AbstractAn increasing penetration of renewable power resources (particularly wind farms) is observed in power systems during the last years. There is a frequency control concern with these kinds of power resources because they do not provide the so-called inertial response. Since the doubly fed induction generator (DFIG) equipped with Variable Speed Wind Turbine (VSWT) is the mostly used type of generator in wind farms, this paper proposes a new control approach allowing the DFIG to participate more efficiently in the power system frequency control. The approach consists of three steps: (1) Estimating the active power mismatch ?P0 between the active electrical power and the mechanical power which appears at the first moment after the perturbance at the DFIG, (2) based on ?P0 determine the electrical power reference Pref of the active power controller, and (3) appropriate removal of ?P0 if the power frequency deviation is above a prescribed value and the automatic generation control (AGC) is activated. The obtained simulation results on a simple 2-bus system and on IEEE 14-bus test system show that the proposed approach has several advantages over existing approaches.
