1 Innovative Smart Grid Technologies Conference Enterprise Integration Implications of Home-Area Networking Technologies Gary A. McNaughton, P.E. and Robert Saint, P.E. January 21,

2 Potential Smart Grid Customer Interaction Innovative customer responses enabled by emerging smart grid include: Response to innovative rates critical peak pricing, real time pricing, etc. Ability to respond to critical peak alerts Ability to respond to availability of renewable generation or carbon-management signals Ability to offer ancillary services DG, DS, PHEV 2

5 Introduction to MultiSpeak Developed by NRECA in collaboration with key industry vendors, originally to serve small utilities with limited IT staff and no messaging infrastructure Covers applications of interest to distribution utilities Standard is mature, but scope is continuing to grow In use at over 500 utilities, in at least 11 countries Mature interoperability testing program, applies to all interfaces Semantic model originally implemented using XML; currently developing UML model under PAP08 Service definitions implemented in web services; batch transport profiles also defined More information is available at 5

6 GWAC Stack Context for MultiSpeak 6

7 MultiSpeak Architecture 7

8 MultiSpeak Specification Semantic framework documented in XML schema moving to UML model. Rich set of service definitions, documented in web services (WSDL). Web service payloads formatted in XML. Supports both request/response and pub/sub. Uses GML to exchange geographical constructs. Easy to extend for semi-custom implementations. Currently most implementations are in Version 3.0. Version 4.0 issued in February 2009 Well defined, third-party interoperability testing program. 8

9 MultiSpeak Background MultiSpeak Initiative is a group of over 50 vendors that provide products and services to distribution utilities. Utilities interested in supporting the effort are encouraged to join. Currently about 30 utilities are members of MultiSpeak, including Consumers Energy and DTE. Members have access to latest drafts of specification and can affect the direction of the spec. 9

11 HAN Requirements that Imply Enterprise Information Flow Acceptance of utility-directed control actions Action based on price signals Display of utility-generated messages and alerts Monitoring, measurement and reporting of DG, DS, PHEV, etc. Commissioning and provisioning of HANs and HAN devices Security key exchange 11

12 Abstract Enterprise Capabilities Necessary to Realize HAN Requirements Price Management Message Management Demand Management Demand Response Management Commissioning and Provisioning HAN Communications 12

13 Price Management Abstract Capability Functions Prepare price signals Prepare schedules of price applicability Output Pricing signal appropriate for display in customer premises display 13

14 Message Management Abstract Capability Functions Prepare message content Prepare schedules of message display Output Message content appropriate for display in customer premises display 14

15 Demand Management Abstract Capability Functions Determines when load control is appropriate Establishes target for load shedding Output Load control signal appropriate for communication with Demand Response abstract function. 15

16 Demand Response Management Abstract Capability Functions Accepts signal from Demand Management Manages customer load so as to meet demand targets Output Load control signal appropriate for communication with customer premises EMS Returns Feedback from customer EMS on outcome of control actions (Success/Failure/Customer bypass) Returns composite feedback to Demand Management 16

17 Commissioning and Provisioning Abstract Capability Functions Coordinates commissioning and provisioning of customer premises networks and HAN devices Exchanges security keys to establish secure communications Output Commissioning, provisioning and security key exchange messages for communication with customer premises portal. 17

18 HAN Communications Abstract Capability Functions Manages exchange of output from Price Management, Demand Response Management, Message Management, and Commissioning/Provisioning. Output Messages and signals appropriate for communications with customer premises portal. 18
