Distribution automation
The growing presence of distributed energy resources (DERs), microgrids, and electric vehicle (EV) charging is reshaping distribution networks—and adding complexity. Each system requires unique topologies and control strategies, pushing distribution system operators (DSOs) to adapt quickly while maintaining reliability. We support this evolution with hardware-in-the-loop (HIL) real-time simulation tools that reduce risk, shorten deployment times, and optimize automation. Our high-speed solvers and advanced hardware deliver precise real-time or accelerated simulations to validate protection systems, grid controllers, and communication protocols, minimizing downtime and enabling smarter, more resilient grids.

Advantages
The OPAL-RT edge
Our platform delivers key advantages for distribution management system real-time simulation.
Test fast DER controllers
Test high-frequency DER controllers combining sub-μs EMT simulation with a low-latency simulator architecture and fast I/Os, including full support for a wide range of communication protocols.
Exclusive IEEE 1547-compliant onverter control library
Gain a competitive edge with the world’s only smart inverter control library tailored for IEEE 1547. Validate interconnection performance, automate grid forming and grid support testing, and shorten time to market.
High-speed performance for complex models
When parallelization isn’t an option, raw processing power matters. Leverage cutting-edge Intel/AMD CPUs to run tightly coupled models with sub-50 µs time steps. Scale up with EMT-RMS co-simulation to model thousands of nodes while preserving fast dynamics where it counts.
Integration with industry tools
Accelerate your workflow by importing models directly from CYME, GridLAB-D, PowerFactory, and PSS®E. Preserve existing investments in planning and analysis tools while transitioning smoothly to real-time simulation and HIL testing—no need to rebuild from scratch.
Solution
Our solution for distribution automation
