function mpc = case39
%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
