15. Enhanced ZigBee Smart Energy
November 2009
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 on the NIST list for the Smart Grid
Robert F. Heile, ZigBee Alliance

16. November 2009
Why a ZigBee IP stack?
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 – with MAC security
6lowPAN packet format and fragmentation
ROLL routing
Plus other features essential to effective sensor networks
Robert F. Heile, ZigBee Alliance 16

17. Smart Energy 2.0 and ZigBee IP Background
November 2009
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 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
Robert F. Heile, ZigBee Alliance 17

18. ZigBee IP Architecture Overview
November 2009
ZigBee IP Architecture Overview
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”
Robert F. Heile, ZigBee Alliance 18

19. ZigBee IP Standards Selection
November 2009
IEEE 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 task group 4e)
Meter Access Side Communications standard (in IEEE task group 4g)

ZigBee Smart Energy 2.0 Development Plan
MAC/PHY
IEEE
HomePlug AV/SE
Interoperate with any other MAC/PHY (WiFi, Ethernet, etc.)
Networking
IETF standards
Application
Aligned with IEC CIM
Message syntax defined through XML
Robert F. Heile, ZigBee Alliance 20

21. ZSE 2.0-- Process Going Forward
November 2009
ZSE Process Going Forward
IETF IP networking stack (aligns with PAP 1)
PAP 3, 4, 9 and 10 align with the IEC CIM. ZigBee SE 2.0 and OASIS will create syntax from the model
IEEE 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
Robert F. Heile, ZigBee Alliance 21

22. Why ZigBee+Power Line Carrier?
November 2009
Why ZigBee+Power Line Carrier?
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
