摘　　要：现有的煤电机组灵活性改造方案,聚焦局部与短期,难以消除频繁快速变负荷对热力系统造成的长期寿命折损与安全风险。为提高煤电机组参与电力市场辅助服务的安全性与经济性,提出建立基于氢储能系统的煤电机组系统级灵活性改造方案。分析了现有制氢路线,认为固体氧化物电解槽路线与煤电机组结合度高,且具有辅助煤电机组削减碳排放、提升经营收益的综合优点。以某国产1000 MW超超临界二次再热燃煤机组为应用对象,提出了氢储能系统与煤电机组的可行性结合方案。相关研究成果对于开发新型系统级的安全、健康经济的煤电灵活性提升改造方案具有参考意义。The existing flexible transformation plan for coal fired power units focuses on local and short-term aspects,making it difficult to eliminate the long-term life loss and safety risks caused by frequent and rapid load changes to the thermal system.To improve the safety and economy of coal-fired power units participating in auxiliary services in the electricity market,a system level flexibility transformation plan based on hydrogen energy storage system is proposed for coal-fired power units.After analyzing the existing hydrogen production routes,it is believed that the solid oxide electrolysis cell route has a high degree of integration with coal-fired power generation units,and has the comprehensive advantages of assisting coal-fired power generation units in reducing carbon emissions and improving business profits.A feasible combination scheme of hydrogen energy storage system and coal-fired power unit is proposed based on a domestic 1000 MW ultra supercritical secondary reheat coal-fired unit as the application object.The relevant research results have reference significance for the development of new system level,safe,healthy,and economical coal power flexibility improvement and transformation plans.
