Back-to-back Converter Control of Grid-connected Wind Turbine to Mitigate Voltage Drop Caused by Faults

open access: yes, 2017
Power electronic converters enable wind turbines, operating at variable speed, to generate electricity more efficiently. Among variable speed operating turbine generators, permanent magnetic synchronous generator (PMSG) has got more attentions due to low

Reactive Power Dispatch Method in Wind Farms to Improve the Lifetime of Power Converter Considering Wake Effect [PDF]

open access: yes, 2017
In Wind Farms (WF), the most popular and commonly implemented active power control method is the Maximum Power Point Tracking (MPPT). Due to the wake effect, the upstream Wind Turbine (WT) in WFs has more active power generation than the downstream WT at

Fault Diagnosis Methods Based on Fuzzy Logic and Artificial Neural Networks Approaches for Wind Turbine PWM Inverter

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This study explores fault diagnosis methods for PWM inverters in a wind energy conversion system using a doubly fed induction generator. Two intelligent diagnostic techniques, fuzzy resonant logic and artificial neural networks, are proposed. The fuzzy logic method monitors inverter faults in real time, whereas the neural network method uses 3D feature

Inertia emulation control strategy for VSC-HVDC transmission systems [PDF]

open access: yes, 2013
There is concern that the levels of inertia in power systems may decrease in the future, due to increased levels of energy being provided from renewable sources, which typically have little or no inertia.

Time‐Varying Inertia Estimation for Grid‐Connected DFIG‐Based Wind Farms Using Sensitivity‐Guided Clustering and Aggregation

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a time‐varying inertia estimation framework based on sensitivity‐guided clustering and aggregation. It can achieve high‐accuracy inertia estimation with limited measurements, reducing the relative error by nearly 10% compared with existing methods, and exhibit strong robustness to noise and disturbances.

Static analysis of voltage stability with DFIG

open access: yesScience and Technology Development Journal, 2016
The static voltage stability analysis is carried out by V-Q sensitivity or Q-V modal analysis. These analyses are based on the Jacobian matrix of power flow calculation. This is regarded as load bus stability analysis. With DFIG of PQ mode, the wind generation bus is considered as the PQ bus.

DFIG Model Suitable for SSR Research

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The simulation model of doubly fed induction generator (DFIG) is the basis of the research on subsynchronous resonance (SSR) of DFIG. In this paper, the conditions that the model of DFIG is suitable for the research of subsynchronous oscillation (SSO) are analyzed firstly. Then, the drive system, doubly fed induction motor, AC /

Active Low‐Voltage Ride‐Through Control Strategy for Wind Turbines to Improve Transient Stability in Power Systems

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
Based on the characteristic of wind turbine LVRT influencing system power balance, this study proposes a method utilising active LVRT control to achieve transient stability. A transient stability control strategy is developed by integrating active LVRT with deep reinforcement learning while introducing a disturbance‐level‐based coordinated control ...

Impact of Phase Locked Loop with Different Types and Control Dynamics on Resonance of DFIG System

open access: yesEnergies, 2020
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.
