Impacts of gas network emergencies on power system through gas turbine

The rapid development of Energy Internet has enhanced the interdependency between gas networks and power systems. As the medium to convert natural gas into electricity, gas turbine is playing a more and more important role in the optimal scheduling problem. The output of gas network has a non-ignorable impact on the output of gas turbine. This paper tries to establish a model of gas turbine to study the output characteristics of it. The gas flow will influence the rotating speed and active power of gas turbine. When there are some emergencies in gas network and gas flow is changed, the performance of gas turbine will affect the steady of power system. This paper uses a rapid decrease of gas supply to simulate this situation and discusses its influence.
