Abstract
The electrical supply grids can be the seat of an unbalance of voltage system following the single-phase loads which are connected and which are not uniformly distributed on the three phases. We propose, in the present paper a new approach to control a power system based on a double fed induction generator (DFIG) connected to an electrical grid likely to be affected of an unbalance voltage, via a back-to-back converter (AC/AC). The head aim is to guarantee a better quality of the energy exchanged between the power system and the unbalanced grid.
