Add connections between electrical neighbours

[ClaraBuettner]

Comparable to the lines between Germany and its electrical neighbours, the electrical neighbours will be connected between themselves.

Up to now, I researched the number and voltage level of crossing lines using entsoe grid map.
When I connected Germany to its electrical neighbours, I used a dissertation (Electricity without borders) to find the cross-border capacitys.
The total capacity of all lines crossing a border in entsoe grid map is always higher than the cross border capacity in the dissertation.
So I would add the lines from entsoe grid map, is that all right?

I started writing a script which connects electrical neighbours automatically, including Germany and connections between other countries.
For AC-lines it works well but there are DC-lines as well.
The last time, I changed the 400kVDC connection to Sweden into a 380kVAC line. Now there are more DC-lines. Shall I change them too or add a link-table for them?

Hi @ClaraBuettner,
do you mean status quo or future Powerline projects?
The official overview of the status quo grid can be seen here:
https://www.entsoe.eu/map/Pages/default.aspx
Are those new DC lines part of the ENTSO-E Map?
@ulfmueller what do you think?

[ClaraBuettner]

I mean status quo, the entsoe grid shows for example a DC connection between Denmark and Sweden.

The new script for electrical neighbours is uploaded in feature/electrical_neighbours branch.

In the last script I cheated and added the Sweden connection as AC line, but it's actually DC. Now, I could do it right and it would also be a good opportinuity to test DC-lines.

Line loading with DC-connection to Sweden

Line loading with AC-connection to Sweden
Now, both is possible, the pictures show line loading at the same snapshots. But I havn't thought the differences were so remarkable.

This feature needs to be included in the v0.3.1 version of the dataprocessing

@ClaraBuettner: In which branch did you include these adjustments?

[ClaraBuettner]

It ist in feature/electrical_neigbours. To run it, tables inculding data from entso-e a needed. Unfortunately, I lost them when my disk crashed. It needs some time to recreate them. When do you need this?

[IlkaCu]

We would like to include this in the next dp run, which is scheduled for beginning of February. Can you estimate how long it will take you to recreate that table?

[ClaraBuettner]

Hopefully I won't need more then a day. I'll try to do this as soon as possible. I imported the data from csv to tables the database. Is it possible to integrate this? It is just used as an input-table.
