offshore capacity_per_sqkm #128

Open lindnemi opened 5 days ago

Edited:

I set some reasonable limits for offshore potential. However the value of capacity_per_sqkm is likely too high in the config. Need to discuss what's a good assumption

Previous issue: Onshore maximum of 160 GW (maximum target of Wind-an-Land Gesetz) Offshore ?

Relatedly capacity_per_sqkm has to be corrected

The default value for offwind is 2. There used to be an explanation for this value in the config, i just found it in the git history:

# ScholzPhd Tab 4.3.1: 10MW/km^2 and assuming 20% fraction of the already restricted
# area is available for installation of wind generators due to competing land use and likely public

I added the following limits:

offshore: 70GW onshore: 160GW solar: 400GW

ok with capacity_per_sqkm set to small values we do not have enough offshore potential in germany and run into infeasibilites i will leave it at 10 MW / km² and use the global constraint on wind capacity to limit expansion however this might indicate that the defaults for pypsa-eur are too low 🤔

interestingly high capacity per sqkm leads to more time spend in build_renewable_profiles
