Due to the increasing share of regenerative, decentralized energy generators in the power grid, extreme load scenarios with high power fluctuations and reversed load flows into higher grid levels can occur, which lead to overloading of the lines (bottlenecks) and to violation of the permissible voltage bands. In addition, the volatility of the renewable feed-in makes system balancing more difficult. In order to meet these challenges, the use of flexibility also plays an increasingly important role for decentralised generators. Wind turbines are of particular interest here because, in addition to reducing the output fed into the grid, they also offer the option of short-term overload operation. Allthough, certain operating points are not permitted so that the static stability of the wind turbine is not endangered. Within the scope of this project, flexibility maps are to be determined.
