A method of operating a power plant that includes receiving a measured frequency of a power network to which the power plant is connected, and determining whether the measured frequency falls within a first frequency sub-band that overlaps a network-defined frequency deadband. Based at least in part on the measured frequency, a first control signal is output, indicative of either: a first power offset for application to a baseline frequency curve for the power plant to generate a set point for controlling a power characteristic of the power plant; or a set point for controlling a power characteristic of the power plant, the set point being based on a first power offset applied to a baseline frequency curve for the power plant.
