Latest Version | Psse

With IBRs (Inverter-Based Resources) replacing synchronous generators, older software versions produced inaccurate fault current results. Version 35.x introduces enhanced generic models for wind (WTG4) and solar (PVG2) that comply with new North American Electric Reliability Corporation (NERC) MOD standards. The latest version also includes native modeling for Type 5 wind turbines (full converter with grid-forming capability).

The latest release refines the modeling of Voltage Source Converter (VSC) based HVDC. It includes pre-built libraries for modular multi-level converters (MMC), allowing engineers to simulate multi-terminal HVDC grids (like those in the North Sea or Chinese grids) without workarounds. psse latest version
