Background


Trend of energy production and consumption in
United States
(Source: Energy Information
Administration, Energy Perspectives, Figure 1
(June 2009))










Result in power outage and frequent blackout, e.g., 5 massive
blackout in past 40 years, 3 in past 9 years

Background (contd.)


Current power network is broadcast network
and heavily depends on centralized power plants
and power distribution infrastructures


Environmental concerns, such as green gas emission
and expanding power infrastructure annoying
community


Vulnerable to single point failure and expensive to
recover after a weather or earthquake disaster


Smart Grid
: integrate renewable energy sources,
allow distributed power generation and supply,
reduce peak load thus dependence on power
plants


Many research problems to study and solve

Motivation


Foster Smart Grid research ecosystem by
inventing lab
-
based smart grid testbed


Allow experiments to test and compare different
designs in lab environment


Dimensions for innovation:


seamless integration of renewable energy sources


management of intermittent power supplies


real
