Abstract

Research on offshore wind power-based hydrogen production technology provides an effective way for meeting the energy supply-demand of remote island users and promoting the realization of the goals of “carbon peaking and carbon neutrality.” Therefore, a fuzzy robust optimal operation strategy for an island park multi-microgrid system considering offshore wind power-based hydrogen production and green hydrogen trading was proposed. Firstly, the operation mechanism of offshore wind power-based hydrogen production was explored, and an offshore wind power-based hydrogen production system integrating seawater desalination, offshore wind power-based hydrogen production, hydrogen compression, and hydrogen transportation was constructed. Secondly, to improve green hydrogen consumption, green hydrogen certificates were introduced, and a green hydrogen certificate trading mechanism was proposed to promote the coordinated operation of green hydrogen and green electricity. Finally, considering the multiple uncertainties of sources and loads in the system, the uncertainties of sources and loads in the multi-microgrid were modeled based on fuzzy theory and robust theory. A fuzzy robust low-carbon economic scheduling model for the island park multi-microgrid system was constructed, and the model was efficiently solved based on the equivalent deterministic transformation idea and adaptive harmonic aliasing composite differential algorithm. The case study results show that the proposed model can effectively promote the consumption of offshore wind power and green hydrogen, and take into account system robustness, low-carbon performance, and economy.
