idx_dcline

idx_dcline()
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 dcline 4 out of service

The index, name and meaning of each column of the dcline 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 dcline 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)
