Country/Economy Smart Grid Needs(Testbed
Perspective)

• Easily reconfigurable infrastructure for a
  variety of experiments
• Protocols in place to apply international
  standards
• Ability to assess components (hardware-in-the-loop
  ) and integrated systems
• Ability to work at large scale, to simulate
  real-world grid-level effects
• High level of rigor in data collection,
  calibration, and accuracy
• Multiple layers of infrastructure power systems,
  data/information processing, communications

Value of an International Collaboration

• DETL works with many industry partners interested
  in global markets
• Advances in power electronics are taking place
  across the globe access to latest in new
  developments
• Greater knowledge/understanding of standards and
  protocols from other parts of world can
  facilitate in-country development
• Development and operations of test facilities can
  benefit from knowledge of testbed innovations in
  other countries
