I forgot that the GitHub version does not include the PDF of the updated
manual, only the source. Simply compile the LaTeX source found in
docs/src/MATPOWER-manual/MATPOWER-manual.tex. I’ll send you the PDF off-list in
case you don’t have a TeX compiler available.
To use the radial power flow algorithms, simply set the 'pf.alg' option to one
of the new values as mentioned in the CHANGES file, and call runpf() as usual.
The radial_pf() function is called by runpf() and is not intended to be called
directly, since it requires a case that has already been converted to internal
bus numbering and had unused branches and generators removed. There is no need
to modify anything in case33bw if you use runpf().
mpopt = mpoption('pf.alg', 'PQSUM');
r = runpf('case33bw', mpopt)
