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.

So the total reactive loss in the line is the series loss minus the branch charging injection.
