IIC Launches Smart‑Grid Testbed to Accelerate Green Energy Adoption

Introducing the IIC Smart Grid Initiative

Today the Industrial Internet Consortium (IIC) announced a bold step toward large‑scale green energy adoption: a microgrid testbed that will integrate real‑time intelligence across the grid.

Why Current Grids Fall Short

Traditional power systems update output estimates every 15 minutes, a cadence that cannot accommodate the variability of renewable sources or sudden high‑load events like electric‑vehicle charging. To prevent blackouts, operators keep reserve generators online, which burns fossil fuels and undermines renewable gains.

Microgrids as the Solution

By embedding intelligence at the field level, microgrids close control loops in milliseconds, not minutes. They harness local generation—solar panels, wind turbines—and practical storage such as capacitors and batteries, allowing rapid response to fluctuations.

The Field Message Bus

The backbone of a microgrid is a high‑performance “field message bus.” It links devices and intelligent nodes at gigabit speeds, while also communicating with the central station and cloud. This dual local‑remote architecture optimizes operations in real time.

Collaboration on the Communication and Control Testbed

The IIC’s first energy‑focused testbed, the Communication and Control Testbed for Microgrid Applications, brings together RTI, National Instruments, Cisco, CPS Energy, Southern California Edison, Duke Energy, and the Smart Grid Interoperability Panel (SGIP). The project will evaluate whether a data‑centric standard—DDS—can serve as the core of a microgrid‑based power architecture.

Proven Industry Adoption of DDS

DDS already powers critical grid infrastructure, from Siemens Wind Power’s largest turbines to North America’s largest hydropower dam. This testbed will scale the technology down to the smallest power systems, paving the way for a network of efficient microgrids that feed into a broader Industrial Internet of Things ecosystem.

Real‑World Validation

Southern California Edison’s advanced grid‑simulation laboratory will run initial trials, featuring full photovoltaic, central‑station, sub‑station, and transmission hardware, along with a “garage of the future” that includes electric vehicles. CPS Energy will conduct final field tests in its “Grid of the Future” neighborhood.

Alignment with Open Field Message Bus (OpenFMB)

Following Duke Energy’s 2024 reference architecture and SGIP’s codification of OpenFMB data models, the IIC is aligning its work to ensure industry compatibility and accelerate adoption.

Vision for a Connected, Greener Future

By standardizing generic, high‑bandwidth networking across industry, field, and cloud, the IIC is paving the way for sensor‑to‑cloud, power‑to‑factory, and road‑to‑hospital integration—an essential step toward a more efficient, greener world.
