Foundational Smart Grid Standards

The US National Institute of Standards and Technology (NIST) has advised the Federal Energy Regulatory Commission (FERC) that it has identified five "foundational" sets of standards for Smart Grid interoperability and cyber security that are ready for consideration by federal and state energy regulators. The standards, produced by the International Electrotechnical Commission (IEC), focus on the information models and protocols important to efficient and reliable grid operations as well as cyber security. The five families of IEC standards will further efforts to achieve efficient and secure intersystem communications, among other FERC priorities identified in the commission's July 16, 2009, Smart Grid Policy Statement.  These standards will be updated as Smart Grid requirements and technologies evolve. The standards and their functions are:     

  • IEC 61970 and IEC 61968: Providing a Common Information Model (CIM) necessary for exchanges of data between devices and networks, primarily in the transmission (IEC 61970) and distribution (IEC 61968) domains
  • IEC 61850: Facilitating  interoperability through a common data format as well as substation automation and communication
  • IEC 60870-6: Facilitating exchanges of information between control centers
  • IEC 62351:  Addressing cyber security of the communication protocols defined by the preceding IEC standards
