Linkers to accommodate custom data

[davide-f]

Describe the feature you'd like to see

There is the need for easy way to integrate additional custom data of:

• [x] Power lines
• [x] Custom powerplants ( already available as custom_powerplants.csv )
• [x] Time series of demand
• [ ] Time series of renewable production

To integrate demand time series and renewable production the approach is now not easy: there is the need to create a nc file with the same characteristics of the GEGIS and atlite modules. That is everything but easy and needs to be improved.

One note from the PyPSA user meeting. We need to make this linkers as clear as possible such that people can:

• Easy understand and analyse the data status
• Add new data over simple interfaces
• Optional. Write instructions on how to contribute to global sustainable databases OpenStreetMap etc.

Adding a points for a particular use case (@davide-f, @AnasAlgarei, @pz-max thanks a lot for the discussion!). It can be needed to have at least one bus for each administrative region in case if gadm clustering is used. For some areas where OSM data seems to be incomplete, there may be need to add such buses. That may be the case, for example, for Colombia, Chile, Vietnam (picture from openinframap):

To keep the gadm areas interconnected, a custom csv can be fetched to add buses for the areas where they are missed. To create such csv, we need a code that checks for every gadm shape if a bus is already available, and if not stores the centroid of the bus in an additional file with the format matching the substation geojson. A branch or a notebook can be added to store such code.

As a more general solution, a function can be added to base_network, but it requires the additional input of gadm shapes.

Thanks to #842 lines and links are now fully supported

987 should cover the demand part.

@davide-f would you mind if I'll tick the demand box? 🙃

Agree :D

Agree :D

Thanks! A great feeling for Friday evening to get something actually done XD
