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

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 ESDER 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
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, harmonicdamping
• Rapid response to frequency deviations
Different DER Interactions: Direct Control,
Interactive Requests, Broadcast/Multicast
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
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
One PV/Storage Inverter Mode
IEC 61850-7-420 for DER
• 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”

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
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
