DFIG sliding mode control fed by back-to-back PWM converter with DC-link voltage control for variable

Youcef BEKAKRA,Djilani BEN ATTOUS

Frontiers in Energy 2014, Volume 8, Issue 3,   Pages 345-354 doi: 10.1007/s11708-014-0330-x

Abstract: control of doubly fed induction generator (DFIG) with the rotor connected to the electric grid through a back-to-backpulse width modulation (PWM) converter for variable speed wind power generation.A proportional-integral-(PI) controller is used to keep the DC-link voltage constant for a back-to-backPWM converter.

Simulation of grid connection and maximum power point tracking control of brushless doubly-fed generator in wind power system

Hicham SERHOUD, Djilani BENATTOUS

Frontiers in Energy 2013, Volume 7, Issue 3,   Pages 380-387 doi: 10.1007/s11708-013-0252-z

Abstract: In this paper, based on the analysis of the mathematical model in a common synchronous reference frame of the brushless doubly-fed generator (BDFG), the grid connection strategy and maximum energy extraction control were both analyzed. Besides, the transient simulation of no-load model and generation model of the BDFG have been developed on the MATLAB/Simulink platform. The test results during cutting-in grid confirmed the good dynamic performance of grid synchronization and effective power control approach for the BDFG-based variable speed wind turbines.
