Smart Sensors and Standard-based Interoperability in Smart Grids



Yuyin Song, Gerald J. FitzPatrick, Kang B. Lee


Smart grids (SGs) are electrical power grids that apply information, advanced networking, and real-time monitoring and control technologies to lower costs, save energy, and improve security, interoperability, and reliability. Smart sensors (SSs) can provide real-time data and status of the grids for real-time monitoring, protection, and control of grid operations. Sensor data exchange and interoperability are major challenges for SGs. This paper describes sensing, timing, intelligence, and communication requirements of sensors for SGs and proposes a general model of SSs for SGs based on these requirements. Then it illustrates how the model works with phasor measurement unit (PMU)- and merging unit (MU)-based SSs deployed in SGs with standardized interfaces to support the interoperability of SSs. Furthermore, to address the interoperability issues, the paper describes sensor interface standards used in SGs and the need for interoperability testing, and proposes a passive interoperability test method for SSs to achieve and assure sensor data interoperability. To verify this test method, an interoperability test system for PMU-based SSs was developed and is presented. Interoperability test results of eight commercial PMU-based SSs are provided to show that the proposed interoperability test method works.
