Methods and systems for operating a wind turbine coupled to a power grid

摘要

According to the present disclosure, a method of operating a wind turbine (10) coupled to a power grid (92) for delivering electric power thereto is provided. The method includes: a) operating the wind turbine (10) in a noise reduction mode; b) determining whether the power grid (92) is in an unstable grid state corresponding to an increase of power demand; and, c) increasing the electric power delivered by the wind turbine (10) to the power grid (92) during a stabilization time period for supporting stabilization of the unstable grid. Further, the increasing of the electric power for supporting stabilization of the unstable grid is performed such that a resulting noise increase is below a selected upper level. In addition thereto, a control system and a wind turbine for performing the above method are provided.
