Hydrogen energy is an important carrier for China's low-carbon transformation, with zero emissions and renewable characteristics. The carbon emissions and economic benefits of hydrogen storage optimization configuration are poor in existing park integrated energy systems based on photovoltaic hydrogen production. Therefore, a hydrogen storage optimization configuration method for park integrated energy systems is proposed, which takes into account photovoltaic photothermal proton exchange membrane electrolysis for hydrogen production (PV/T-PEMWE) and stepped carbon trading. Firstly, considering the comprehensive energy supply characteristics of the park, an integrated energy system framework containing PV/T-PEMWE is constructed for the park. Secondly, the working principles of photovoltaic photothermal technology (PV/T) and proton exchange membrane electrolysis for hydrogen production (PEMWE) are analyzed and PV/T and PEMWE are coupled. And a PV/T-PEMWE model is established. Finally, by introducing a stepped carbon trading mechanism and aiming at the economic and low-carbon aspects of the system, a hydrogen storage optimization configuration model for the integrated energy system in the park is constructed. Taking a integrated energy system in a certain park in the northwest region as an example for simulation, the advantages of the proposed model in terms of economy and low-carbon are verified.
