Offshore wind farms with zero-cent subsidy bids and post-EEG wind turbines must generate their income solely from the electricity market. This requires forward-looking operating strategies that take into account not only market prices but also the expected wear and tear on the turbines the next day. The Fraunhofer IEE is now working with the companies MesH Engineering and anemos Gesellschaft für Umweltmeteorologie on the BMWK-funded OTELLO project to develop new tools that can be used to optimize schedules for wind farms. Among other things, the experts are integrating short-term forecasts of turbulence intensity - the key factor for turbine wear and tear.
