Doubly fed induction generator (DFIG) based wind turbines are most employed for onshore applications because of their cost-effectiveness. The drivetrain improvement is barely studied due to the maturity DFIG systems. This paper investigates two methods improving annual energy production (AEP) turbines. They referred as short-circuited and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/M...
