高再エネ比率下で、一定効率モデルでは電解装置の熱慣性・温度変化・起動停止を無視し過度に理想化される問題に対し、PEM電解装置の動特性を考慮した電力-水素連系システムの協調最適スケジューリング法を提案。IEEE30母線系統とベルギー20ノード水素網で検証し、変換効率が温度と入力電力の影響で動的に変動することを示した。一定効率モデルと比べ、新エネ吸収率をわずかに犠牲にしつつ設備寿命と経済性を両立。電解装置容量には便益飽和域があり、合理的な構成が必要と結論。
English
This paper proposes a coordinated optimal scheduling method for electricity-hydrogen coupled systems that captures the dynamic behaviors of PEM electrolyzers (thermal inertia, temperature, start-stop), rather than assuming constant efficiency. Simulations on the IEEE 30-bus system and a Belgium 20-node hydrogen network show conversion efficiency fluctuates with temperature and input power. The model balances equipment lifetime and system economy at a slight cost to renewable accommodation, and identifies a benefit-saturation range for electrolyzer capacity.

📄 Abstract（原文）
<title>Abstract</title> <p>In scenarios with high-penetration renewable energy, conventional scheduling for electricity-hydrogen coupled systems mostly adopts a constant-efficiency electrolyzer model, which neglects thermal inertia, temperature variations and start-stop behaviors, leading to overly idealized optimization results. To address this issue, this paper proposes a coordinated optimal scheduling method for electricity-hydrogen coupled systems considering the dynamic behaviors of PEM electrolyzers. An energy-conversion model of the electrolyzer that captures its dynamic behaviors is established and coupled with the power system. A coordinated scheduling model is formulated with the objective of minimizing the comprehensive operating cost. Simulations are carried out based on the IEEE 30-bus power system and the Belgium 20-node hydrogen energy system. The results demonstrate that the conversion efficiency of the electrolyzer fluctuates dynamically under the combined effect of temperature and input power. Compared with the constant-efficiency model, the proposed model balances equipment safety-service life and system economy at the cost of a slight reduction in new-energy accommodation rate. There exists a benefit-saturation range for electrolyzer installed capacity, which requires rational configuration according to source-grid-load conditions. This research can provide references for practical scheduling of electricity-hydrogen coupled systems.</p>
