Optimal Economic Dispatch of Hydrogen-Electricity Coupled Multi-Microgrid Considering Hydrogen Tube Trailers' Transportation

With the rapid advancement of hydrogen technology and its expanding application in microgrids, the research on hydrogen and electricity interactions has become a critical area in the energy sector. In this paper, a hydrogen-electricity coupled multi-micro grid (MMG) energy interaction framework is established, which transfers hydrogen and electricity through hydrogen tube trailers and power lines. Then, an optimal economic dispatch model of the MMG is proposed. This model aims to minimize the operating cost of the MMG, considering the constraints of equipment, hydrogen tube trailers, and hydrogen-electricity balance. Finally, through case studies, the proposed optimal economic dispatch has been proven to reduce the operation cost of the MMG effectively, with a reduction of 3.6%.
