My saved case has over 100 buses that are 500kV in a PSSE area (area 3). Finding all of the 500kV area 3 buses is easy using the filters on the PSSE user interface. But my question is how to find those bus numbers in Python?
I'd use the Subsystem Data Retrieval and Subsystem Definition APIs. Use these to create a subsystem of buses based on a filter, and then retrieve attributes like Voltage and Angle.
# filter all area 3, 500kV buses and put into subsystem 1.
psspy.bsys(
sid=1,
usekv=1, # filter based on Base kV
basekv=[500,500], # select buses with base voltage 500kV
numarea=1,
areas=[3], # only buses in area 3
)
# now get the bus numbers for buses in subsystem 1.
ierr, target_buses = psspy.abusint(
sid=1,
flag=1, # only in service buses.
string=["NUMBER", "TYPE"] # request bus numbers and types.
)
There is a lot more you can do with subsystem data retrieval functions (like abusint). Look at Chapter 8 of the PSSE Application Program Interface (API) manual.
