RUNDUOPF Runs a DC optimal power flow with unit-decommitment heuristic. [RESULTS, SUCCESS] = RUNDUOPF(CASEDATA, MPOPT, FNAME, SOLVEDCASE) Runs a DC optimal power flow 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 struct 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 = runduopf; results = runduopf(casedata); results = runduopf(casedata, mpopt); results = runduopf(casedata, mpopt, fname); results = runduopf(casedata, mpopt, fname, solvedcase); [results, success] = runduopf(...); 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] = runduopf(...); Example: results = runduopf('case30'); See also RUNDCOPF, RUNUOPF.
