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: The invention relates to a method for controlling power generation of a power plant which comprises power generating units including a wind turbine. At least one power unit is operated in a non-controlled mode with a non-curtailed power set-point, and at least one other power unit is operated in a controlled mode with a curtailed power set-point. Positive capabilities are determined as the difference between the available power and the curtailed power production. The total positive capability is determined as the sum of positive capabilities. The proportion of the power units intended to be operated in the non-controlled mode is determined as a function of the total positive capability. Dependent on the difference between the determined proportion and an actual proportion the status from non-controlled mode to controlled mode, or vice versa, of one or more of the power units is changed.
