针对电氢系统运行经济性提升需求，提出了一种计及分时电价的含退役动力电池分级控制的电氢系统容量优化配置方法。该方法分析了退役动力电池的余能衰退率，提出了延长退役电池使用寿命的退役动力电池分级控制策略，在此基础上，设计了优先满足电负荷、电解槽由退役动力电池供能的电氢系统运行控制策略，构建了融合分时电价机制的电氢系统容量优化配置模型。算例结果表明，在考虑分时电价和分级控制策略的情况下，运行成本约为23.98万元，比含新电池的分级控制策略和含退役动力电池的整体控制策略均有良好的经济性和适用性，而且退役动力电池的衰退率为整体控制策略下的52%左右。

To address the demand for improving operational economy in electric hydrogen systems, a capacity optimization configuration method of electric hydrogen systems is proposed with hierarchical control of decommissioned power batteries considering time-sharing tariff. The remaining energy decay rate of decommissioned power batteries is analyzed and a hierarchical control strategy is presented to extend their service lives. On this basis, an operational control strategy is designed that prioritizes electric load satisfaction and powers the electrolyzer using decommissioned batteries. A capacity optimization configuration model of the electric hydrogen system incorporating the time-sharing tariff mechanism is established. Case study results demonstrate that under consideration of time-sharing tariff and hierarchical control strategies, the operational cost reaches approximately \mathrm{\yen } 239 800. This configuration exhibits superior economic performance and applicability compared to both hierarchical control strategies with new batteries and integrated control strategies with decommissioned batteries. Moreover, the decay rate of decommissioned batteries under this strategy measures about 52% of that observed in integrated control strategies.
