Dear Dr. Zimmerman,
We read the previous forum posts about load shedding and did as mentioned.
We multiplied load by a constant.
We also added generators Pg=0 and Qg=0 Pmax=0 Qmax=0 Pmin=-Pd,
Qmin=-Pd on busses where we have loads.
The generator cost function
a) 2 0 0 3 0 -60 0;
b) 2 0 0 3 0 -1000 0;
In both cases a) and b) we got, along with numerical values,
the following warning and errors:
Warning:

What might be the problem?
What do you advise?
Thank you for your help!
