HYPERSIM
HYPERSIM is the world’s most advanced real-time simulation platform for power systems, combining hardware-in-the-loop (HIL), software-in-the-loop (SIL), and offline simulation acceleration in a single, high-performance environment. As a leading power system real time simulator, our platform provides a robust environment for accurate power system simulation and power systems testing. Built by engineers for engineers, it empowers users to model, test, and validate complex electrical grids and inverter-based resource (IBR) integration with unmatched speed and precision.
Designed for system operators, asset owners, engineering firms, manufacturers, and researchers, HYPERSIM is also ideal for use in a power system simulation lab, replicating real-world conditions to de-risk new grid configurations and control strategies through flexible “what-if” scenarios—supporting everything from early design and commissioning to large-scale stability studies.
With seamless import from industry-standard tools, fast load-flow-based initialization, automated parallel processing, and a wide array of testing options, HYPERSIM accelerates innovation and enables grid planners and operators to boost system reliability, resilience, and performance—from early design to real-time operation.
