I run PF for case 57 by removing line between 8 and 9 while the power flow is converging the reactive limit of generator at bus 9 violated. results.success ans = 1 results.gen(:,1:5) ans = 1 511.91 142.3 200 -140 2 0 -1.9005 50 -17 3 40 16.317 60 -10 6 0 6.774 25 -8 8 450 34.892 200 -140 9 0 86.611 9 -3 12 310 151.03 155 -150 ************************************************************************************** The contents of this e-mail message and any attachments are confidential and are intended solely for the addressee.
