Abstract

Hydrogen-powered multi-scale storage systems enhance renewable energy utilization, accelerating the sustainable transition of power systems toward low-carbon operations. To advance this transition, a hydrogen-centric dynamic energy hub model is proposed, integrating producer, prosumer, and consumer hubs with hybrid storage to optimize economic and ecological outcomes under varying weekly weather conditions. The model enhances cost efficiency, environmental sustainability, carbon neutrality, and flexible energy distribution. Demand-side load fluctuations are corrected using a demand response framework, while an optimization approach informed by data-driven, distributionally robust methods mitigates renewable uncertainty with risk-averse dual-norm constrained scenarios. Piecewise linearization, adaptive Big M scenario reduction, and global SCIP solutions in GAMS simplify the complexity of fourth-order polynomial variables. The numerical results demonstrate a significant 4.69% and 18.31% reduction in wind and solar curtailment, 12.336% total model cost savings, and 14.13% emission reductions, ensuring optimal efficiency and sustainability for large-scale deployment in advancing global sustainable urbanization.

具有多尺度混合存储库的氢集成动态多发电枢纽的规避风险分布鲁棒运行协调

氢动力多尺度储能系统提高了可再生能源的利用，加速了电力系统向低碳运行的可持续转型。为了推进这一转变，提出了一个以氢为中心的动态能源中心模型，将生产者、产消者和消费者中心与混合存储相结合，以优化每周不同天气条件下的经济和生态结果。该模型提高了成本效率、环境可持续性、碳中和和灵活的能源分配。需求侧负荷波动使用需求响应框架进行修正，而数据驱动的优化方法，分布式鲁棒性方法减轻了风险规避双规范约束情景下可再生能源的不确定性。GAMS中的分段线性化、自适应大M场景约简和全局SCIP解简化了四阶多项式变量的复杂性。数值结果表明，风能和太阳能弃风量分别减少了4.69%和18.31%，总模型成本节省了12.336%，排放量减少了14.13%，确保了大规模部署的最佳效率和可持续性，以推进全球可持续城市化。
