2 Topics IEC in a Nutshell IEC UML Model IEC mapping to SEP 2.0 Bottom-Up Approach to CIM/61850 interactions IEC WG17 DER, Storage, and PEV Activities WG14 RBAC Response to WG15 Questionnaire

3 IEC in a Nutshell IEC UML Model IEC mapping to SEP 2.0 Xanthus Consulting International

4 Nutshell Description of IEC Nouns Logical Devices (LDs): Informative only, and consist of groups of LNs Implemented using System Configuration Language (SCL) Logical Nodes (LNs): Normative, consisting of Data Objects Used for organizational and naming purposes Data Objects: Data elements within LNs Common Data Classes: Format of Data Objects Value, quality code, timestamp Common Attributes Quality codes, enumerations Hi-Lo range limits Standard Data Types Floating point, binary, integers Logical Devices (LD) Logical Nodes (LN) Data Objects (DO) Common Common Data Classes Data Class (CDC) Common Components Attributes Standard Data Types

5 Nutshell Description of IEC Verbs Get data object Value, quality, timestamp, as defined in CDC Put data object Controls, settings, etc. Get metadata (self-discovery) Logical nodes and data objects Establish datasets Sets of data with criteria for reporting on data changes Get dataset (all data objects in a dataset in order) Put dataset (all data objects in a dataset in order) Report-by-exception of datasets Reported when one or more values change beyond a deadband Periodic integrity scan Logging of events with timestamps System Configuration Language (SCL) tools are used to configure implementations

6 Logical Devices Contain Logical Nodes, Constructed of Data Objects, Structured by CDCs, and Mapped to Protocols (such as MMS, DNP3, Web Services, or SEP) LN XCBR DOs showing CDCs Controller containing Logical Device Communication Protocols Messaging Services Data Set Management Device Applications Proprietary Database Logical Device Logical Nodes LN XCBR LN CSWI LN LN CPOW SIMG LN MMXU1 Status Data Objects CBOpCap : INS CB operating capability Measured Value Objects SumSwARs : BCR switched amps Control Data Objects Pos : DPC switch position BlkOpn : SPC block opening Setpoint Control Objects Connections to Physical Device LN MMXU2

7 WG10 Effort: UML Diagrams of IEC CDCs, Data Sets, and Logical Nodes Being Developed by Tanja Kostic Common Data Classes Logical Nodes

8 Proposed SEP UML for IEC CDCs Does not include all optional data elements (Readable example of MV & SPS)

9 Possible SEP Verbs for IEC Get/Put Data Objects provides monitoring, controlling, and setting values of individual data elements Get/Put Datasets provides monitoring, controlling, and setting values of groups of data objects that were established at implementation time or later. Data set values are reported automatically when values change or on a periodic basis. Logging: Not quite sure on collecting and transmitting logs (Robby??) Report-by-Exception: Still working on the exact mechanism to provide report-by-exception (Robby may be able to explain more).

10 Bottom-Up Approach: IEC CDCs Mapped to CIM Complex Datatypes Xanthus Consulting International

13 Bottom-Up Approach IEC has about 39 CDCs that define format or structure of the Data Objects Some elements of CDCs are mandatory while others are optional Some elements of CDCs are very commonly used, while others are not Some CDCs are very commonly used, while others are not For the cross-over between measurements coming from field devices using to MeasurementValue in the CIM: Select key CDCs Select mandatory elements in those CDCs Develop complex datatypes for each key CDC in CIM Accept (don t model in CIM) all Data Objects, using the appropriate CDC complex datatypes

14 IEC WG17 DER, Storage, and PEV Activities Xanthus Consulting International

15 DER (Generation and Storage) Functions and Interactions DERs will provide: Energy (real power) from generators and from storage units Reactive power support (volt/var support) to both distribution and transmission efficiency and stability Combined generation and storage can provide rapid response to mitigate intermittent renewable resources like wind and solar Low voltage ride-through, emergency reserves, harmonicdamping Rapid response to frequency deviations DER will be managed: By customers for their own exclusive use Through direct control by utilities or aggregators Through market-driven bids, with direct control by utilities Through market-driven, tariff-based demand response

16 Different DER Interactions: Direct Control, Interactive Requests, Broadcast/Multicast DER Energy Management System at Utility Site or Customer Site Loosely-coupled Two-way Interactive Requests Controller DER Integrated System DER Generator Utility/ESP DER Management System One-way Broadcast/ Multicast Loosely-coupled Two-way Interactive Requests Tightly-coupled Direct Control Controller DER Storage Loosely-coupled Two-way Interactive Requests Tightly-coupled Direct Control Distributed Energy Resources (DER) Site DER Management: Interactions between Components

17 DER Key Use Cases Must Cope with Many Different Configurations Direct, tightly-coupled control Between inverter controller and ES-DER device Between Customer EMS and multiple ES-DER devices in a building, subdivision, or campus Interactive two-way monitoring and control Between ISO/RTO and ES-DER system whose bid has been accepted Between Customer EMS and multiple ES-DER systems with their own (sophisticated) controllers Broadcast/multicast one-way pricing or request signals Between utility and Customer EMS Between aggregator and ES-DER systems

23 WG15 Response WG15 is having a meeting Oct in Knoxville We will review the WG14 submission Already have some questions: Can you identify which roles might be Mandatory and which Optional or are they all Optional?
