Abstract
This article introduces a model predictive control (MPC) strategy for variable speed wind energy conversion system (VS_WECS) based permanent magnet synchronous generator (PMSG). The predictive control is applied for optimal operation of a PMSG wind turbine (WT). The PMSG is tied to the utility grid through a three-phase back-to-back (BTB) converter. The maximum power available from the WECS is harvested by applying the control algorithm to the machine side converter (MSC). The dc-link voltage regulation is achieved using the grid-side converter (GSC). A model of directly driven PMSG based variable-speed WECS is developed and imitated using MATLAB/SIMULINK environment. The MPC gives good dynamic performance under wide wind speed variation. The effectiveness of the proposed control approach is validated through extensive simulation results.
