New DRGS DEWG
SmartThe
GridDistributed Renewables, Generators, Storage
• DRGS DEWG initiated September 2011• Identify Smart Grid standards and interoperability issues/gaps for
– Integration of renewable/clean and distributed generators and storage– Operation in high penetration scenarios, weak grids, microgrids, DC grids– Including interaction of high-bandwidth and high-inertia type devices
• Of particular importance are Smart Grid functions that – mitigate impact of variability and intermittency of renewable generators – enable generators and storage to provide valuable grid supportive services – prevent unintentional islanding and cascading events for clustered devices
• Activities of new group– Consistent approaches for generators/storage types and domains– Use cases and information exchange requirements– Define new PAPs to address standards gaps and issues
• Join: http://collaborate.nist.gov/twiki-sggrid/bin/view/SmartGrid/DRGS
SmartThe
GridDRGS DEWG Initial Topics
1) International DER Interconnection Standard2) Consistent object models for different generator and storage device types,
different domains and constraints – in different standards, international 3) Process for continued development of advanced grid supportive generator
and storage functions4) Grid supportive functions at Microgrid/EMS area Point-of-Connection
– Premises Local EMS with no ability to remote disconnect– Microgrid with EMS and ability to disconnect/reconnect from Area EPS – Power electronic flow controller interconnected Microgrids– Power electronic converter interconnected DC Microgrids/DC circuits
5) Information exchange requirements for operation of DER in scenarios– Management of DER by Distribution System, Microgrid, or Premises EMS– Autonomous interaction of DER with IEDs (breakers, switches) and/or other DER– High penetration and weak grid conditions
6) Conformity and interoperability testing7) Regulatory/market issues for distributed, variable/constrained

Subgroups to further define issues, gaps and action plans:A. DRGS Standards Roadmap B. DRGS Use Cases, Information Exchange, and Object Models C. DRGS Microgrids and Hierarchical Distributed Control D. DRGS Conformity and Interoperability Test and Certification E. DRGS Regulatory and Market Issues
Meetings format/schedule: – Subgroups meet and report out as sessions during bi-weekly webinar– Alternate weeks used for additional subgroup meetings
Timeline and Deliverables: – Subgroup descriptions, leaders, and participants - February– Descriptions of issues and DRGS actions for priority action items - March– Roadmap for DRGS DEWG to address issues and gaps - April
