Abstract: The present invention relates to a method for increasing a total reactive power capability of a cluster of wind turbines operationally connected to a grid. The method comprises the steps of 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. Moreover, the present invention relates to a system suitable for carrying out the before-mentioned method.
