This paper presents modelling, simulation and analysis of novel control strategies for variable speed wind turbines driven by a Permanent Magnet Synchronous Generators (PMSG) connected to the grid. The machine side controller is designed to match Maximum Power Point Tracking (MPPT) to obtain high extraction of wind power while connected to a the grid, and the grid side controller fixes the DC voltage that is converted to fixed 3-ph AC voltages and frequency. Main strategies of PI control and Model predictive control (MPC) have been discussed and compared to each other. Simulated voltage and current profiles are also presented in the paper in different cases of operation.
