Do different versions of PSS®E (e.g., v34 vs. v35) necessarily produce different power flow results for the same input case, even if the system model remains unchanged?

Hey everyone, I have notice that after comparison power of flow results from different versions of PSS/e has discrepancies. I would like to open a discussion to see if others have experienced this type of issue and to better understand the underlying reasons for these differences.

Try changing the settings "Current as MVA" to "MVA" or vice versa. From what I know, in a certain version the software calculates the opposite of what it should be
