Dear Ray and others,   I have a basic question about the convergence/termination criteria. I want to run probabilistic power flow using AC solver and MIPS without any contingency. How do I decide the termination criteria? Or in other words, my OPF converges.   Sorry if it is a lame question.

Dear all,   I have a query regarding line real power in p.u. For any test case, say case30, the branch details are given in p.u. I was curios as how to calcuate the real line flow in p.u. Any pointers will be really helpful.   E.g. Line 3-4 in case 30, 3    4    0.01    0.04    0    130

Dear Ray/others,   I have a question regarding "transmat" value used in "most ex7 suc.m". Mainly, I'm confused with the values given in "ex_transmat(nt)":   T = [ 0.158655253931457; 0.682689492137086; 0.158655253931457 ]   Any pointers can be very helpful. Also, pardon for the naive
