Hello,

Does anyone know what a negative load code means? In Load tab, there is a Code column. In my model, some of them have (-2) value. What does that mean?

Thanks a lot

The code is the bus code, 1=normal bus, 2=generator bus, 3=swing bus, 4= disconnected bus.

Generator buses with generator Qgen at a reactive power limit (Qmax or Qmin) are flagged with a minus sign in front of the bus code. I.e. -2 means a generator bus at a reactive limit and is thereby not able to control the bus voltage to the scheduled voltage.
