Hi, I recently asked a question about islanding - how to make power flow functions work on such cases. Shri told me that I should determine isolated buses and set a reference bus for each island. I was doing exactly that and had no problems until I started running contingency analysis and faced this problem again. Now I have multiple cases for which RUNPF function does not converge. I am struggling with this problem for almost week and have tried everything. I am setting bus types correctly and have a reference bus for each island.
I would be incredibly grateful if somebody could suggest me where the issue may hide. I am also attaching a link to one of cases I am having troubles with in case it can be helpful (the file contains the case and a vector of bus areas (9 islands 7 of which a isolated buses)): https://www.dropbox.com/s/plmnk09qrv4dww0/problematic_case.m Thank you! ~Petr
