Abstract
The invention relates to a method for controlling a power plant during an event which requires a change of the power produced by the power plant, wherein the power plant comprises a plurality of power generating units including at least one wind turbine generator, the method comprises determining the power reference dependent on an available power, changing the power reference to a modified power reference by a power variation in response to detecting a first event, memorizing a power level relating to the actual power production at a time occurrence of the first event, setting a maximum power limit to the memorized power level, limiting the modified power reference to the maximum power limit, and controlling the power produced by the wind turbines in accordance with the limited modified power reference.
