On the grid power, the generation power should be used immediately to maintain the grid frequency constant. Therefore, grid generation power at any moment must be equal to the grid consumption power. Increasing or decreasing grid consumption power leads to the request for an increase or decrease in grid generation power; and if this request is not provided by the units in the grid generation power, a power difference will be created causing the grid frequency deviation from its nominal value. This grid power control process is called frequency control. In Iran, the main component of frequency control is provided by gas turbines. As gas turbines have been more installed in the country, the response of gas turbines to grid frequency variations has become more and more important. In order to study the frequency response of these systems, an appropriate gas turbine model is required. In this paper, the frequency model of a gas turbine has been identified. After modeling, the model's response against the errors applied to the gas turbine from the grid power is investigated by MATLAB software.
