idx_dcline

PURPOSE ^

IDX_DCLINE Defines constants for named column indices to dcline matrix.

SYNOPSIS ^

function c = idx_dcline

DESCRIPTION ^

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)
