1. A method of controlling power generation from a power plant which comprises a plurality of power generating units including at least one wind turbine generator, where the power plant is connected to an electrical power grid for supplying power from the power generating units to the electrical power grid, and where the power generating units are controllable to produce power dependent on individual power set-points, the method comprising:
obtaining desired target power set-points for one or more prioritized power generating units, wherein the desired target power set-points set a desired power on specific ones of the 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 desired target power set-points and an available power adjustment margin of the power plant which is available for adjustment of the desired target power set-points of the one or more prioritized power generating units, wherein determining the final target power set-points for the one or more prioritized power generating units is subject to a constraint of a power plant reference; and
dispatching the final target power set-points to the prioritized power generating units.
