The Power System Simulator of Tomorrow

With the shift from centralized power generation to a grid featuring distributed energy resources (DER), the electric power grid is undergoing considerable change. Along with the integration of smart technologies–all with the potential to provide advanced real-time monitoring, control, and protection capabilities–this shift has dramatically increased the complexity of power systems.

HYPERSIM® provides engineers with tools to address these challenges, through an advanced real-time simulation platform featuring Hardware-in-the-Loop (HIL) testing. Whether you’re developing, integrating or testing, or simply tired of waiting hours for a few seconds of simulation, HYPERSIM provides the solution.
