Distribution-connected electrolysers with partial loading limit and power response characteristics
- The global power and energy sector is rapidly transitioning toward decarbonization, driven by net-zero targets and long-term sustainability objectives.
- High share of inverter-based resources (IBRs) reduces power system inertia, increasing frequency and voltage stability challenges in modern power systems.
- Hydrogen electrolyzers (HEs) can operate as fast, flexible loads, providing frequency and reactive power support in addition to their hydrogen production.
- Electrolyzer operation is constrained by certain stack constraints such as partial loading limitation imposed for safety and efficiency considerations.
- This work investigates distribution-connected electrolyzers with a single-stage AC–DC converter and evaluates their grid-support capability considering partial load limit and response characteristics.
- A detailed dynamic modeling and control framework is developed and validated through EMT simulation studies, demonstrating frequency and voltage support.
