@FabianHofmann Some points still can be improved for the multi-decade optimisation, but I would be happy to pull a first beta version into the master branch and then work on the single features in separate smaller PR.

[lisazeyen]

@FabianHofmann CI should run through once PyPSA/PyPSA#721 is in. There is a problem if the optimisation is multi-decade and the list of extendable lines or DC links is empty when selecting the active assets of an empty list.

@FabianHofmann, what do you think, can we merge?

[FabianHofmann]

I would be much in favour to merge it. Here some last remaining comments and the CI should run through. Otherwise, it looks great!

[lisazeyen]

@FabianHofmann thanks for your feedack!
CI is running through with the latest PyPSA Version, only the building of the documentation fails. I addressed your points above

[FabianHofmann]

Nice, let's go for it!
