  "textContent": "The invention relates to a method for operating a thermal power plant (10), which comprises a gas turbine (12) and a generator (13) driven directly by the gas turbine (12) by means of a shaft (14) and being connected to an electrical grid (17) having a grid frequency (F G ) via an electronic decoupling apparatus (15) and a step-up transformer (16). A synthetic inertia response is achieved by said method comprising the steps of: sensing said grid frequency (F G ); detecting if in case of an excursion of said grid frequency (F G ) additional inertial power is required or not; if inertial power is required, calculating the magnitude and duration of the additional inertial power; and releasing additional inertial power to said electrical grid (17) in accordance with said calculations via said electronic decoupling apparatus (15).",
