effect of wind turbine, solar cells and storages in short term operation of coupled electricity and gas infrastructures in different climates

the biggest challenges faced in big cities are greenhouse gas emission and growing energy needs. efficient utilization of existing infrastructures has a prominent role in response to the challenges. energy hub approach embraces performance of different energy networks. energy hub is defined as a super node in electrical system receiving distinctive energy carriers such as gas and electricity in its input, and based on minimum cost decides when and how much of which energy carrier should supply the hub requirements. in this paper, we examine impact of renewable energy resources (wind and solar) and energy storages (electrical and thermal storages) on short term scheduling of energy hub. effect of the technologies is also investigated on total operation costs of the energy hub in hot and cold climates. mixed integer linear programming (milp) model is used for modeling proposed energy hub. cplex solver of gams software is employed to solve the problem. the results reveal that when and how much of which energy carrier should be exploited to satisfy hub required demands
