Claim Text:
1. A method of determining individual set points in a power plant controller arranged to control a wind power plant comprising one or more wind turbine generators and optional compensation equipment capable of generating electrical output, the individual set points relating to active and/or reactive power to be requested from each of the one or more wind turbines and the optional compensation equipment for delivery to an external electrical grid, the method comprising the steps of: a) receiving a request for active and/or reactive power to be delivered to the external electrical grid; b) determining the available active and reactive power from the at least one wind turbine generators and from the optional compensation equipment; c) comparing the requested active power with said determined available active power and/or comparing the requested reactive power with said determined available reactive power; and d) in the case where the comparison in step c) shows that the requested active power is less than the determined available active power and/or the requested reactive power is less than the determined available reactive power, determining individual setpoints for the at least one wind turbine generator and compensation equipment, wherein the determination of said individual setpoints is a combined calculation of optimised individual setpoints for the active power and reactive power from the at least one wind turbine generator and compensation equipment by use of information on the internal electrical grid in the wind power plant.
