For example in case 33 buses, I will extract the subsystems from bar 2 to 22 (branches: 2-19 ; 19-20; 20-21 and 21-22). How would the mpc matrix be for such a situation?

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.

By performing load flow tests in IEEE radials feeders cases, such as 33, 69, 84 bars, I noticed that the study does not work when I leave isolated sections (eg in the case 33 buses, runpf('case33'), opening section 3-23 causes error). Is there any way in MATPOWER to perform load flow tests with isolated branches?
