GridSim Studio – Grid Simulation Software for Real-Time Grid Emulation
GridSim Studio is Impedyme's dedicated grid simulation software for configuring, controlling, and visualizing real-time grid emulation on the CHP Series Grid Emulator platform. It turns complex PHIL tests into an intuitive, lab-ready workflow for engineers working on next-generation power and smart-grid systems.
By combining FPGA-based real-time simulation, regenerative power hardware, and a rich graphical interface, this real-time grid simulation software lets you bring realistic AC and DC grid behavior into the lab safely, repeatably, and at scale.
What Is GridSim Studio?
GridSim Studio is a powerful and intuitive grid simulation software environment designed to configure, operate, and visualize real-time grid emulation scenarios. It is a core component of Impedyme's CHP (Combined HIL and Power HIL) platform, enabling seamless control of advanced grid-tied power electronics testing environments.
Think of GridSim Studio as the brain and the face of Impedyme's grid emulator ecosystem. The underlying CHP hardware — built around high-speed FPGAs and DSPs — handles the raw computational muscle, executing real-time calculations at nanosecond-level precision. The grid simulator software sits on top of this hardware layer, giving engineers a sophisticated yet accessible interface to design, configure, control, and monitor every aspect of a grid emulation scenario.
This architecture is critically important. Separating the control software from the hardware means an engineer does not need to be a firmware expert or an FPGA programmer to run a complex, high-fidelity grid simulation. The interface organizes reference settings, voltage sources, current sources, grid impedance models, harmonic injection, protection systems, and real-time voltage preview into clearly labeled panels — all controllable from a single screen.

Why GridSim Studio Represents the Next Generation of Grid Testing
With Impedyme's grid emulator and GridSim Studio, engineers can create, control, and test real-world grid and motor conditions — virtually, safely, and in real time. This last word — safely — is worth dwelling on. Testing power electronics under fault conditions, voltage extremes, and resonance scenarios on a real grid would be genuinely dangerous and potentially destructive. This grid simulation software makes it possible to run exactly those scenarios in a controlled, repeatable, and safe laboratory environment.
For engineers developing and validating next-generation power converters, GridSim Studio bridges the gap between simulation and field testing — bringing full-fidelity grid behavior directly into the laboratory.
The underlying philosophy of GridSim Studio reflects a deep understanding of what modern power electronics engineers actually need: not just more raw power in a test setup, but more intelligence, more realism, and more confidence. The combination of FPGA-speed real-time processing, intuitive visual controls, standards-compliant automated test sequences, grid impedance modeling, harmonic injection, and seamless MATLAB/Simulink integration makes GridSim Studio a genuinely comprehensive platform — one that can accompany a product from early research and control design all the way through to final certification.
As power grids worldwide become more complex — with higher penetration of renewables, more distributed energy resources, greater dependence on power electronics, and tighter regulatory requirements — the tools used to validate grid-connected equipment must rise to meet that complexity. GridSim Studio by Impedyme is exactly the kind of tool the industry needs: rigorous, flexible, intelligent, and built by engineers who understand both the physics of power systems and the practical realities of the test laboratory.
