Abstract: A method for controlling a renewable energy farm (1) comprising a plurality of wind turbines (2) and at least one central control unit (5) is disclosed. The wind turbines (2) of the renewable energy farm (1) are connected to a power grid (3). The central control unit (5) receives a request for change in operation of at least one of the wind turbines (2), where execution of the change in operation causes a change in power output of the wind turbine (2). The central control unit (5) checks whether or not the change in power output is in conflict with at least one obligation of the renewable energy farm (1) towards the power grid (3). In the case that the change in power output is in conflict with at least one obligation of the renewable energy farm (1) towards the power grid (3), execution of the change in operation is deferred.

Abstract: The invention relates to a method for operating a wind turbine. The method comprises monitoring a wind turbine signal for detection of an over voltage of the grid and upon detection of the over voltage, initiate an over-modulation mode wherein the grid side converter is operated with a modulation index being increased in an over-modulation range at least during a sub-period of the over-modulation mode, and upon the detection of the operational condition, initiate a DC-voltage adjustment mode wherein the DC voltage of the DC link is decreased from a second voltage level towards a first voltage level at least during a sub-period of the DC-voltage adjustment mode.
