2012 Washington, DC
Sandia is a multiprogram laboratory operated by
Sandia Corporation, a Lockheed Martin Company,
for the United States Department of Energys
National Nuclear Security Administration under
contract DE-AC04-94AL85000. SAND2009-2801P
2Country/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
3DETL A Reconfigurable Smart-Grid Testbed
- Scenarios
- Grid-connected and off-grid
- Controllable loads simulate residential,
commercial - Multiple sources
- Energy storage
- Home/building/network EMS
- Optimization of new DG/DER components and systems
- RD and product development
- Pre-commercial testing and characterization
- Protocol and standards development
- Demonstration

14Value 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
