再生可能エネルギー比率100%の島嶼マイクログリッドにおいて、PEM電解槽をグリッドフォーミング資産として活用し、仮想同期機制御により周波数安定性を向上させる手法を提案。シミュレーションでは、専用BESSと同等以上の周波数変化率低減効果（68%削減）を達成しつつ、水素生成量の減少は0.4%未満に抑えられることを示した。
English
This paper proposes using PEM electrolyzers in green hydrogen facilities as grid-forming assets with virtual synchronous machine control to provide synthetic inertia in 100% renewable islanded microgrids. Simulations show a 68% reduction in rate of change of frequency during a severe contingency, matching or exceeding dedicated BESS, while reducing hydrogen yield by less than 0.4%.

📄 Abstract（原文）
As power grids transition toward fully renewable, inverter-based generation, the loss of mechanical rotational inertia threatens frequency stability, and dedicated battery energy storage systems (BESS) traditionally deployed to supply synthetic inertia add substantial capital cost to microgrid projects. We propose instead using megawatt-scale proton exchange membrane (PEM) electrolyzers within green hydrogen facilities as grid-forming assets, and formulate a virtual synchronous machine (VSM) control topology for the electrolyzer's power electronics that modulates its multi-megawatt power draw within milliseconds. Time-domain simulation of a 100% renewable islanded microgrid shows that grid-forming electrolyzer control reduces the rate of change of frequency by 68% during a severe contingency, matching or exceeding a dedicated BESS while reducing daily hydrogen yield by less than 0.4%.
