Abstract:
Methods for increasing a total reactive power capability of a cluster of wind turbines operationally connected to a grid and systems for carrying out the methods. The method includes generating a voltage value representative of a grid voltage level, determining a total required reactive power value based on the voltage value, and activating at least one wind turbine in said cluster to increase the total reactive power capability from a present value to the required total reactive power value by a predetermined amount.
