How to add multi country connected offshore hub?

[Heronimonimo]

I've been looking how to add an offshore hub that's connected to multiple countries. As far as I know the best route would be by forcibly adding a bus that is located at for example the Dogger Bank (https://en.wikipedia.org/wiki/Dogger_Bank). My goal is to see the total effect of:

• far offshore wind farm
• increased interconnection between countries

Do you have any advice on an elegant way to add this? For now my guess is to find a way to force a certain bus when clustering. But I'm not entirely sure.

I think, I'd add the hub in the base_network close to the call to _add_links_from_tyndp.

Don't let yourself be distracted by the clustering, it will not affect any links (DC), only lines (AC). The only function that might try to alter your hub is simplify_links in the simplify_network script.

In a slightly simplified explanation, it identifies small subgraphs that consist entirely of DC links and only connects to the ac network at two buses and replaces those subgraphs by single DC links and moves each component from a bus in between to its closer endpoint.

So, if you connect the hub to three endpoints the main condition is not satisfied and it should be left untouched, otherwise you would have to introduce some sort of extra column with which you want to label fixed lines and remove them from the adjacency_matrix at the top of simplify_links.

Check, that was helpfull input. I already added the links to the TYNDP, but did not add the bus location to buses.csv. After doing that it works!
