Guideline for the Implementation of Coexistence for Low Frequency Narrowband Power Line Communication Standards in the Smart Grid



David H. Su


The Smart Grid Interoperability Panel (SGIP) was established by NIST to facilitate execution of tasks under the Energy Independence and Security Act (EISA) of 2007. The Priority Action Plan 15 (PAP 15 ) working group of the SGIP was established in 2009 to address the harmonization of new power line communications (PLC) standards and their coexistence specifications. This NISTIR presents PAP15’s recommendation to the SGIP on the implementation of coexistence mechanisms for narrowband PLC (NB-PLC) standards. This document also provides an introduction of NB-PLC standards and their coexistence mechanisms. NB-PLC standards define communication protocols operating below 500 kHz frequency with a bandwidth from tens to hundreds of kbps. The coexistence mechanism allows multiple devices of different technologies to coexist over the shared power lines.
