With the increasing global demand for clean energy and sustainable development, hydrogen energy has gained significant attention as an environmentally friendly energy carrier. Hydrogen refueling stations, serving as crucial intermediaries in hydrogen production, storage, transport, and refueling, play a pivotal role in the hydrogen energy industry's layout. A novel model for hydrogen refueling stations based on DC microgrids utilizing renewable energy sources for hydrogen production and refueling has become a focal point of interest. However, there is currently limited research on the site selection of electric-hydrogen hybrid refueling stations. Addressing current needs and research gaps, this study proposes a macro-micro two-stage site selection model based on DC microgrids. In the macro-level site selection stage, factors such as regional photovoltaic and wind resources, hydrogen energy policies, and the layout of the hydrogen energy industry are comprehensively considered, with Guangdong Province, China selected as the study area. ArcGIS is utilized to create thematic layers and establish constraints. The DEMATEL method is employed to determine the weights of macro-level site selection criteria. The results indicate that the most suitable areas are located in coastal regions. This study's site selection model offers a scientific and systematic approach to evaluating electric-hydrogen hybrid refueling stations in DC microgrids, providing a scientific basis for decision-making for governments and investors.
