Hello everyone, I am trying to model a real power system that is quite complex. While I haven't been able to find data for every single load/generator/branch/etc. for the full system, I have begun by analyzing a simplified representation of the system where I have aggregated buses by their "zone" (the area of interest is subdivided into zones, and data is more readily available by zone than by individual bus). The idea is to represent each zone by a single "equivalent" bus.
My question is as follows: should I be declaring these aggregated buses as PV or PQ buses? In reality each zone has both generators and loads, so I'm unsure if a PQ bus or PV bus is more appropriate. If any of you could provide some insight into this problem it would be greatly appreciated. Regards, Danisz Stalinski
