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
