AI 中文摘要
电力与氢能部门日益紧密的互动凸显了电解槽与电动压缩机组（EDCS）协调运行的重要性，在瞬态扰动下这一重要性尤为突出。然而，这些耦合子系统的协调动态交互仍在很大程度上未被探索。本文通过开发集成电解槽-EDCS系统的动态模型并设计合适的PID控制方案，以应对影响任一组件的潜在扰动，填补了这一空白。为此，首先推导电解槽和EDCS的线性化模型，以实现系统化的控制器设计；随后开发代表保守型和快速跟踪型设计的两个PID控制器，用于协调系统响应。所开发的协调模型在四种不同工况下接受检验与验证。结果表明，所提出的模型在压缩机驱动器或电解槽的扰动下均有效：针对EDCS扰动控制电解槽流量可协调系统动态并抑制有害瞬态波动；反之，在电解槽扰动下调节EDCS转矩可消除压力、流量和转速的不一致响应，同时避免危险的瞬态 undershoot 和 overshoot。总体而言，所提出的框架保障了集成电解槽-EDCS系统的瞬态稳定性与运行可靠性。
英文摘要
The increasing interaction between power and hydrogen sectors highlights the importance of coordinated operation of electrolyzers and electric-driven compressor stations (EDCSs). This becomes particularly of higher importance under transient disturbances. However, coordinated dynamic interactions of these coupled subsystems remain largely unexplored. This article addresses such gap by developing a dynamic model for an integrated electrolyzer-EDCS system and designing appropriate PID control schemes to address the potential disturbances affecting either component. To this end, linearized models of the electrolyzer and EDCS are first derived to enable systematic controller design. Then, two PID controllers, representing conservative and fast-tracking designs, are developed to coordinate the system response. The developed coordinated model is examined and verified under four different cases. The results demonstrate the effectiveness of the proposed model under disturbances from the compressor driver or the electrolyzer. Controlling the electrolyzer flow in response to EDCS disturbances coordinates system dynamics and mitigates undesirable transient fluctuations. Conversely, under electrolyzer disturbances, regulating the EDCS torque eliminates inconsistent responses in pressure, flow, and rotational speed, while preventing hazardous transient undershoots and overshoots. Overall, the proposed framework guarantees transient stability and operational reliability of the integrated electrolyzer-EDCS system.
