Hello everyone!
Is there a dedicated command that returns the total Pgen/Pmax/Pload for a certain owner in a specific "area"?
For example: to sum in area number 6 all the existing Pgen production for a certain owner. If there is no such command, what is the shortest way to do it?
Thanks in advance.
Here is a nice function returning the total for a specified subsystem:
def subssum(areas=[], zones=[], owners=[], buses=[], kv=[]):
""" Returns total Pgen, Pmax and %-loading for generators in a subsystem"""
kvopt = 0 if len(kv)==0 else 1
psspy.bsys(11,kvopt,kv,len(areas),areas,len(buses),buses,len(owners),owners,len(zones),zones)
ierr, pgen = psspy.amachreal(11, 1, 'PGEN')
ierr, pmax = psspy.amachreal(11, 1, 'PMAX')
if pgen is None: pgen = [[]]
if pmax is None: pmax = [[]]
pgtot = sum(pgen[0])
pmtot = sum(pmax[0])
pct = pgtot/pmtot*100 if pmtot > 0 else 0
return pgtot, pmtot, pct
For example in savnw network the following returns the total for area 1 and 2 and owner 22:
pgtot, pmaxtot, pct = subssum(areas=[1,2],owners=[22])
In the end I found something like this:
thanks!

In a python script, open case and extract bus data and generator data into lists. Get the area and owner data in the bus data list for every generator bus and zip them to the generator data list. Finally, in a loop, select generator data for the target owner and area and add MW and MVAR into corresponding total.
