not really. This is a very Matpower thing to do.

note to myself, include the change to ACBuses to use the available flag.

closed in favor of #48

@luke-kiernan in powernetwork matrices I have a sparse matrix addition that's optimized

> I fail to reproduce on `psy5`:  can we put these into a test please?

we can merge this but it isn't a requirement.

@scdhulipala you can try `jd/hvdc_area_fix` branch

Fixing this requires https://github.com/NREL-Sienna/InfrastructureSystems.jl/pull/457

this is now implemented in 88cc545 all that's needed now is to set `ENV["SIENNA_RANDOM_SEED"] = WHATEVER` at the top of the script

we can implement this already for 3.0 release of IS. Most of the use of `get_available` will be changed anyway in PNM and PF.
