IDX_DCLINE Defines constants for named column indices to dcline matrix. Example:
c = idx_dcline;
Some examples of usage, after defining the constants using the line above, are:
mpc.dcline(4, c.BR_STATUS) = 0; % take branch 4 out of service The index, name and meaning of each column of the branch matrix is given below:
columns 1-17 must be included in input matrix (in case file) 1 F_BUS f, "from" bus number 2 T_BUS t, "to" bus number 3 BR_STATUS initial branch status, 1 - in service, 0 - out of service 4 PF MW flow at "from" bus ("from" -> "to") 5 PT MW flow at "to" bus ("from" -> "to") 6 QF MVAr injection at "from" bus ("from" -> "to") 7 QT MVAr injection at "to" bus ("from" -> "to") 8 VF voltage setpoint at "from" bus (p.u.) 9 VT voltage setpoint at "to" bus (p.u.) 10 PMIN lower limit on PF (MW flow at "from" end) 11 PMAX upper limit on PF (MW flow at "from" end) 12 QMINF lower limit on MVAr injection at "from" bus 13 QMAXF upper limit on MVAr injection at "from" bus 14 QMINT lower limit on MVAr injection at "to" bus 15 QMAXT upper limit on MVAr injection at "to" bus 16 LOSS0 constant term of linear loss function (MW) 17 LOSS1 linear term of linear loss function (MW/MW) (loss = LOSS0 + LOSS1 * PF)
columns 18-23 are added to matrix after OPF solution they are typically not present in the input matrix (assume OPF objective function has units, u) 18 MU_PMIN Kuhn-Tucker multiplier on lower flow lim at "from" bus (u/MW) 19 MU_PMAX Kuhn-Tucker multiplier on upper flow lim at "from" bus (u/MW) 20 MU_QMINF Kuhn-Tucker multiplier on lower VAr lim at "from" bus (u/MVAr) 21 MU_QMAXF Kuhn-Tucker multiplier on upper VAr lim at "from" bus (u/MVAr) 22 MU_QMINT Kuhn-Tucker multiplier on lower VAr lim at "to" bus (u/MVAr) 23 MU_QMAXT Kuhn-Tucker multiplier on upper VAr lim at "to" bus (u/MVAr)
