Effect of DG connection point on the voltage sag magnitude and duration at bus 15.
| Connection bus of DG | FSIG | DFIG | PMSG | Synch | | UPF |
| Minimum voltage sag (0.71 pu without DG) | 15 | 0.713 | 0.746 | 0.729 | 0.767 | 0.746 | 13 | 0.713 | 0.739 | 0.724 | 0.753 | 0.734 | 11 | 0.714 | 0.735 | 0.723 | 0.746 | 0.729 | 9 | 0.715 | 0.731 | 0.722 | 0.739 | 0.725 |
| Voltage sag duration (9.66 sec without DG) | 15 | 8.95 | 6.95 | 7.95 | 6.96 | 8.66 | 13 | 9.04 | 7.29 | 8.22 | 7.32 | 8.78 | 11 | 9.08 | 7.48 | 8.36 | 7.47 | 8.81 | 9 | 9.14 | 7.69 | 8.51 | 7.66 | 8.88 |
