  1. Mark Ortiz Enterprise Architecture & Standards

  2. CIM Data Requirements Overview • Based on SEP 2.0 TRD • Included previous SEP data requirements, NASBE, and others such as SAE • Covers the following messages: • Common • Demand Response & Load Control • Directed & Public Messages • Pricing • Pre-payment • Metering and Sub-metering (OpenSG) • PEV • DER • Billing

  3. Modeling • Based on IEC CIM model & 61850, 61968, 61970 (such as Part-9metering and control) • New models (classes/attributes/relationships) based on SEP2.0 TRD for DER & PEV

  4. Distribution Energy Resources

  5. Distribution Energy Resources • Mainly three new classes involved: • DistributedEnergySource is a node for a DistributedGeneratingUnit from network perspective. It just likes a ServiceDeliveryPoint links to a MeterAsset. DistributedEnergySource has a relationship to EndDeviceAsset just like SDP has a relationship to EndDeviceAsset so that metering can be established for a DistributedEnergySource/DistributedGeneratingUnit. • DistributedEnergySource (DES) could be associated with HANAsset (Now PANDeviceAsset) if it is in a HAN environment. • DES could be associated with a Battery (or name changed to EnergyStorage). • PowerGenerationCurve is associated with DistributedGeneratingUnit for energy output (measurement)

  6. Example on how SEP 2.0 UML aligns with CIM UML • SEP 2.0 Pricing Data Model New attribute (href) To identify a RESTful resource New class to meet SEP 2.0 TRD requirements

  7. Example on how SEP 2.0 UML aligns with CIM UML • CIM Pricing Structure Model

  8. RESTFul Service Definition • Input • Using HTTP GET or POST following URL naming convention • Output • Using XSD for return

  9. RESTFul URL Naming Convention • <Service Namespace>/<root element>/<child element> such as • http://www.zigbee.org/datastore/MeterReading/Readings  (for all readings) or • http://www.zigbee.org/datastore/MeterReading/Readings/?timeStamp=2010-02-02T00:00:00Z  (for readings with the timestamp)

  10. RESTFul DER for a PEV Convention • GET /dgu{#} returns the DGU for a PEV The client would send: GET /dgu/0 HTTP/1.1 Host: {IPv6 Address} The server would respond: HTTP/1.1 200 OK Content-Type: application/xml Content-Encoding: exi <?xml version=’1.0’ encoding=’UTF-8’?> <DistributedGeneratingUnithref=”http{s}://{IPv6 Address}/dgu/0”> <ID>001</ID> </DistributedGeneratingUnit> <DistributedGeneratingUnithref=”http{s}://{IPv6 Address}/dgu/1”> <ID>002</ID> </DistributedGeneratingUnit>
