to solve the system model for the two subsystems respectively, the flow rate and head distribution of each pumping station are calculated by the second-layer subsystem, and substituted as an initial value into the first tier subsystem, the optimal head distribution of the cascade pumping station is obtained by returning the optimal value of the second-layer subsystem to the second-layer subsystem,which improves the precision of the optimal calculation and the efficiency of the cascade pumping station. The optimal head distribution of the cascade pumping station is obtained by calculating the optimal value of the second-layer subsystem. In addition, the invention considers the canal conveyance loss and serves the calculated head loss to the optimal head allocation of the cascade pumping station, thereby realizing the overall simulation of the optimal head allocation process.

Description

technical field [0001] The invention relates to the field of water conservancy system optimization, in particular to an optimization method for head distribution of cascade pumping stations based on gray wolf algorithm. Background technique [0002] With the development of the national economy, the shortage and unreasonable distribution of water resources are becoming more and more serious. In recent years, in order to promote the optimal allocation of water resources, many large and medium-sized cross-basin water diversion projects and general water supply projects have been built in China. Such as the first phase project of the eastern route of the South-to-North Water Diversion Project, the Dongshen Water Supply Project, and the Wanjiazhai Yellow River Diversion Project in Shanxi, etc. In these projects, cascade pumping stations often play a huge role. Cascade pumping stations can realize water transfer within or between river basins, and can effectively solve the probl...
