[NEMO-devel] battery split

[Ben Elliston]

Hi all

Like the recent split of the pumped hydro generator into separate pump
and generator objects, I have done the same thing for batteries.
Instead of creating the battery like so:

batt = battery(17, 150, 2, "150MW, 2-hour li-ion battery")

you would do:

store = BatteryStorage(300, "300 MWh li-ion battery")
battery = Battery(17, 150, store, "150MW battery")
batteryload = BatteryLoad(17, 150, store, "150MW battery load")

(nb. batteries can now have different charging and discharging rates)

Both the battery and the battery load currently need to go into the
generators list. This will change soon!

Cheers,
Ben
