The Power System Simulator of Tomorrow

Power grids are undergoing dramatic increases in complexity as we evolve from traditional, centralized power generation and radial distribution to 21st century grids featuring highly meshed networks, new HVDC interconnections, distributed energy resources (DER) and smart technologies.

HYPERSIM gives engineers the tools to tackle these challenges by providing a range of solvers and toolboxes specifically tailored to match the strictest performance and accuracy requirements in an extensive range of applications. With its efficient signal processing and powerful test automation capabilities, HYPERSIM helps engineers to model their network and run accelerated simulations on their personal computer before going to real-time for large-scale Hardware-in-the-Loop (HIL) testing.


HYPERSIM is state-of-the-art and extensively field-tested for both power electronics and power systems. Its open, flexible and scalable architecture and high-speed parallel processing enable the most demanding utilities, manufacturers and research centers to run faster, more realistic tests in order to meet the rapidly evolving requirements of the energy sector.
