Siemens often releases minor patches and "Service Packs" that adjust version numbers (e.g., v37.0.1). For the precise absolute latest sub-version number, users should log into the Siemens Support Center.
and the integration of modern renewable energy sources into the grid. Key advancements include: Gridscale X Integration : PSS®E has been integrated into the Siemens Gridscale X
If you are considering upgrading or purchasing a new license, it would be helpful to know: psse latest version
Previous versions (32-bit) were limited to 4 GB of RAM, causing crashes when simulating large networks (over 20,000 buses). is fully 64-bit, allowing access to terabytes of RAM. This means you can run:
| Feature | PSS/E v35 | DIgSILENT PowerFactory 2025 | PSCAD v5 | |--------|-----------|------------------------------|----------| | | No (only RMS) | No (only RMS) | Yes (native) | | Python API | Excellent | Good | Limited | | Renewable models | Very good | Excellent | Good | | Large system (>50k buses) | Excellent | Good | Poor | | User friendliness | Average | Good | Average | | Price (high to low) | Very High | High | Medium | Siemens often releases minor patches and "Service Packs"
: Highly recommended starting points include the PSSE Introduction to Dynamic Simulation for scripting and the Siemens PSSE Explore trial for students working on networks up to 50 buses [20, 23].
: PSS®E 36 continues to refine detailed substation topology modeling, moving beyond simple bus-branch representations to support the complex breaker-and-a-half or ring bus configurations standard in modern operations planning. Robust Core Performance Key advancements include: Gridscale X Integration : PSS®E
Some of the key features of PSS/E 35.4 include:
There is a verified incompatibility between a used by PSS®E. This conflict can cause PSS®E to instantly freeze or fail to launch entirely. PSS E – transmission planning and analysis - Siemens
I know what you’re thinking: "Upgrading our corporate simulation environment is a nightmare. Model conversion takes weeks."
