March 13-14, 2014 | NIST Campus | Gaithersburg, Maryland Dedicated Smart Grid Testbeds (SG TBs) are being developed by industry, academia, and government laboratories to characterize smart grid equipment and systems and validate smart grid performance and standards. At this nascent stage, much needs to be done to develop shared understanding of needs, opportunities, and approaches for integrating testbed design and operation to achieve the full potential of the evolving smart gird.
