8 Outline What is the Smart Grid HAN? (Bigger Picture) (Some) Key Initiatives HAN Standards and Technologies Potential Products and Applications Q&A 8

9 What is the Smart Grid HAN? (Bigger Picture)

10 System Architecture 10

11 Residential vs. Commercial and Industrial (C&I) Original focus has been on residential HAN Some debate on need for two protocols or one Transactive pricing and energy use often discussed for C&I Focus on protocols inside the HAN vs. to the HAN C&I already has some established technologies: BACnet LonWorks 11

12 (Some) Key Initiatives

13 Open Standards Now no longer largely debated, but has been in the past Many benefits, including: Multiple sources/suppliers Ease of integration (including internal) Prevents vendor lock-in Lessens local variation 13

14 Internet Protocol (IP) Technology that led to the explosion of the Internet Largely debated in the past in AMI, substation automation, and HAN Many benefits, including: Internetworking mixing various MAC/PHY technologies Availability of COS products Vast labor pool Advantage of hard-won wisdom (particularly in security) of Internet community Eases convergence 14

15 IP in the HAN PLC WiFi ZigBee IP Ethernet HomePlug 15

16 IEC Common Information Model (CIM) Common dictionary for Smart Grid semantics IEC / IEC TC57 Many benefits, including: Common model across smart grid Decoupled from underlying technologies allows flexibility for future technology changes Eases convergence 16

17 HAN Standards and Technologies

4 Traditionally a turn-key solution, also providing: ZigBee Stack (ZigBee PRO, ZigBee IP, ) meshing is hard

18 ZigBee Wireless Mesh Low power (gas meter, battery-powered thermostats) Low cost Lower speed (~150 kbps) IEEE Traditionally a turn-key solution, also providing: ZigBee Stack (ZigBee PRO, ZigBee IP, ) meshing is hard Application Layer Profile (SEP 1.x, HA, ) Supported by ZigBee Alliance, with ~400 members and many vendors in all levels of the supply chain Large utility support, with approximately 40 million meters under contract 18

11 technologies (a, b, g, n) Traditionally solely focused on MAC/PHY, running typical protocols and applications (such as IP and HTTP)

19 Wi-Fi Wireless Star Medium to high energy use Appears to still be more costly than ZigBee, especially given the economies of scale Higher speeds (10 54 Mbps) Suite of IEEE technologies (a, b, g, n) Traditionally solely focused on MAC/PHY, running typical protocols and applications (such as IP and HTTP) Supported by Wi-Fi Alliance, with ~400 members and many vendors in all levels of the supply chain Enormous adoption in the consumer electronics space Some utility interest, though no meter support to my knowledge, for instance 19

20 HomePlug Powerline Communication Variety of technologies: HomePlug AV Higher cost Higher speed (~200 Mbps) IEEE 1901 HomePlug Green PHY Lower cost Lower to medium speed (~10 Mbps) Subset (and interoperable with) IEEE 1901 Traditionally solely focused on MAC/PHY, running typical protocols and applications (such as IP and HTTP) Supported by HomePlug Alliance, with ~60 members and many vendors in all levels of the supply chain Some adoption in the consumer electronics space Some utility interest, some meter deployment, interest in MDU issue Great interest from auto manufacturers for plug-in electric vehicles 20

21 Smart Energy Profile Application-layer profile a collection of standards where options and configurations are specified (for instance, prepayment support) with the intention of leading to interoperability and managing embedded device constraints Focus on communications related to efficiency, usage, price communication, demand response and load control, and messaging Range of backhaul (AMI, Internet, etc.) bandwidths and cost kept in mind during development Developing with several organizations including: ZigBee Alliance HomePlug Powerline Alliance Wi-Fi Alliance EPRI SunSpec Alliance SAE IETF UCAIug 40+ million meters with ZigBee and/or HomePlug currently under contract, from a variety of the major North American and international meter manufacturers Robust testing and certification program with logoing 21

22 Smart Energy Profile versions 1.0 (Publicly Released June 2008) Certified Products available today Designed only for ZigBee stack Support for Price Communication, Demand Response and Load Control, Messaging, and Metering (as well as security and basic information such as time) 1.1 (Publicly Released July 2011) Incremental enhancements to 1.0 including Prepayment and Billing Information For support of existing deployments and pilots *** Development on 1.x may continue after 2.0 is released *** 2.0 (In Development, Subject to Change) Wireless and Wired (Link Layer Agnostic) Designed for IP stack, RESTful HTTP Harmonization with IEC (CIM) and Continuing to add new features (PEV support, MDU support, etc.) 22

23 SEP 2.0 Key Documents and Dates Within ZigBee, specifications are not considered to be complete until there are Certified Products Market Requirements Document (MRD) - COMPLETE Technical Requirements Document (TRD) - COMPLETE 0.7 version of Application Specification (Interop-Ready) COMPLETE Interop Testing / Gating Begins - ~7 months 0.9 version of Application Specification (Certification-Ready) 30 days Certification Testing - ~2 months Final Specification (Certified Products) Done! 23

24 SEP 2.0 Current Status SEP 2.0 Application Specification (App Spec): Last ballot received ~4000 comments Several face-to-face meetings (typically once per month) Several interoperability events (typically once per month) Most, if not all, contentious items thought to be resolved CSEP established Joint testing and certification organization between HomePlug, Wi- Fi, ZigBee, and others 24

25 OpenADR C&I Application Still in early stages Little industry support (but growing) Original support primarily in California, LBNL, and Honeywell Focused on transactive energy use OpenADR 1.0 from LBNL OpenADR Alliance formed to create OpenADR 2.0 very recently 25

26 Green Button Batch Download Still in early stages, but moving quickly Based on NAESB ESPI standard White House initiative Provides access to bulk energy usage information In process of developing testing and certification plans Supported by new SGIP PAP 26

27 Potential Products and Applications

28 Device Types (from SEP 2.0) ESI (Energy Services Interface) can be integrated into utility meter (often the case) or standalone In-Premises Display PCT (Programmable Communicating Thermostat) Load Control Devices (Pool Pumps, Water Heaters, Appliances, Lighting, etc.) Plug-In Vehicles Inverters Dumb devices (Refrigerator Magnet, Glowing Orb, etc.) 28

29 (Some) Function Sets (from SEP 2.0) Pricing Communication Demand Response and Load Control Metering / Energy Usage Information Messaging Pre-Payment Confirmation Plug-In Electric Vehicles Distributed Energy Resources Billing Registration Firmware Download Basic, Time, Commissioning, Power Configuration, etc. 29

35 Security Application layer security built around TLS May also have link layer security Think https Certificates Have agreed on a specific ECC cipher suite as the mandatory cipher suite for interoperability Have agreed on a specific RSA cipher suite as an optional cipher suite for interoperability 35

36 Application Transport HTTP the web protocol we all know and love Used to interact with resources in a RESTful manner 4 verbs: GET, PUT, POST, DELETE Driven by desire to have a long-lived protocol and a familiar protocol for consumer interactions 36

37 Name Resolution mdns Multicast DNS Familiar to many via Apple Bonjour Enable DNS names without the need for a centralized DNS server Used in conjunction with DNS-SD to provide device and service discovery 37

38 Device and Service Discovery DNS-SD, used in conjunction with mdns Service Discovery Types and Sub-Types Essentially just DNS TXT records Give me all smartenergy devices Give me all smartenergy metering devices Returns various information such as path 38

39 Application Payload Format Message format of the HTTP resources Still TBD, but likely EXI Efficient XML Interchange Tokenized XML W3C standard 39
