Enhanced ZigBee Smart Energy

• Integration with ZigBee IP stack and PLC• Exploits the benefits of wireless and wired• Support for Forward-Thinking Developments

(PHEVs, Distributed Generation, etc.)• Working closely with IEC, EPRI, AHAM,

SAE, ESMIG, and others on requirements• Other Improvements based on

continuing feedback and Market needs

• One of the initial 16 on the NIST list for the Smart Grid

November 2009

Submission

• The United States Congress suggested it in relation to Stimulus Funding access and US utilities are now requiring it as part of their future networks.

• Offers alternatives not new capabilities• What will be in it?

– MAC – 15.4 2006 with MAC security– 6lowPAN packet format and fragmentation – ROLL routing– Plus other features essential to effective sensor

networks

Smart Energy 2.0 and ZigBee IP Background• US National Institute of Standards and Technology (NIST)

– Direction on standards selection• UCA International OpenSG

– OpenHAN System Requirements Specification (SRS)– Market Requirements Document (MRD) and Use Cases for Smart

Energy 2.0• ZigBee

– Developing IETF based IP stack for IEEE 802.15.4 based platforms based on OpenHAN SRS and Smart Energy 2.0 MRD

• HomePlug– Developing IEEE P1901 compliant powerline carrier solutions:

HomePlug AV and HomePlug SE• Recognized Standards Development Organizations (SDOs)

– IETF, IEC, IEEE, W3C

Submission

• Meets Smart Energy 2.0 MRD:– “Shall source existing standards from

internationally recognized standards bodies with preferential treatment given to the following standards bodies: IEEE, IETF, IEC, ISO, and the W3C • Where standards do not exist, new standards shall be

proposed and developed within these organizations “– “Clean layered architecture”

ZigBee IP Architecture Overview

November 2009


doc.: IEEE 802.15-09-0770-00

Submission

• IEEE 802.15.4-2006 with some extensions proposed in task group 4e• IETF networking standards:

– 6LowPAN (RFC 4944)– IPv6 (RFC 2460)– UDP, ICMP (probably not TCP)– ROLL (in Internet-Draft form now)

• IEC standards– 61968 CIM– Extensions from ZigBee SE and OASIS (harmonized back into the CIM)

• W3C standards– EXI (probably, though could be another tokenized XML solution)

• Missing technology we are working on in other standards groups:– Binary HTTP, SOAP over UDP or similar binary web services transport protocol

(though IETF 6LowAPP or Transport Work Group)– Embedded Service Location Protocol (SLP) (through IETF) – MAC enhancements (in IEEE 802.15 task group 4e)– Meter Access Side Communications standard (in IEEE 802.15 task group 4g)

Submission

• IETF IP networking stack (aligns with PAP 1)• PAP 3, 4, 9 and 10 align with the IEC 61968 CIM.

ZigBee SE 2.0 and OASIS will create syntax from the model

• IEEE 802.15.4 aligns with PAP 2 • NIST Phase 3 – Certification (defined at the end of

2009)– Align ZigBee Smart Energy V2 certification and

interoperability process around NIST approved certification process

ZSE 2.0-- Process Going Forward

Submission

• Simplified installation for new smart energy applications in large apartment or commercial buildings with no other control networks

• Further expansion of the Home Area Network market by enhancing the ease of use and commercial viability of Smart Energy

• Advent of PHEVs in 2010 requires energy management system to address technical and business problems related to charging/discharging, billing, and access management.

• Common system architecture and application profile interface for home energy devices independent of networking technology
