Abstract :
This paper presents a simulation model of a MW-level variable speed wind turbine with a permanent magnet synchronous generator (PMSG) and a full-scale converter developed in the simulation tool of PSCAD/EMTDC. Grid connected wind turbines are fluctuating power sources during continuous operation. A novel wind power fluctuations mitigation method by DC-link voltage control of variable speed wind turbines is proposed in this paper. It smoothes the active power oscillations from the wind turbine due to wind shear and tower shadow effects by varying the DC link voltage of the full-scale converter. Simulation results demonstrate the validity of the proposed method.
