clustering strategies moved to configurables

[martacki]

Closes # (if applicable).
#375

Changes proposed in this Pull Request

all clustering strategies appearing in cluster_network or simplify_network now moved to configurables.
very recent changes from #379 missing again, but need to be placed in the config now, instead of in any of the scripts. (also, #379 forgot to make the adaptations in simplify_network)

Love it, some comments below. Could we add build_year, 'lifetime' and `efficiency'? Ideally with the functions as proposed here

pypsa-eur/scripts/cluster_network.py

Line 285 in bebbb00

'build_year': lambda x: 0, 'lifetime': lambda x: np.inf,

. But I don't know whether lamba's can be written in the yaml format...

and release notes of course

Second!

Could you also document the changes to the new and deleted config options here:

https://github.com/PyPSA/pypsa-eur/blob/master/doc/configtables/clustering.csv

and the removed potential option in

https://github.com/PyPSA/pypsa-eur/blob/master/doc/configtables/onwind.csv#L12

https://github.com/PyPSA/pypsa-eur/blob/master/doc/configtables/solar.csv

But the potential option is still needed for the build_renewables script, no?

You're right.

I think they cannot. But if we don't specify them, then PyPSA automatically will move to these defaults, so I wouldn't include it here. If you want to have a different aggregation, you can just add it now to your config.

LGTM.

[martacki]

Pls don't merge, found sth I forgot.

[fneum]

Great, just ping me when this is ready to be merged! Changes so far look good.

[martacki]

Sorry. I'll move duplicate code to _helpers script, because currently it's a 3x repetition
