    Hybrid genetic algorithm for parametric optimization of surface pipeline networks in underground natural gas storage harmonized injection and production conditions by Jun Zhou, Zichen Li, Shitao Liu, Chengyu Li, Yunxiang Zhao, Zonghang Zhou, Guangchuan Liang

    Published 2025-04-01
    “…The HGA-GRG demonstrated significant advantages in optimization outcomes, reducing the initial cost by 345.371 × 104 CNY compared to the GA, validating the effectiveness of the model. By adjusting algorithm parameters, the optimal iterative results of the HGA-GRG were obtained, providing new research insights for the optimal design of a SIPS.…”
