Abstract
A method for controlling power produced by a windfarm includes regulating active power produced by the windfarm in accordance with an apparent power setpoint, and regulating a power factor of the windfarm in accordance with a power factor setpoint. However, during periods in which the apparent power setpoint is approached or exceeded, the method includes reducing a magnitude of an angle of a power factor setpoint towards zero and regulating the power factor of the windfarm in accordance with the reduced power factor setpoint angle magnitude.
