Abstract: The present invention relates to a method of operating a wind power plant, with at least one wind turbine generator connected to an electrical grid, wherein the method comprises the steps of monitoring a frequency parameter and comparing it with a frequency set point, as to select a low or high frequency event and determining a power reference to the a least one wind turbine generator, based on the frequency parameter, In case a high frequency event is detected, the power reference is determined as a minimum of a selection of at least a first and a second minimum power reference. And in case a low frequency event is detected, the power reference is determined as a maximum of a selection of at least a first and a second maximum power reference, dispatching the power reference to the at least one wind turbine generator. The invention also relates to a wind power plant operating according to the method.
