  1. Al Hefner (NIST Lead) Frances Cleveland (Technical Champion)

  2. PAP 7 Overview • Status of IEC 61850-7-420 and IEEE 1547.8 • Identify new issues for PAP 7 • Update the Scoping Document • Develop a White Paper based on Scoping Document

  3. PAP 7:Task Interactions Task 2: IEEE 1547.4 for island applications and IEEE 1547.6 for secondary networks MIC Task 4: Develop and Harmonize Object Models PAPs IEC 61850-7-420: Expanded to include Multifunctional ES-DER operational interface; Harmonized with CIM & MultiSpeak; Mapped to MMS, DNP3, web services, & SEP v2 3

  4. PAP 7 Scope - Energy Storage and Distributed Energy Resources • Develop Scoping Study on Energy Storage and Distributed Energy Resources • Complete IEEE 1547.4 and .6 • Initiate IEEE 1547.8 on electrical connectivity of ES-DER allowing low-voltage ride-through, microgrids, and other ES-DER management • Develop Use Cases for ES-DER • Develop information exchange requirements to submit to IEC TC57 WG17 • Monitor IEEE 1547.8 and IEC TC57 WG17

  5. DER (Generation and Storage) Cost Justification 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, harmonic-damping Rapid response to frequency deviations

  6. Different DER Interactions: Direct Control, Interactive Requests, Broadcast/Multicast

  7. DER Key Use Cases Must Cope with Many Different Configurations 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 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

  8. PV/Storage Inverter-based System Phase 1 Functions and Interactions Phase 1 Functions Connect/Disconnect from grid Limit maximum generation Set power factor Var settings, based on voltage Var settings, based on watts Storage charge / discharge rate (fast PEV chargers??) “Pricing” signal Event / history logging State / status reporting Time synchronization Interaction Direct command Immediate request Change settings Schedule of settings based on time Schedule of settings based on temperature Phase 2 Functions Low voltage ride-through!! Counteracting frequency deviation Other

  9. One PV/Storage Inverter Mode

  10. IEC 61850-7-420 for DER Logical Devices (LD) Logical Nodes (LN) Logical Nodes Data Objects (DO) Common Data Classes (CDC) Common Data Class Common Attributes Common Components Standard Data Types • IEC 61850 – Interface Standard of Object Models for Utility Industry • Very modular • Establishes “well-known” standardized names, data formats, and services • Initially focused on substation automation, but now being expanded • IEC 61850-7-420 for DER • Addresses only the “Nouns” • IEC 61850 object modeling constructs of LNs, etc: • Covers: • General DER management • Photovoltaic systems • Fuel cells • Diesel generation • Combined heat and power • Wind power is handled separately (IEC 61400-25) • Currently status is Final Draft International Standard (FDIS) • Due to become International Standard (IS) by mid-2008

  11. Current Status • IEEE 1547.8 has its writing groups developing the first draft of the document • IEC 61850-90-7 is being developed as a Technical Report that contains all of the proposed ES-DER additions to IEC 61850-7-420 • TR IEC 61850-90-7 will be an informative document that can (hopefully) be approved by the IEC within 6 months • With this TR, vendors can start to implement IEC 61850-7-420 even though they recognize that some minor changes might be made • In parallel, these (and other) data objects will be added to IEC 61850-7-420 Ed 2 for normative standardization within 2 years • Develop a White Paper based on Scoping Document
