Modelling switches in PGM

[PowerIsKnowledgeOrSomething]

Hello! I'm currently mapping power flow data from CSV files into PGM using Tabular Conversion, so far nodes, loads, lines, and transformers have been mapped, but I am having trouble modelling my switches. I've had a look through the information on component types in PGM, but cant seem to find a straight forward answer for switching types. Any advice would be much appreciated,
Sincerely,
Caleb

Hi @PowerIsKnowledgeOrSomething,

It should be possible to use the link component in PGM for that. It has two sides that you can use to switch: from_status and to_status enabling both results in the ON state, while setting one to 0 yields a disconnected OFF switch state.

Hope this answers your question.

Hi @PowerIsKnowledgeOrSomething,

You can indeed use links as @mgovers mentioned if you want to have specific switching components in PGM. However, for numerical stability it would be beneficial to have as little links as possible.

A better implementation would be to translate the switch status to the from_status or to_status of the specific branch (link, line, transformer). For example:

Your data: node1 - switch1 - line - switch2 - node2
PGM: node1 - line - node2

Where you can set the status of switch1 in from_status and the status of switch2 in to_status of your line (if from_node is node1 and to_node is node2; else, it will be the other way around)

Ok thanks!
