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
