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-time demand response
energy pricing strategy

SmartGridLab testbed Design
Power Network + Information Network
Power Network: control energy flow
Intelligent Power Switch (IPS)
Energy supplier: main supply and renewable energy source
(solar panel and small wind turbine)
Energy demander (e.g. appliances)
Information Network: sense and control power
network
Network of power meter and controller

SmartGridLab: Power Network
Intelligent Power Switch
(IPS)
Cloud of IPS
Scalable addition of new
components
No centralized control
IPS can also act like
micro-grid
Dynamic

SmartGridLab: Power Network (contd.)
IPS design: distributed and
scalable structure, with
intelligent control of
interconnections
Allows parallel connections
Switches and ports
For Np ports needed
switches:
Ns = Np.(Np - 1) / 2

SmartGridLab: Information Network
Two way communication for information
exchange and control
Possible medium: copper wiring/ optical fiber/ power
line carrier/ wireless etc.
SmartGridLab: 802.15.4 wireless network (configured
as a wireless mesh network), as low-power 802.15.4
is more flexible in a testbed environment
Allow centralized or distributed network formation and
control
