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

I assume you are referring to the “System Summary” part of the MATPOWER output?

Buses              9     Total Gen Capacity     820.0        -900.0 to 900.0

Branches           9     Losses (I^2 * Z)         4.95             51.31
Transformers       0     Branch Charging (inj)     -              131.4
Inter-ties         0     Total Inter-tie Flow     0.0               0.0
Areas              1


If so, please notice that series losses and the branch charging are listed 
separately. So the total reactive loss in the line is the series loss minus the 
branch charging injection.
