Abstract
Integration of electricity and gas networks offer extra flexibility to system operation and improves energy efficiency. The energy hub (EH) plays an important role in energy production, conversion, and storage in such a coupled infrastructure. This paper proposes a new approach for the operation of EH considering renewable energy sources (RESs) and battery energy storages system (BESS). The objective of the proposed model is to optimize total energy costs based on hourly demand of electricity and heat considering the hub constraints. Also, the effects of energy price, load demands, RESs and BESS on the performance of the EH model has been investigated. The optimization problem has been examined in three operational case studies based on different EH structures. A Mixed integer linear programming (MILP) formulation for the optimization problem is presented and solved using the CPLEX solver in general algebraic modelling system (GAMS) software. The simulation results show a reduction in the cost of purchased energy from the market
