Abstract

Predictive current control is applied to a wind energy conversion system implemented with a permanent-magnet synchronous generator connected to the grid through a back-to-back neutral-point-clamped converter. This control approach allows to work in steady-state and to fulfill the low-voltage ride through requirements demanded by the power system operators. Dc-link neutral point voltage balance is also achieved by means of the predictive control algorithm.
