An Analysis of Variable-Speed Wind Turbine Power-Control Methods with Fluctuating Wind Speed [PDF]

open access: yesEnergies, 2013
Variable-speed wind turbines (VSWTs) typically use a maximum power-point tracking (MPPT) method to optimize wind-energy acquisition. MPPT can be implemented by regulating the rotor speed or by adjusting the active power. The former, termed speed-control mode (SCM), employs a speed controller to regulate the rotor, while the latter, termed power-control
