Maximum allowable penetration ratio of the DGs units considering steady state voltage violation.
| Generator type | Number of units | Results comments |
| FSIG | Larger than 3 units | The min. admissible voltage regulation value is violated for max. loading condition. |
| DFIG, PMSG, and Synch with voltage control mode | 6 units | No admissible voltage violation for either max. or min. loading conditions. |
| DFIG, PMSG, and Synch with UPF mode | 1 unit | The max. admissible voltage regulation value is violated for min. loading condition. |
