How to convert PSCAD model to PSS/E model? for example MMC-HVDC
In PSS/E, there is the HVDCPL1 model, based on Siemens HVDC Plus technology, which is MMC-HVDC.
This model is available in v34.2 of PSS/E; I can't confirm if it is in earlier versions.
Your challenge is to fit your PSCAD model to the HVDCPL1 model parameters - caveat utilitor!
Your first option should be to try to use the built-in PSS/E model "HVDCPL1", for which you do not need any external compiler or capability to write user-defined models. Purchasing a compiler and learning to write your own models is a significant money&time investment.
I would say that the most effective way to model an N-terminal VSC-HVDC system is to use N separate synchronous generators in power flow. Then, in a dynamic simulation, you will need to write a model with those N generators "talking" to each other.
