When conventional power plants are shut down, the inertia of the synchronous generators stabilizing the power grid is lost. Wind turbines could step in here. However, can they withstand the resulting mechanical loads? The “GridLoads” research project, successfully completed by Fraunhofer IEE and MesH Engineering GmbH, now clearly shows that the plants can basically cope well with this—provided that the control modules of the plants are equipped for the new task beforehand. To analyze the occurring electromechanical oscillation modes, the researchers have carried out complex simulations.
