Total generation and power load

Hello,

When I use B (bus based reports on a subsystem) it gives a lot of summarized info like this:

                    X------ ACTUAL ------X X----- NOMINAL ------X
                            MW        MVAR         MW        MVAR
                    FROM GENERATION               57.4     -174.9        57.4     -174.9
                    TO CONSTANT POWER LOAD       166.0       56.1       166.0       56.1

Is there a way in Python to obtain exactly that values (57.4MW and 166MW) and export them in excel?

Use GENDAT and BUSDT2 to obtain the total PGEN and PLOAD at the bus.

EDIT:

I didn't find any API returning bus subsystem totals. However, it is possible to use API scal for this. Example: A bus subsystem defined with sid=0.

ierr, totals, moto = psspy.scal_4(0,0,0,[],[])

The totals for the selected subsystem are returned in a tuple. Here, totals[1] contains the total MW load and totals[2] the total MW generation. See PAG manual for the rest of the content in totals.

Is a subsystem, many buses and generators, so I need a python function that returns the sum of the power of generators in that subsystem... exactly what the B button does

thank you. I managed to obtain the exact value.

can you share your solution?

psspy.bsysrcl(0,r"""mysubsystem.sbsxml""")
psspy.subs(0,0)
ierr,totals,moto=psspy.scal_2(0,0,1,[0,0,0,0,0],[0.0,0.0,0.0,0.0,0.0,0.0,0.0])
psspy.scal_2(0,0,2,[0,0,0,0,0],[0.0,0.0,0.0,0.0,0.0,0.0,0.0])
print "Subsystem Load", totals[1]
my PSSEv33 does't have scal_4
