The invention relates to a method for controlling power generation from a power plant which comprises power generating units such as wind turbine generators. The power generating units are controllable to produce power dependent on individual power set-points. The method comprises steps of obtaining desired target power set-points for one or more prioritized power generating units, determining final target power set-points for the one or more prioritized power generating units based on the target power set-points and an available power adjustment margin of the power plant which is available for adjustment of the power set-points of the one or more prioritized power generating units, and dispatching the final target power set-points to the prioritized power generating units.

Prioritization of power set-points for power generating units in a power plant

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.

Control of a power plant with at least one wind turbine

A wind power plant supplies power to a utility grid in accordance with an active power reference, where the wind power plant comprises a plurality of wind turbine generators and a power plant controller arranged to send an active power set point to the wind turbine controller of each of the plurality of wind turbine generators.

Wind power plant having a plurality of wind turbine generators and a power plant controller

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.
