An Enhanced Control Procedure for that DVR to accomplish both LVRT and HVRT in the DFIG Wind Turbine
Journal of Physics: Conference Series, 2022 Abstract In general, Double Fed Induction Generator DFIG-driven wind turbines are extremely sensitive to fluctuations in the grid voltage. For enhancing DFIG wind turbines, this paper proposes an improved procedure for controlling Dynamic Voltage Restorer (DVR) to simultaneously perform both Low Voltage Ride Through (LVRT) and High ...

Coordinated Droop Control and Adaptive Model Predictive Control for Enhancing HVRT and Post-Event Recovery of Large-Scale Wind Farm [PDF]
IEEE Transactions on Sustainable Energy, 2021 The wind turbine (WT) terminal overvoltage during grid voltage swell events may result in tripping the WT and consequently threaten the secure operation of large-scale wind farms (WFs). In this paper, an optimal coordination of droop control and adaptive model predictive control (MPC) scheme is proposed to enhance the high-voltage ride-through (HVRT ...

Enhancing the HVRT and LVRT Capabilities of DFIG-based Wind Turbine in an Islanded Microgrid [PDF]
Engineering, Technology & Applied Science Research, 2017 Doubly fed induction generator (DFIG) based wind turbines are very sensitive to grid voltage variations. Therefore, low-voltage-ride-through (LVRT) and high-voltage-ride-through (HVRT) capabilities are employed to improve DFIG performance during grid faults and voltage swell events. In this paper, a superconducting magnetic energy storage (SMES) device
