Abstract

Green-hydrogen plants, connected to weak power grids in geographically remote areas, are prone to frequency fluctuations and instability due to the variability in renewable-energy generation. Disclosed embodiments provide balancing control within the green-hydrogen plant to provide both fast frequency response during contingency conditions and automatic frequency regulation during normal conditions. The fast frequency response may be centralized or distributed, and may combine frequency droop response with fast frequency response or synthetic inertial response. The automatic frequency regulation may determine optimal allocations of a total net power adjustment, which compensates a balance control error in the system, to a plurality of different power resources of the green-hydrogen plant. These power resources may comprise electrolyzer plant(s), renewable energy source(s), and/or energy storage system(s).
