RUNUOPF Runs an optimal power flow with unit-decommitment heuristic.
[RESULTS, SUCCESS] = RUNUOPF(CASEDATA, MPOPT, FNAME, SOLVEDCASE)
Runs an optimal power flow (AC OPF by default) with a heuristic which
allows it to shut down "expensive" generators, optionally returning
a RESULTS struct and SUCCESS flag.
Inputs (all are optional):
CASEDATA : either a MATPOWER case struct or a string containing
the name of the file with the case data (default is 'case9')
(see also CASEFORMAT and LOADCASE)
MPOPT : MATPOWER options vector to override default options
can be used to specify the solution algorithm, output options
termination tolerances, and more (see also MPOPTION).
FNAME : name of a file to which the pretty-printed output will
be appended
SOLVEDCASE : name of file to which the solved case will be saved
in MATPOWER case format (M-file will be assumed unless the
specified name ends with '.mat')
Outputs (all are optional):
RESULTS : results struct, with the following fields:
(all fields from the input MATPOWER case, i.e. bus, branch,
gen, etc., but with solved voltages, power flows, etc.)
order - info used in external <-> internal data conversion
et - elapsed time in seconds
success - success flag, 1 = succeeded, 0 = failed
(additional OPF fields, see OPF for details)
SUCCESS : the success flag can additionally be returned as
a second output argument
Calling syntax options:
results = runuopf;
results = runuopf(casedata);
results = runuopf(casedata, mpopt);
results = runuopf(casedata, mpopt, fname);
results = runuopf(casedata, mpopt, fname, solvedcase);
[results, success] = runuopf(...);
Alternatively, for compatibility with previous versions of MATPOWER,
some of the results can be returned as individual output arguments:
[baseMVA, bus, gen, gencost, branch, f, success, et] = runuopf(...);
Example:
results = runuopf('case30');
