Using Grid Connected PUC Inverter With Robust Control Against Hybrid DG's Oscillation

In this paper, a packed U-cell inverter is used with predictive control in which uses hybrid distributed generators with output voltage oscillations. Since the converter is used in the grid-connected application, consequently low THD is needed in the point of common coupling (PCC). The distributed generators are different and each of them has considerable variations in their output terminal. So, using an improved configuration against these oscillation is necessary. Therefore, the PUC configuration is proposed for these applications. Distributed generators include fuel cell and PV that in the output terminal of each of them considerable oscillation could be generated.
