“…However, more serious DC-link voltage drops occurred when the SDBR was implemented in DFIG-WTs compared with the SGSC and STATCOM. To improve the control effect of the SGSC, an adaptive resonant controller was proposed in Reference [59]. Through voltage distortion and unbalance compensation, the hybrid controller regulates the stator voltage at its rated value even under unbalanced grid voltage conditions.…”

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.

“…By using series voltage injection the SGSC can regulate the stator flux. The adaptive resonant controller is added to improve the controlling action of SGSC in reference [18]. With hybrid controllers, the stator voltages can regulate the voltage distortion and unbalance compensation under unbalanced voltage conditions.…”

“…Voltage‐unbalance is one of the most harmful disturbance in the power grid, which is mainly caused by asymmetry of line impedances, uneven distribution of single‐phase loads as well as various grid faults. Voltage‐unbalance increases the risk of insulation failure of the power lines, and results in over voltage, over current or power pulsations in electric equipment, which endangers the safety of the power grid as well as the electric facilities [1–3].…”
