Python for IPSA (Power flow analysis)

[Debbie]

Hi there,
I am new to Python, and wondering if you could help me with python based coding for the IPSA (Power system analysis software). I have a electrical distribution network with generators, buses and loads, on which I am performing the load flow analysis every 1 hour for a period of 1 year. 

The code to perform instantaneous load/power flow analysis is given below. I need to modify it such that I can perform this load flow analysis every 1 hour for a period of 1 year. Please help.

from ipsa import *

ipsasys = IscInterface()
net = ipsasys.ReadFile("refinery.iif")
bok = net.DoLoadFlow();
if bok:
    busbars = net.GetBusbars()
    print "Load Flow results:"
    print ""
    print "BusName     Vmag(kV)"
    print "===================="
    for bus in busbars.itervalues():
        name = bus.GetName()
        vm = bus.GetVoltageMagnitudekV()
        res = "%-8s  %10.5f" % (name, vm)
        print res
else:
    print "Load Flow failed!"

Regards,
Debbie
