LCC-MMC HVDC/MTDC system about andes HOT 7 CLOSED

You will need to use PSCAD or EMTDC. I don't think ANDES can currently support simulating down to the switching level.

Does ANDES have an existing LCC model?

@YaeSakura1: Andes does not have an LCC model yet. You might be able to program the LCC model in Milano's book (Power System Modelling and Scripting) following the modeling examples.

I want to use ANDES to implement the AC/DC power flow problem of the LCC-VSC hybrid system, and then study the electromechanical transient.Don't need to simulating down to the switching level.

Hi @YaeSakura1 ,

I saw your work in progress about the LCC-VSC models in power flow. It seems to be in the right direction. Keep adding the equations, and you should be good to go.

One practice I noticed in your fork is that you changed default arguments or config values in the program. It is totally fine because it's your fork. Just want to remind you that these default arguments are "fallback", and you can always supply with your custom ones when calling, without having to change the code.

Hi @cuihantao ,
Thank you for your advice.
To build the LCC model, what variables and equations do I need to add?

And how do I call my newly added model?

Please tell me how I can provide custom parameters at call time without having to change the code or changed default arguments or config values in the program.
Are you saying that I changed the maximum number of iterations for power flow calculation to 35? ('max_iter', 35)
Thank you

Please refer to the documentation for adding new models. Specifically, you can go through Model Cookbook and read the code.

I will close the issue for now. If you have more specific ideas to discuss, please post it to Discussions.
