makeYbus uses one-indexing about pypower HOT 4 CLOSED

The column bus[:, BUS_I] isn't necessarily a one-based index. It is a positive integer to identify the bus:

https://github.com/rwl/PYPOWER/blob/master/pypower/caseformat.py#L47

The ext2int function will convert to zero-based, consecutive indexing and int2ext will convert back again.

Bus 1 to bus 6 is not in the range of 0 to 5 man! That throws an error.

For running

Ybus, _, _ = makeYbus.makeYbus(thisCase["baseMVA"], thisCase["bus"], thisCase["branch"])

buses must appear in order by bus number

DC and AC power flows are working.

Why the FDPF can't take the regular case object ppc like the others?

ext2int

It's not very well documented.

Could you please update the fdpf() function to take a regular ppc object like opf() and dcpf()?

I believe the matpower version can.
