Abstract :
Permanent magnet synchronous generators (PMSGs) are commonly used as a variable speed generator in wind energy systems. This paper describes a maximum power point tracking (MPPT) scheme for a PMSG-based wind energy conversion system (WECS) in which a buck-boost converter is used to handle a wide range of wind speeds. A closed-loop with a PWM inverter forces the WECS to extract the maximum power available from the wind turbine by shifting the phase angle of output voltage at a given wind speed. The output power is fed to the grid. The mathematical model of the wind power system is built and simulated by MATALB/SIMULINK software. Simulation results show that the proposed control scheme has a good dynamic performance and operates the wind generation system with the maximum efficiency.
