This paper proposes an optimized model and control strategy for variable speed wind turbine using permanent magnet synchronous generator (PMSG). Models and equations that describe different components of the wind energy conversion system (WECS) are addressed and their implementations into PSCAD/EMTDC are described. There are different types of synchronous generators, but the PMSG is chosen. It offers better performance due to higher efficiency and less maintenance since it does not need external DC source and can be used without a gearbox, which also implies a reduction of the weight of the nacelle and a reduction of costs. For the better performance, in this model two level IGBT converter and three level IGBT inverter set has been used associated with the maximum power point tracking (MPPT) system.Simulation results show that the controllers can extract maximum power and regulate the voltage and frequency under varying wind and load conditions. The controller shows very good dynamic, steady state and transient performance.
