摘要：
在孤岛微电网中利用风力发电为电解槽供电是绿氢生产的重要技术路径，在向净零碳排放转型的过程中日益受到关注。学术界和工业界普遍认为，孤岛型交流微电网通常依赖电池储能系统（BESSs）实现构网功能。然而，BESS的高成本显著推高了平准化氢成本（LCOH），削弱了经济可行性。为应对这一挑战并降低LCOH，本文聚焦于无储能微电网中向电解槽供电的风力涡轮机（WT），并发现了一个挑战对该微电网传统认知的独特特性：有功功率与微电网电压而非频率耦合，频率则与有功功率平衡完全解耦。基于这一独特特性，本文提出了一种新型控制策略，可维持功率平衡、稳定电压和频率，并最大化产氢量。通过在Matlab/Simulink中开展的案例研究验证了该控制策略的有效性，尤其验证了其在多种工况下既能维持稳定性又能最大化产氢量的能力。
英文摘要：
Wind power generation supplying electrolyzers in islanded microgrids is an essential technical pathway for green hydrogen production, attracting growing attention in the transition towards net zero carbon emissions. Both academia and industry widely recognize that islanded AC microgrids normally rely on battery energy storage systems (BESSs) for grid-forming functions. However, the high cost of BESS significantly increases the levelized cost of hydrogen (LCOH), compromising economic feasibility. To address this challenge and reduce the LCOH, this paper focuses on a wind turbine (WT) supplying an electrolyzer in a storage-less microgrid and identifies a unique characteristic that challenges the conventional understanding of this microgrid: active power is coupled with microgrid voltage rather than frequency, the latter being entirely decoupled from active power balance. Based on this unique characteristic, this paper develops a new control strategy that maintains power balance, stabilizes the voltage and frequency, and maximizes hydrogen production. The effectiveness of the control strategy is validated through case studies conducted in Matlab/Simulink, especially its capability to maintain stability while maximizing hydrogen production under various conditions.
