Abstract
Embodiments of the disclosure provide a method for controlling a power plant. The method may include detecting a transient load on the power plant, and monitoring a system reactance during operation at the transient load. A system reactance of the grid is compared with a switching threshold indicative of a switching event on the set of transmission lines. If the switching threshold is exceeded, the gas turbine operates at the transient load using a first control setting with a transient fuel management profile, a transient split bias profile, and a dynamic intake parameter for the gas turbine. If the switching threshold is not exceeded but one of the electrical properties exceeds a stability threshold, the gas turbine operates at the transient load using a second control setting with the dynamic intake parameter for the gas turbine, and without the transient fuel management profile or the transient split bias profile.
