If the isolated portions have adequate generation to operate as an island, then the only thing necessary is to make sure that each island has its own reference bus. In your case, however, I suppose there are de-energized sections. MATPOWER does not automatically handle the de-energized sections, so you will have to extract the section that is still live using extract_islands() <http://www.pserc.cornell.edu//matpower/docs/ref/matpower6.0b2/extract_islands.html>, then only run the power flow on that island.
