“…There are other two feedforward control methods that improve the transient capability of DFIG-WTs by adding feedforward terms: (1) feedforward current reference control (FCRC) was proposed to achieve zero-error tracking for the rotor current references after grid faults. By introducing the additional rotor current feedforward to the current loop, the rotor current can be maintained in a balanced and sinusoidal manner [71]; (2) feed-forward transient current control (FFTCC) was proposed to reduce transient current stress on the RSC and ensure that the active and reactive power supply remains uninterrupted by adding the stator flux-related feedforward components to the current loop [72].…”

In recent years, considerable advances were made in wind power generation. The growing penetration of wind power makes it necessary for wind turbines to maintain continuous operation during voltage dips, which is stated as the low-voltage ride-through (LVRT) capability. Doubly fed induction generator (DFIG)-based wind turbines (DFIG-WTs), which are widely used in wind power generation, are sensitive to disturbances from the power grid. Therefore, several kinds of protection circuits and control methods are applied to DFIG-WTs for LVRT capability enhancement. This paper gives a comprehensive review and evaluation of the proposed LVRT solutions used in DFIG-WTs, including external retrofit methods and internal control techniques. In addition, future trends of LVRT solutions are also discussed in this paper.

“…There is a certain degree of DFIG parameter deviation during grid faults. To emulate the condition of the actual DFIG parameter deviation in real time control, the DFIG parameters (L gf and R gf ) used in the control laws are varied, but the actual DFIG parameters (L * gf and R * gf) are unchanged [31]…”

A robust controller taking advantage of feedback linearization control (FLC) and sliding mode control (SMC) is proposed with an objective of mitigating the sub-synchronous control interaction (SSCI) in series-compensated doubly fed induction generator (DFIG)-based wind farms (WFs). FLC method is employed to obtain the reduced-order model of the studied system and, hence, smaller computation burden to controller design. Moreover, unlike linear control methods, FLC enables the controlled system to be independent of the pre-specified operations, which is suitable for highly nonlinear DFIG-based WFs. Considering that the FLC can be sensitive to parameter uncertainties, SMC is combined with the FLC to improve the robustness of the system. To evaluate the performance of the proposed feedback-linearized sliding mode controller (FLSMC) as compared to the conventional sub-synchronous resonance damping controller, the electromagnetic transient simulation and small-signal stability analysis are carried out. The designed FLSMC is observed to demonstrate the effectiveness in SSCI mitigation and robustness against the parameter perturbation at varied operating conditions. The experimental tests are performed to validate the veracity of the simulation results. * Superscript denoting reference value ω m , ω 1 Rotor shaft angular speed and system angular line frequency e q , e d ; u q , u d Grid voltage and PCC voltage u sc Voltage across series compensator i d , i q Current through transmissions u g , i g Voltage and current of the GSC loop C sc , R L , L L Compensator capacitance, network equivalent resistance, and inductance C dc DC-link capacitance S gq , S gd Switching signals for GSC
