    Abstract: A method for starting-up a steam turbine of a combined-cycle power plant is provided. The combined-cycle power plant includes a gas turbine and a steam power generation system having a steam turbine. The combined-cycle power plant activates at least one electric generator connectable to an electric grid. The gas turbine includes a compressor, such that, during starting-up of the steam turbine, both the gas turbine and the steam turbine are in operation. The steam turbine adjusts its load as a function of the load of the gas turbine in such a way that the sum of the load provided by the gas turbine and of the load provided by the steam turbine is equal to the auxiliary power demand of the plant. The load exported to the grid is equal to zero.

    Abstract: The disclosure refers to a method for providing a frequency response for a combined cycle power plant connected to an electric grid. The combined cycle power plant includes a gas turbine engine and a steam turbine engine. The steam turbine engine includes a boiler, a steam turbine, a pump, a condenser, a bypass for the steam turbine, a steam admission control valve. The steam turbine engine operates with the bypass closed or at least partly open to supply steam from the boiler to the condenser bypassing the steam turbine, and/or with the steam admission control valve at least partly open. The method comprises regulating the output load of the combined cycle power plant by regulating the steam admission control valve and/or by regulating the steam flow through the bypass in response to a frequency change of the electric grid. The output of the gas turbine can also be adjusted, such that steam generated by the boiler is sufficient to achieve the target load for the steam turbine.
