This paper describes novel integration of wind energy conversion system to the grid through back to back
PWM voltage source converters to make variable speed operation possible. The studied system here is a variable speed
wind generation system based on Permanent Magnet Synchronous Generator (PMSG). Vector control of the machineside
converter (MSC) provides active power control of the machine while vector control of the grid side converter (GSC)
keeps the voltage of the DC link constant and provides reactive power control of the grid. This paper considers the
Simulink/matlab simulation for DC link voltage control andreactive power control of grid connected PMSG and
corresponding results and waveforms are displayed. The machine side converter control is also explained in this paper.
