Feature Request: Disconnecting a bus from the network
Thank you for your great work on this project! Could you please let me know if there are plans to implement a feature for completely disconnecting a bus from the network with one-sided disconnection of the connected branches? This is very useful for analyzing the actions of the breaker failure protection? Best regards,
Hi,
If I understand correctly, this feature requires the bus to have a status indicating whether it is in or out of service. Alternatively, are you suggesting the possibility of having breakers at both ends of the branch?
In either case, the solution involves treating the switch as a new component, which is not currently the case, with its own addSwitch! function. Consequently, it would also require dedicated update functions throughout the analyses.
I agree that this feature would be useful, and thank you for bringing it up. However, at this moment, I am unsure when or within what timeframe all these features will be implemented. Nevertheless, we will definitely be working on this.
Hi,
Yes, you're absolutely right — the feature would indeed require that each bus has a status indicating whether it is in service or out of service.
I don't know the implementation details, but I was thinking that a possible approach could be to represent switches as branches with zero impedance. Then, during the power flow calculation, these branches could be excluded and the corresponding buses merged. This way, it would also be possible to model breakers at both ends of a branch.
Thank you again for considering this idea!
I understand what needs to be done. The first step is to add support for algorithms to handle isolated buses, which is currently not implemented. I’ll keep the request open and provide updates as we make progress.
