Unfortunately, I do not have time to work on this myself. I was just giving a
suggestion for another direction to try if you want to understand the issue
that MATPOWER is having with your case. Could you post the output (using
verbose set to 2) of runpf() when using a MATPOIWER case file that corresponds
to the solved case from the Hadi Sadat code?
And if you have any questions about the MATPOWER case format or MATPOWER power
flow options, feel free to ask.
