Dear all, I found this very useful post for network reduction: https://psspy.org/psse-help-forum/question/3588/constructing-a-short-circuit-equivalent/

The problem is that since it needs to convert the generator and loads to perform SCEQ, how do you later do a power flow with the reduced network?

Network reduction in PSSE is becoming a headache for me. I need to make sure the fault level at the boundaries remain more or less similar after the reduction while making sure the active power flows are more or less the same. I have done this manually before and I am trying to use PSSE's built in feature to automate it. For my applications, other reductions do not seem to be able to the job since the fault currents after reduction are very different from before.

Any idea? Thanks a lot
