A new control scheme of back-to-back converter for wind energy technology

This paper proposes a new control scheme for a permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS). In this scheme, the generator and grid currents are controlled using a hysteresis current controller (HCC). The control system of the back-to-back converter based on the HCC is described. Modeling and simulation of the system are developed using Matlab/Simulink to validate the performance of the proposed current controllers.
