MW_Mismatch Column
The difference between the total flow into the bus and the total flow out of the bus.
MW_Mismatch = total generation - total demand - net flows out of the bus
It should equal zero (0) in theory, so this output is intended for debugging purposes.
NOTE: A branch that has one bus in an area on OPF and one bus in an External area will normally have significant MW_Mismatch. This is a result of power flowing to or from a composite bus that is located in that External area.
