Abstract:
A variable speed wind turbine is arranged to provide additional electrical power to counteract non-periodic disturbances in an electrical grid. A controller monitors events indicating a need to increase the electrical output power from the wind turbine to the electrical grid. The controller is arranged to control the wind turbine as follows: after an indicating event has been detected, the wind turbine enters an overproduction period in which the electrical output power is increased, wherein the additional electrical output power is taken from kinetic energy stored in the rotor and without changing the operation of the wind turbine to a more efficient working point. When the rotational speed of the rotor reaches a minimum value, the wind turbine enters a recovery period to re-accelerate the rotor to the nominal rotational speed while further contributing to the stability of the electrical grid by outputting at least a predetermined minimum electrical power.

Claim (Index 6):
The wind turbine according to  claim 1 , wherein the controller is configured to accelerate the rotor when at least one of: the electrical grid is stabilized, the duration of the overproduction period where the electrical output power is increased reaches a time limit, and an amount of additional energy provided to the electrical grid during the overproduction period reaches a predefined limit.
