Abstract
Provided is a method for damping low frequency oscillations, in particular subsynchronous resonances, in an electrical supply grid by way of at least one decentralized production unit connected to the electrical supply grid, in particular a wind turbine or a wind farm, comprising the steps: feeding electrical power by way of the at least one production unit and supplementing the feeding by way of a supplementary component for damping the low frequency oscillations, wherein the supplementary component is determined depending on a simplified model of a synchronous machine.
