A METHOD FOR CONTROLLING A POWER PLANT

Abstract: a method for controlling a power plant comprising one or more wind turbine generators and one or more power-to-x units, the power-to-x unit being configured to convert electric power from the power plant to x, the power plant being connected to an electric power grid. the method comprises: in response to an under-frequency support request with regard to the electric power grid, determining to initiate an inertia emulation response period of the one or more wind turbine generators so as to increase the electric power generation of the wind turbine generator for providing frequency support to the electric power grid; and when or after it has been determined to initiate the inertia emulation response period, initiating an electric power consumption reduction period of the power-to-x unit so as to reduce the electric power consumption of the power-to-x unit to a lower level or zero.
