HYPERSIM 2025.4 released: Accelerating DER and grid-forming EMT studies

OPAL-RT has released HYPERSIM 2025.4, introducing new capabilities that simplify and accelerate real-time EMT studies for distributed energy resources (DERs), microgrids, and grid-forming systems.

This release adds six new renewable energy and grid-forming example models, providing ready-to-run reference systems for evaluating droop control, virtual synchronous generator (VSG), and multi-inverter interaction scenarios. These validated models reduce study setup time and support more consistent benchmarking of grid-forming and grid-following control strategies.

HYPERSIM 2025.4 also improves planning-to-real-time workflows through enhanced ePHASORSIM integration, including expanded import support for PowerFactory and PSS®E models. Additional updates include expanded support for multi-phase machine modeling, improvements to FPGA-based power electronics workflows, enhanced dashboards, and new OPAL-RT hardware support.

HYPERSIM 2025.4 is available in the OPAL-RT Download Center. Detailed information is available in the HYPERSIM 2025.4 release notes.
