1. Executive Summary

As of early 2024, the latest commercial release of Siemens Power System Simulator for Engineering (PSS®E) is Version 37.

Older versions required cumbersome workarounds (USER models or Python hacks) to simulate the "fast" dynamics of inverters. The new version introduces native GFM models that correctly simulate:
