Smart sensors play a critical role in smart grids, supporting bidirectional flows of energy. Such sensors are needed for real-time monitoring of energy flow; controlling power generation, transmission, and distribution to customers; and protecting the overall power systems.

However, the interoperability of smart sensors is an issue, due to the number of different manufacturers employing various interface protocols in their products.

To help address the interoperability issue, NIST researchers propose “A Methodology for Modeling Interoperability of Smart Sensors in Smart Grids,” recently published on IEEE Xplore. The modeling methodology is based on interactions, using labeled transition systems and finite-state process techniques to quantitatively and automatically measure and assess smart sensors’ interoperability. Any interoperability issues can be identified based on the assessment results, and ultimately resolved to improve sensor data interoperability in smart grids.
