%???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.

%???????-?The?voltages?etc?in?[1]?appear?to?be?quite?close?to?the

%?????????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.
