CASE39 Power flow data for 39 bus New England system.

SYNOPSIS ^

function mpc = case39

DESCRIPTION ^

CASE39 Power flow data for 39 bus New England system.
   Please see CASEFORMAT for details on the case file format.

   Data taken from [1] with the following modifications/additions:

       - renumbered gen buses consecutively (as in [2] and [4])
       - added Pmin = 0 for all gens
       - added Qmin, Qmax for gens at 31 & 39 (copied from gen at 35)
       - added Vg based on V in bus data (missing for bus 39)
       - added Vg, Pg, Pd, Qd at bus 39 from [2] (same in [4])
       - added Pmax at bus 39: Pmax = Pg + 100
       - added line flow limits and area data from [4]
       - added voltage limits, Vmax = 1.06, Vmin = 0.94
       - added identical quadratic generator costs
       - increased Pmax for gen at bus 34 from 308 to 508
         (assumed typo in [1], makes initial solved case feasible)
       - re-solved power flow
 
   Notes:
       - Bus 39, its generator and 2 connecting lines were added
         (by authors of [1]) to represent the interconnection with
         the rest of the eastern interconnect, and did not include
         Vg, Pg, Qg, Pd, Qd, Pmin, Pmax, Qmin or Qmax.
       - As the swing bus, bus 31 did not include and Q limits.
       - The voltages, etc in [1] appear to be quite close to the
         power flow solution of the case before adding bus 39 with
         it's generator and connecting branches, though the solution
         is not exact.
       - Explicit voltage setpoints for gen buses are not given, so
         they are taken from the bus data, however this results in two
         binding Q limits at buses 34 & 37, so the corresponding
         voltages have probably deviated from their original setpoints.
       - The generator locations and types are as follows:
           1   30      hydro
           2   31      nuke01
           3   32      nuke02
           4   33      fossil02
           5   34      fossil01
           6   35      nuke03
           7   36      fossil04
           8   37      nuke04
           9   38      nuke05
           10  39      interconnection to rest of US/Canada

   This is a solved power flow case, but it includes the following
   violations:
       - Pmax violated at bus 31: Pg = 677.87, Pmax = 646
       - Qmin violated at bus 37: Qg = -1.37,  Qmin = 0
