SmartGrid Interoperability Standards are available online. Collected here are Smart Grid standards from the Smart Grid Interoperability Panel (SGIP) Catalog of Standards and the NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0 (pdf link). Given the nature and goal of interoperability, most of the standards presented here are part of both the SGIP and the NIST Framework. For further information, please visit the NIST SmartGrid site.

IEEE C37.118.1-2011

IEEE Standard for Synchrophasor Measurements for Power Systems

Synchronized phasor (synchrophasor) measurements for power systems are presented. This standard defines synchrophasors, frequency, and rate of change of frequency (ROCOF) measurement under all operating conditions.

IEEE C37.118.1a-2014

IEEE Standard for Synchrophasor Measurements for Power Systems -- Amendment 1: Modification of Selected Performance Requirements

Modifications in this amendment include some performance requirements with related text updates to correct inconsistencies and remove limitations introduced by IEEE Std C37.118.1(TM)-2011. It was discovered that a few requirements were not achievable with the published models as was intended and others were extremely difficult to meet with available hardware. This amendment modifies requirements in Table 4 through Table 10. Text was modified to support the requirement modification. Testing described in 5.5.9 was clarified, and Table 11 (formerly Table 12) was modified to match. Annex C was modified to keep it consistent with the rest of the document.

IEEE C37.118.2-2011

IEEE Standard for Synchrophasor Data Transfer for Power Systems

A method for real-time exchange of synchronized phasor measurement data between power system equipment is defined. This standard specifies messaging that can be used with any suitable communication protocol for real-time communication between phasor measurement units (PMU), phasor data concentrators (PDC), and other applications. It defines message types, contents, and use. Data types and formats are specified. A typical measurement system is described. Communication options and requirements are described in annexes.

IEEE C37.238-2017

IEEE Standard Profile for Use of IEEE 1588 Precision Time Protocol in Power System Applications

An extended profile is specified for the use of Precision Time Protocol of IEEE Std 1588-2008 in power system protection, control, automation, and data communication applications utilizing an Ethernet communications architecture.
