Dear all, I'm starting to use the MOST software and I was trying to launch a simple test case that was already working with Matpower (DC OPF)
The test case is constitue of 42 buses with 37 loads, 1 generator and 61 lines. The only difference between the test case that I run in matpower and in MOST is the insertion of a simple load profile in the 37 buses. *""""""""""* *function loadprofile = load_profile* *[CT_LABEL, CT_PROB, CT_TABLE, CT_TBUS, CT_TGEN, CT_TBRCH, CT_TAREABUS, ...* * CT_TAREAGEN, CT_TAREABRCH, CT_ROW, CT_COL, CT_CHGTYPE, CT_REP, ...* * CT_REL, CT_ADD, CT_NEWVAL, CT_TLOAD, CT_TAREALOAD, CT_LOAD_ALL_PQ, ...* * CT_LOAD_FIX_PQ, CT_LOAD_DIS_PQ, CT_LOAD_ALL_P, CT_LOAD_FIX_P, ...* * CT_LOAD_DIS_P, CT_TGENCOST, CT_TAREAGENCOST, CT_MODCOST_F, ...* * CT_MODCOST_X] = idx_ct;* *loadprofile = struct( ...* * 'type', 'mpcData', ...* * 'table', CT_TLOAD, ...* * 'rows', [2 3 4 5 6 7 8 9 10 11 12 14 15 16 17 18 20 21 22 24 25 26 27 28 29 30 32 33 34 35 36 37 38 39 40 41 42], ...* * 'col', CT_LOAD_ALL_PQ, ...* * 'chgtype', CT_REP, ...* * 'values', [] );* *loadprofile.values(:, 1, :) = [* *1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62 1.62;* *2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16 2.16; * *""""""""""* I run the DC OPF with the MIPS solver, which gives a correct and reasonable solution when using it with matpower.
