Abstract: A wind power plant has a plurality of wind turbine generators and a power plant controller arranged to communicate with the plurality of wind turbines generators. Each wind turbine generator has a controller arranged to control an active power output in its respective wind turbine generator according to an active power set point received from the wind power plant controller. A change in the active power reference changes the active power set point for each wind turbine generator by a weighting factor.

Abstract: Aspects of the present invention relate to a method for controlling one or more wind turbine generators. The method comprises: monitoring an electrical parameter of a power network to which the wind turbine generators are connected with respect to a deadband for the electrical parameter; and determining that the monitored electrical parameter is deviating outside of the deadband. In response to determining that the electrical parameter is deviating outside of the deadband, the method comprises: quantifying a severity of the deviation; and selectively implementing a parameter control mode when the quantified severity of the deviation is at or above a threshold level. In the parameter control mode, one or more power set points are determined based on the value of the electrical parameter and are dispatched to control the wind turbine generators.

Abstract: The invention relates to a method for correcting deviations of power produced by a power plant which includes at least one wind turbine generator and possibly other types of power generating units. The power deviations, i.e. deviations from a power reference for the power plant, are determined as energy errors. The invention addresses solutions for determining and compensating the energy errors.

Abstract: The invention relates to a method for determining power set points of a power plant comprising a plurality of power generating units with at least one wind turbine generator. The determination of the power set points are based on a prioritization of the power generating units, where the power generating units are prioritized with respect to individual power levels or fatigue levels obtained for the power generating units. The prioritization is adjusted so that the adjusted prioritization depends both on the power and fatigue levels.
