PSS®E Latest Version: What’s New and Why It’s a Game-Changer for Power Systems

• Renewable Energy: Significant updates to generic renewable models (WECC and entso-e generic models) are included to better simulate solar, wind, and battery storage.
• Electromagnetic Transients (EMT): Continued improvements in the "PSS®E EMT" functionality allow users to perform EMT-level studies directly within the transient stability environment without needing to export to PSCAD, though the EMT feature often requires a specific license add-on.

2. The "Weak Grid" Study In the last version, if you ran a short circuit at a bus with 90% IBR penetration, the voltage recovery profile was wildly optimistic. Version 35’s new solver correctly models the "transient over-voltage" and "sub-synchronous control interactions" (SSCI) that have caused real-world inverter trips in Texas and the UK. psse latest version

Future Roadmap: What Comes After PSSE 35?

Siemens has quietly hinted at PSSE 36.0 (expected late 2025 or 2026). Rumored features include: PSS®E Latest Version: What’s New and Why It’s

   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:

   Built-in Model Converter: A new tool allows for the automatic conversion of existing dynamic model source code into the new Version 36 format, significantly reducing the manual effort required during upgrades.
