Optimal Management of Energy Hub with Considering Hydrogen Network

Nowadays, energy networks including electricity, natural gas and heat are integrated in a unit namely “Energy Hub The energy hub has led a great opportunity for energy system operators to achieve a system with higher efficiency as well as better performance. In this paper, optimal energy management of an energy hub is proposed to simultaneously minimize the operation costs and emissions (inside and outside the hub) in the presence of wind turbine and demand response. Also, in the proposed energy hub, combination of fuel cell and electrolyzer and hydrogen storage tank is used as a hydrogen storage system to store extra hydrogen or electricity. The problem is solved as a two-objective MILP optimization problem in GAMS. The simulation results obtained by the proposed model show the appropriate effect of the model on an optimal management of energy hub in a daily operation.
