  • Method and system for controlling non-inertial generators, in particular wind generators, by inertia emulation
    Patent number: 11441539
    Abstract: A method of controlling, by inertia emulation, electric power generators provided with rotational inertia and connected to the electricity grid with electric power converters includes the steps of measuring grid frequency and/or frequency over-time variation over a rated frequency value; providing a threshold value for, and comparing, the grid frequency or frequency over-time variation; and converting part of the kinetic energy of the generator rotor into electric power to provide additional supporting power to the variation of the grid frequency, wherein the additional supporting power is calculated as a function of the frequency and/or the frequency over-time variation and of a predetermined variable inertia coefficient, the additional power is supplied until the grid frequency variation is restored, and/or the injected power has fallen below a preset limit value, and the coefficient of inertia is calculated by emulating the inertial behavior of synchronous machines, and as a function of rotation velocity.
