I think Dave's suggestions are useful, a few years ago I was one of the
developers for the IPSA python API, I'm not sure how things have moved
on since then but you need somewhere to incorporate some time modelling
- at the moment I'm not sure how and if that was done. In any case I
doubt if the simulation would give rigourous results over a simulation
period of that length

Is what you really have  a set of iif files with current voltages over a
set of periods within that year, if so you need to iterate though those,
loading each one and doing individual load flows.

IPSA has a linkedin discussion group and current IPSA developers will I
think respond to you there (if you have an account)
