Abstract

Abstract: The desire of achieving carbon neutrality and the decarbonization objective is the key driver for the interest in green hydrogen for power plant generation as a clean and flexible energy carrier. In fact, the use of hydrogen-based generating plants as hydrogen fuel cells in solar microgrids plays a major role in the energy transition and adds more reliability to this type of microgrid. This study presents a hierarchical control level 1 and 2 of an islanded microgrid with green hydrogen production, storage, and re-electrification. The purpose of this article is to control a stand-alone/off-grid microgrid with renewable hydrogen storage-based non-dispatchable sustainable energy solutions. An energy management strategy was implemented and a primary and secondary control was applied in order to maintain the voltage and frequency of the islanded microgrid at their steady state values. Highlights: Power-to-X: green hydrogen conversion unit. Low-voltage solar microgrid with hydrogen production, storage, and re-electrification. Direct droop control, of a renewable hydrogen-powered islanded microgrid under load step-change condition.
