Resilience-Assuring Hydrogen-Powered Microgrids

Green hydrogen has shown great potential to power microgrids as a primary source, yet the operation methodology under extreme events is still an open area. To fill this gap, this letter establishes an operational optimization strategy towards resilient hydrogen-powered microgrids, where the frequency and voltage regulation characteristics of hydrogen sources under advanced controls are accurately represented by piecewise linear constraints. The results show that the new operation approach can output a safety-assured operation plan with rational power change distribution and reduced frequency and voltage variation.
