AI 中文摘要
由绝缘栅双极型晶体管整流器（IGBT-Rs）供电的碱性水电解（AWE）单元，可能因整流器控制与电解槽（ELZ）动态特性的耦合作用而产生振荡。由于该风险随单元负载和功率分配变化，面向生产的调度可能使多电解槽可再生电力制氢（ReP2H）工厂接近或超出其稳定性边界。本文提出一种面向稳定性的控制设计与工厂生产调度框架，采用三端口导纳模型连接交流端口、直流母线和电解槽堆；单元级直流端口分析量化了负载、温度、Buck带宽及直流母线电容的影响，工厂级聚合则评估了单元组合与功率分配对稳定性的作用。结果表明，更高负载会降低稳定性，而更大的直流母线电容和更高的Buck带宽可提升稳定性；在相同工厂负载下，不同功率分配会产生不同的工厂级稳定裕度，平衡分配通常比集中分配提供更大的裕度，该工厂级模型可区分可行调度的稳定裕度。硬件在环（HIL）测试验证了上述趋势及提出的再分配规则，所得的运行区域与调度规则可用于工厂生产调度中筛选单元组合与功率分配决策。
英文摘要
Alkaline water electrolysis (AWE) units supplied by insulated gate bipolar transistor rectifiers (IGBT-Rs) may experience oscil-lations caused by coupling between rectifier control and electro-lyzer (ELZ) dynamics. Because this risk varies with unit loading and power allocation, production-oriented dispatch may place a multi-ELZ renewable power-to-hydrogen (ReP2H) plant near or exceed its stability boundary. This paper proposes a stability-oriented framework for control design and plant production dis-patch. A three-port admittance model links the ac port, dc link, and electrolysis stack. Unit-level dc-port analysis quantifies the effects of loading, temperature, Buck bandwidth, and dc-link capacitance, while plant-level aggregation evaluates how unit commitment and power allocation affect stability. Results show that higher loading reduces stability, whereas larger dc-link ca-pacitance and higher Buck bandwidth improve it. Under the same plant loading, different power allocations result in different plant-level stability margins, with balanced allocation generally providing a larger margin than concentrated allocation. The plant-level model thus distinguishes the stability margins of ad-missible schedules. Hardware-in-the-loop (HIL) tests validate these trends and the proposed redistribution rule. The resulting operating regions and dispatch rules can be used to screen unit commitment and power allocation decisions in plant production scheduling.
