Abstract

Grid connected voltage source converters have become inevitable means for expanding and supporting power systems. In this paper, a combined method is adapted to the converter control of grid connected micro grids against multiple risks. A single control system is proposed to cope with high power fluctuations, short circuit faults, and unbalanced operations at the same time. It is realized by using the advantages of a current control scheme in connection with a smart converter switching logic. As a result, no extra means are needed for tackling each of the undesirable conditions. The control system provides stable operation and fault-rid through capability even under unbalanced conditions. It is presented with and without virtual flux calculations. The system operation under the proposed control system is compared with the one under a conventional control system to confirm its performance superiority.
