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

How many? How much? P (MW) Q (MVAr)
--------------------- ------------------- ------------- -----------------
Buses 9 Total Gen Capacity 820.0 -900.0 to 900.0
Generators 3 On-line Capacity 820.0 -900.0 to 900.0
Committed Gens 3 Generation (actual) 320.0 34.9
Loads 3 Load 315.0 115.0
Fixed 3 Fixed 315.0 115.0
Dispatchable 0 Dispatchable -0.0 of -0.0 -0.0
Shunts 0 Shunt (inj) -0.0 0.0
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.
