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
modeling
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
distribution energy resources1
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)

requirements

restful service definition
RESTFul Service Definition
  • Input
    • Using HTTP GET or POST following URL naming convention
  • Output
    • Using XSD for return
restful url naming convention
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)
restful der for a pev convention
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
