PSSE 33.9 vs 33.10 Dynamics Simulation Results Mismatch
Hi,
I recently installed the latest PSSE 33.10 version. I previously was using 33.9 version. I found when I run the exact same dynamic simulation in each version the results are significantly different, with the 33.10 results going unstable and crashing the program but the simulations run fine in 33.9 and show no instability.
I am using the exact same cases, dyr data, same faults, clearing times, etc. I reviewed the release notes for 33.10 and none of the things I am using appeared to be affected by the updates in 33.10.
Is anyone else using PSSE version 33.10 for dynamics simulations and seen anything like this? I am wary that it is still an issue on my end that I haven't discovered but I thought it would be good to see if anyone else has seen this issue before I investigate further.
I would attach some sample plots of the dynamic results from both versions but I do not have the required points to do so.
