Voltage regulation performance with different cases.

Voltage regulation method	Phase A	Phase B	Phase C
Case 1: unbalanced PV integration (25%, 30%, and 45%)
Constant power factor (0.9)	1.038	1.069	1.036
Power factor droop curve	1.041	1.065	1.043
Case 2: balanced PV integration (50%)
Constant power factor (0.9)	1.053 pu	1.054 pu	1.046 pu
Power factor droop curve	1.054 pu	1.054 pu	1.050 pu
