Evaluating the Impact of Fuel Switching Units and Power to Gas Technology in Co-Optimization of Electricity and Natural Gas Networks

Growth the number of gas-fired units in power system has increased the interactions between electricity and natural gas networks. On the other hand, the power to gas technology has intensified these interactions by converting surplus wind power into natural gas. This paper proposes a co-optimization model of integrated electricity and natural gas system considering power to gas technology. As well as, fuel switching unit considered as an effective option to improve security and economical operation of two systems. The proposed model is performed on a six bus power system with a six node natural gas network. The benefits of using power to gas technology and fuel switching units in electricity and natural gas network operation are demonstrated as the results of simulations.
