Mr. Ray Zimmerman Have a good day. I´ve a question about dcopf.Currently I am
doing Transmission Expanssion Planning using dcopf with MatPower.I did
forecasting demand, generator park with hidroelectric machines like thermic
machines.If exist lack energy in some busses an fictitious generator is going
to be operate to satisfy the demand. But the problem is than economic dispatch
only did it with hidroelectric machines and few thermal units. In spite of I´ve
some machines available. There are some posibilities in MatPower to use such
as:
11 - OPF_ALG, 0 algorithm to use for OPF
[ 0 - choose best default solver available in the following order, 500, 520
then 100/200 ]
[ Otherwise the first digit specifies the problem ]
[ formulation and the second specifies the solver, ]
[ as follows, (see the User's Manual for more details) ]
[ 100 - standard formulation (old), constr ]
[ 120 - standard formulation (old), dense LP ]
[ 140 - standard formulation (old), sparse LP (relaxed) ]
[ 160 - standard formulation (old), sparse LP (full) ]
[ 200 - CCV formulation (old), constr ]
[ 220 - CCV formulation (old), dense LP ]
[ 240 - CCV formulation (old), sparse LP (relaxed) ]
[ 260 - CCV formulation (old), sparse LP (full) ]
[ 500 - generalized formulation, MINOS ]
[ 520 - generalized formulation, fmincon ]
[ 540 - generalized formulation, PDIPM primal/dual interior point method ]
[ 545 - generalized formulation (except CCV), SCPDIPM step-controlled
primal/dual interior point method ]
[ 550 - generalized formulation, TRALM trust region based augmented Langrangian
method ]
So I´ve been used the next option.
mpoption(mpopt, 'PF_DC', 1);mpopt = mpoption(mpopt, 'OPF_ALG', 0);
I don´t know what is the function of each one of these.
I attach the next document where is the features of each machine and outcome of
one economic dispatch where there is other question. By your attention thanks
ahead. Byron Nuques.
