Abstract: The siting and sizing for the hydrogen producing and refueling station（HPRS） and wind farms in the wind-hydrogen-electricity coupled network are studied with the intent of realizing the scientific layout of HPRS and wind farms. Firstly, a full-process model for HPRS including hydrogen production, compression, storage and injection into hydrogen fuel vehicles is proposed to simulate the hydrogen production and consumption of HPRS with on-site water electrolysis. Secondly, the hydrogen refueling logic rules and network expansion technique in the traffic network are introduced. Finally, a wind-hydrogen-electricity coupled network planning model considering traffic flow capture is developed by simultaneously taking into account the traffic network constraints, power network constraints and equipment operation constraints. Taking the IEEE 33-bus electricity network and 25-bus traffic network as case systems, the research results verify the effectiveness of the proposed model.
