Generally, a wind turbine may have inferior reactive power dynamic performance where constant power control is adopted by a wind farm equipped with Doubly Fed Induction Generators (DFIGs). As a result, power system disturbance may incur grid faults where the wind farm cannot provide enough reactive power to the grid. This paper proposes a novel reactive power control strategy with centralized management for a wind farm. The real-time signal representing the voltage at a specified remote location a Point of Common Coupling (PCC) is taken into account as an increment of the given value of the reactive power before being transmitted into each wind turbine by the distributed communication networks.
