Abstract
This paper introduces an improved strategy to increase the power production of wind turbines equipped with doubly fed induction generators (DFIGs) at low wind speed operation. The performance of DFIG-based wind turbines at low wind speeds, close to the cut in speed, is investigated. A modified control to extend the concept of maximum wind power tracking to cover the low wind speed region is implemented. The associated effects of the expanding technique are examined. Reasonable value for the dc link voltage is investigated. A comprehensive time-domain model for the wind turbine with DFIG and the decoupled dq controller are implemented using Matlab/Simulink software. Simulation results are included to ensure the validity and feasibility of the proposed modification for low wind speed operation.
