For grid-connected DFIG-based wind turbine, Fault Ride Through (FRT) or Low Voltage (LVRT) capability is vital problem that need to be improved. This paper proposes an Active Disturbance Rejection Control (ADRC) strategy applied Doubly Fed Induction Generator (DFIG) based Wind turbine (WT), which integrates a Dynamic Restorer (DVR). The DVR connect in series the DFIG output terminal and utility...

In this study, robust and high-performance vector control of a rotor side converter (RSC) is performed for the stability efficient operation doubly fed induction generator (DFIG) based on variable speed wind turbine (VSWT). The mathematical model DFIG simulated by using Matlab/Simulink. amplitude frequency voltage in controlled different values load speeds. experimental DFIG-based system set up...

Variations in generator parameters that occur during the operation of a doubly-fed induction wind turbine (DFIG) constitute significant factor degradation control performance. To address problem difficulty identifying multiple simultaneously DFIG, parameter identification method depending on adaptive grey wolf algorithm with an information-sharing search strategy (ISIAGWO) is proposed to solve ...

In recent years, wind energy has become one of the most important and promising sources of renewable energy, which demands additional transmission capacity and better means of maintaining system reliability. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed spe...

With the prevalence of renewable energy sources such as wind power in system, analyzing fault characteristics systems composed DFIGs is becoming increasingly important. Therefore, this article analyzes, at first theoretically, a doubly fed induction generator (DFIG) during periods. It was found that current DFIG exhibited frequency offset phenomenon, which affected by depth voltage dips and can...

The strong coupling, multivariate, and nonlinear characteristics of the mathematical model a doubly-fed induction generator (DFIG) make it challenging to analyze bifurcation category DFIG. Therefore, in this study, we developed method for analyzing DFIG via topologically equivalent dimensionality reduction neighborhood values based on central manifold theorem realized discrimination Hopf type W...
