Fault current calculation in PSSEv34

In PSSEv34 or higher version, we can add distributed generation data in load. In fact, inverter-based generation resources will still contribute fault current although they connect to grid through power electronic components.

My question is, if I build a distributed generation resource in load data, does the fault current calculation of PSSE take this part into consideration? Thank you.

No, the distributed generation is not modelled as generation in short circuit calculation or in dynamic simulation.

The effective load is the normal load netted with the distributed generation.

Thanks for your answer. It will be a little annoying that if I want to take distributed generation's effect into consideration in fault current calculation, I have to build a machine data. Thus, I'm wondering if this function can simply my case, and I didn't find the relevant information neither.
