Comparison of Control Schemes of Wind Turbines with Doubly Fed Induction Generator

Other conference contribution, 2007

Validity of wind turbine model for power system stability studies has been important as the penetration of wind power generation in the power system increases significantly. Variable speed wind turbines with doubly fed induction generator (DFIG) are the most common technologies used in today’s wind power generation. So far, there is no agreement on generic model of this type of wind turbine. Different control schemes of wind turbine with DFIG have been presented in many publications. However, comparisons of the different control schemes and their influences on the stability study are rarely found in the papers. This paper investigates different control schemes implemented in wind turbine with DFIG for power stability studies, which include the speed/power controls and the pitch controls.
