Comparison between effect of coupled and independent electricity and gas infrastructures on electric power networks

Gas and electricity infrastructures are independently utilized nowadays. Smart grid technologies enable integration of different energy networks such as gas, heat and electricity energy infrastructures. Combined Heat and Power (CHP) is an important sample of the technologies with significant benefits regarding reliability enhancement, economic improvement, loss reduction, and emission lower. Furthermore, integration of the technologies to electric distribution network prevents huge investment costs from power plant establishment and transmission line expansion in order to supply growing energy demands. In this paper, coupled and dependent electricity and gas infrastructures are optimally operated according to economic, technical and environmental effects on an electric distribution network bus. Energy Hub (EH) concept is used to model the presented approach in this paper. GAMS software is employed to solve the problem. Simulation results compare aforementioned terms by considering utilization of coupled and dependent electricity and gas energy networks.
