Distributed 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
DRGS DEWG Initial Topics
1) International DER Interconnection Standard
2) 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 functions
4) Grid supportive functions at Microgrid/EMS area Point-of-Connection

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 testing
7) Regulatory/market issues for distributed, variable/constrained
