What is Smart Grid?


A DoE initiative that takes advantage of modern technologies to address
the growing and changing needs of customers.



SmartGrids integrate communications networks with the power grid in
order to create an electricity
-
communications superhighway capable of
monitoring its own health at all times, alerting officials immediately when
problems arise and automatically taking corrective.



Modern Technologies:


Advanced Sensors


Communication


Advanced Control Devices



Results:


Distribute electricity more effectively all the way from transmission to
customer appliances.



Advanced Components


Improved Interfaces/Decision
Support

What is Smart Grid?


Three Key Areas



Applications


Communication


Devices

What is Smart Grid?


Modern Smart Grids should:


Detect and address
potential

problems


Acquire inputs from measurements over a rapid communication
network to diagnose problems and quickly restore network
stability.


Automatically adapt protective systems to changing network
configuration


Re
-
route power flows, change load patterns, improve voltage,
and correct network in a matter of seconds


Enable distributed resources to participate in operations


Improve reliability and security


Provide advanced visualization tools to manage network


Why Smart Grid?


Consider some of the economic consequences of power
losses:


Power interruptions and disturbances cost the U.S. electricity consumer
at least $79 billion per year


A recent rolling blackout caused an estimated $75 million in losses in
Silicon Valley alone.


When the Chicago Board of Trade lost power for an hour during the
summer of 2000, trades worth $20 trillion could not be executed.



Our nation is increasingly held back by an outdated
power delivery infrastructure.


The U.S. grid faces shortcomings in capacity, reliability, security and
power quality. Designed in the 1960s or much earlier, much of this
critical national asset is well beyond its design life.

Characteristics of SmartGrid


Self
-
Healing


Real
-
time self assessments to detect, analyze, respond, restore
grid components.


Minimize interruption time


Identification of problematic devices


Communication with local/remote devices to analyze faults, low
voltage, poor power quality, overloads, and other negative
conditions.


Customer Demand Motivation


Provide real
-
time information to consumers (cost/value)


Demand Response (DR) to shift peak demand


Real
-
time pricing


Characteristics of SmartGrid


Resists Attack


Minimizes consequences of attack


Security protocols will include; deterrence, prevention, detection,
response, and mitigation.


Technologies include; authentication, encryption, intrusion
detection, and filtering of alarms & communication.


Optimization of Assets Usage


Network will work only as much as needed.


Quality and capacity will be monitored in real
-
time.


Equipment failure rates and maintenance cost reduced.


Integrated mapping, alarming, event & crew management

and “Proactive” Delivery Management

Future Smart Grid?


What will the Future Look Like?



“SmartGrid means you fill up your car with hydrogen but
cannot drive it the next day, because your teenage
daughter has sold the hydrogen as electricity at peak
tariff over the internet, and used the proceeds to charge
her mobile phone card.”
