Abstract

An arrangement for generating a control signal for controlling a power output of a power generation system, such as a wind turbine, is provided. The power output is supplied to a utility grid. The arrangement includes a first input terminal for receiving a first input signal indicative of an actual grid frequency of the utility grid, a control circuit for generating the control signal, and an output terminal to which the control signal is supplied. The control circuit includes a bang-bang controller for generating a first power signal being indicative of a predefined amount of power to be added to the power output of the power generation system. The bang-bang controller is adapted to be activated when the first input signal falls below a first predefined threshold. The control signal depends on the first power signal.
