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:

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

Common::TimeSchedule
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 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)

RESTFul Service Definition
• Input

Using HTTP GET or POST following URL naming convention
• Output

Using XSD for return
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
• 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’?>
<DistributedGeneratingUnit href=”http{s}://{IPv6 Address}/dgu/0”>

</DistributedGeneratingUnit>
<DistributedGeneratingUnit href=”http{s}://{IPv6 Address}/dgu/1”>
