If your are running ACPF simply change that value and the limits:
from: 39 1000 78.4674 300 -100 1.03 100 1 1100 0 0 0 0 0 0 0 0 0 0 0 0; to: 39 500 78.4674 300 -100 1.03 100 1 500 0 0 0 0 0 0 0 0 0 0 0 0; Those 500MW will be generated by the slack bus. 2014-04-12 12:53 GMT-05:00 Mahmoud Abdallah <[email protected]> : > > dear sir > I use matpower 3.2 > > I use runpf on case 39 and I wish to limit power generated at bus 39 to > certain value how can I do that ? > > first guess for power generated from generator at bus 39 = 1000 MW > I wish to make it generate only 500 MW > > thank you in advance > > > > > *Eng.
