Dear Mr.Shree,
Thank you very much for your help. As per your suggestion and FAQ I tried
to find out the problems.
The results I got-
1) Fast-decoupled power flow did not converge in 30 iterations.
2) By following http://www.pserc.cornell.edu/matpower/#pfconvergence I
tried to runcpf to get
Unfortunately, I can’t say anything about the divergence of the power flow by
looking at the Jacobian spy plot. The Jacobian spy plot looks fine to me based
on how the equations and variables are ordered for MATPOWER’s power flow.
Please send me the test case (offline) and I’ll try to debug
