The microgrid integrated with utility operates in current-controlled mode and follows the utility''s operating point. In the study, the grid-connected microgrid is assumed to operate at a voltage of 1 p.u. and maintaining a frequency at 60 Hz. The islanding instance takes place at 1 s as can be analysed from Figure 6.
