Standards are essential to meeting the needs of the Utility industry and energy consumers. Cisco strongly supports standards in all aspects of the Smart Grid. In the substation, Cisco currently participates in and contributes to the following areas of standardization.
The International Electrotechnical Commission (IEC) prepares and publishes international standards for electrical, electronic and related technologies. IEC's Technical Commitee 57's charter is to prepare standards for power systems. Among the Working Groups of TC 57, Cisco participates in Working Group (WG) 10 for Power system IED communication and associated data models (IEC 61850) and WG 15 for Data and communication Security (IEC 62351). In addition, Cisco participates in WG19 for Interoperability within TC 57 in the longer term.
The Institute of Electrical and Electronics Engineers (IEEE) is one of the leading standards making organizations in the world. Relevant to the electrical substation, the IEEE 1588 standards define ways to distribute precision timing over packet networks. Cisco is active in this standardization and have contributed to the new "Power Profile" of the 1588 standard. Cisco Connected Grid Switch (CGS) implements the new 1588 Power Profile.
The Internet Engineering Task Force (IETF) creates open standards that govern the Internet. Cisco is active in most areas of the IETF. In particular, Cisco promotes the following Internet protocols for smart grid communications.
IP multicast for Synchrophasor communications and other one-to-many and many-to-many communications applications
MPLS-TP to transition from legacy TDM architectures for teleprotection and low latency control applications
