With the expansion of natural gas pipelines into larger networks; there is a growing concern regarding energy consumption in the operations of pipeline systems. However; the intricate network structure and hydraulic properties pose challenges for operation optimization. In this paper; a Mixed Integer Nonlinear Programming model is proposed to optimize the steady-state operation of natural gas pipeline network; aiming to minimize the energy consumption of compressor units. The model incorporates constraints related to flow direction; flow balance; pressure drop in pipeline sections; and pressure increase at compressor stations. To solve the complex nonlinear model efficiently; a stochastic optimization algorithm that integrates particle swarm optimization and high-fidelity simulation is proposed. The case study is conducted on a large-scale natural gas pipeline network consisting of forty-three pipeline sections and four compressor stations. The optimal operation scheme is calculated; and the outlet pressures of each compressor are determined. The results demonstrate that the stochastic optimization algorithm proposed in this paper can reduce energy consumption by 21.23 % at most and 19.77 % on average during pipeline operation; which can provide guidance for the operation management of large-scale natural gas pipeline network. © 2024;
