runsdpopf

RUNSDPOPF  Runs a semidefinite relaxation of the AC optimal power flow.
   [RESULTS, SUCCESS] = RUNSDPOPF(CASEDATA, MPOPT, FNAME, SOLVEDCASE)

   Runs a semidefinite programming relaxation of the AC optimal power flow, 
   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 = runsdpopf;
       results = runsdpopf(casedata);
       results = runsdpopf(casedata, mpopt);
       results = runsdpopf(casedata, mpopt, fname);
       results = runsdpopf(casedata, mpopt, fname, solvedcase);
       [results, success] = runsdpopf(...);

       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] = runsdpopf(...);

   Example:
       results = runsdpopf('case30');
