Thanks a lot for the directions, then it was a misunderstanding about what “Committed Gens” are

I would simply set PMIN = PMAX = PG for the non-slack generators. The costs on the slack generators will determine how the slack is distributed.

The actual reason for this question: it was stated that it’s possible to achieve a “distributed slack” solution by means of running an OPF. In other words, I’m not very interested in “optimality”, but branch flow constraints as well as the “distributed slack” property of OPF are important. However, I’d like to distribute the slack not among all generators (how I could see in all sample data), but among few of them. Should I rise the costs for the “non-slack” generators or there is an explicit way to specify Committed Gens? Thanks, Ilya
