Hi all, I have one question regarding branch index mapping between the extracted island and the original network. In particular, after I disable several lines, the network may break into islands. I solve dc power flow for each island. How can I relate the branch information in each island to the original network. It seems that internal and external indexing convert only works for bus index. Is there a straightforward way to do the branch mapping? Thanks a lot for your help.
Best, Yueyun
