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
connection/disconnection
of components

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

Connection configuration in IPS:
 multiple supplier - single consumer
 single supplier - multiple consumer
 parallel connection

IPS hardware:
 Ports connect to: power supply/ appliance/ energy
storage/ another IPS
 TelosW controller, shift registers
 Solid state relays S116S01

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
