Preventive Control Considering Stability Constraints for Repeated Low Voltage Ride Through Events
This paper proposes a voltage stability preventive control strategy that accounts for repeated low‐voltage ride‐through characteristics. The method first partitions the system and constructs a short‐term voltage stability assessment index that effectively incorporates repetitive LVRT events, while offline generating a corresponding set of anticipated ...

An Accurate Forced Oscillation Location and Participation Assessment Method for DFIG Wind Turbine
With the integration of wind energy, the widely used doubly fed induction generator wind turbines (DFIG-WT) could induce Power System forced oscillations (FOs), which threaten the safety of power grid.

To enhance grid stability and resilience in high renewable energy scenarios, this research proposes a cascaded control optimization framework guided by a novel dynamic resilience metric. Validated on a representative Australian grid, the framework significantly reduced voltage overshoot and extended fault clearing times, offering a robust solution for ...

Wind energy conversion systems (WECSs) require robust and efficient control strategies to ensure optimal energy conversion. This study proposes a nonlinear and resilient control approach using a fractional‐order proportional integral‐ and fractional‐order proportional derivative (FOPI–FOPD) controller for direct power regulation of a doubly fed ...

Impact of Phase Locked Loop with Different Types and Control Dynamics on Resonance of DFIG System
In recent years, the doubly fed induction generator (DFIG) operates in a weak grid, rather than a strong grid due to the high proportion of wind energy into the power grid.

An Efficient Hybrid Islanding Detection Method for Microgrids Using Kalman Filter
Islanding condition gives rise to several problems in distributed generation networks, including power quality disturbances, equipment damage, interference with grid protection, and danger to the utility crews. To avoid islanding detection failure of the passive section in case of a close matching between islanded generation units and loads, the active

Sub-synchronous resonance (SSR) occurred in the power system with both Doubly Fed Induction Generators (DFIGs) and series-compensated lines. There have been several papers focusing on the analysis of such SSR phenomenon. To the authors' knowledge, the impacts of DFIG numbers are seldom considered in existing papers.

Supercritical Pitchfork Bifurcation of a Fractional‐Order Doubly‐Fed Induction Generator
ABSTRACT To address the problem of the chaos phenomenon caused by the parameter drift of a doubly‐fed induction generator (DFIG) due to a changing operating environment, a fractional‐order stator voltage/flux‐oriented control model is developed, and bifurcation theory and numerical simulations reveal that the chaos mechanism originates from ...
