Load Flow Blown up in Minimum Model

I am creating New Minimum Model for a large Network ( 30 G generation ). When I disconnect some generation according to the operation , I receive this msg Largest mismatch: 8797.01 MW 3476.87 Mvar 9459.17 MVA at bus 30962 [QTF115 115.00] System total absolute mismatch: 21182.42 MVA

and Power Flow is blown up. I try flat start it worked fine. Should I continue on this model or I need to fix the Mismatch on this bus?
