G.8 MINOPF – AC OPF Solver Based on MINOS
MINOPF  is a MINOS-based optimal power ﬂow solver for use with Matpower. It is
for educational and research use only. MINOS  is a legacy Fortran-based software
package, developed at the Systems Optimization Laboratory at Stanford University, for
solving large-scale optimization problems.
While MINOPF is often Matpower’s fastest AC OPF solver on small problems, as of
Matpower 4, it no longer becomes the default AC OPF solver when it is installed. It
can be selected manually by setting the opf.ac.solver option to 'MINOPF' (see help
mpoption for details).
Builds are available for Linux (32-bit), Mac OS X (PPC, Intel 32-bit) and Windows
(32-bit) at http://www.pserc.cornell.edu/minopf/.
