Simon, Thanks for the input.
Yes, Pmax for the generator at bus 1 is 35 MW, which is 15 MW short of being able to supply the load alone, but (leaving both online) in this substation emulation it is desirable to fully use its capacity as its connection to the load has the lowest impedance. I'm thinking that, even though they are being modeled as substation busbars, the generators' operating points might be limited by their capability curves, is that correct?
