  7. Abstract:
  8. The production of green hydrogen from renewable technologies, and the use of hydrogen vehicles (HVs) in an energy hub (EH) can greatly help to reduce environmental pollution and have a sustainable energy system. This paper presents a model in which unit commitment (UC) can reduce the costs of an energy hub by optimizing the utilization of hydrogen vehicles and implementing demand response (DR). In this study, a stochastic model for unit commitment in energy hubs is designed, which includes hydrogen vehicle (HV), electric heat pump (EHP), absorption chiller (AC), boiler, hydrogen electrolysis (HE), fuel cell (FC), electric storage (ESS), hydrogen storage (HSS), thermal storage (TSS) and cooling storage (CSS). Grid electricity and gas, along with the photovoltaic system, are the input of the energy hub to meet the demands of heating, cooling, electricity, hydrogen and NG. On the other hand, uncertainties of hydrogen vehicles and PV power are modeled and the impact of green hydrogen, storage systems, hydrogen vehicles and demand response (DR) on EH performance is investigated. First, the operating model of vehicles is solved in python and then by linking to the main model, it is solved as a MILP with the CPLEX solver in GAMS software. The results show that uncertainty in hydrogen vehicle demand and considering demand response reduce costs by 2.5% and 17%, respectively. Uncertainty along with demand response can reduce the final hub cost by 22% and the use of vehicles operation plan improves hub performance by 4% compared to the normal operating mode
