Abstract

A method is provided for controlling the operation of a wind turbine includes (a) receiving an active power reference signal; (b) determining, based on the active power reference signal and an active power feedback signal, a first voltage control signal and a power controller frequency signal; (c) receiving a power reference signal; (d) determining, based on the power reference signal and the power feedback signal, a power offset frequency signal; (e) determining, based on the power controller frequency signal, a second voltage control signal; (f) determining, based on the power offset frequency signal, an angle signal indicative for an actual angle of a rotating dq reference frame; and (g) controlling the operation of a power converter based on the first voltage control signal, the second voltage control signal, and the angle signal.
