What is Smart Grid/Metering for electric
distribution? Should they be implemented in the
US?

• Presented by Jeffrey Grodzki, April Romanishan,
  Cameron Hinkel, and Emily Grady

2
What is Smart Grid?

• Advanced technology aimed at increasing the
  efficiency of the countrys aging electricity
  infrastructure and accommodating emerging energy
  sources.
• Makes it easier for electricity distributors to
  gather and act on information, such as
  information about the behaviors of suppliers and
  consumers.

Smart Grid Contd...

• A smarter grid applies the three Ts to bring
  knowledge to power
• Technologies
• Tools
• Techniques
• They apply knowledge capable of making the grid
  work far more efficiently by
• Ensuring its reliability to degrees never before
  possible
• Maintaining its affordability
• Reinforcing our global competitiveness
• Fully accommodating our renewable and traditional
  energy sources
• Potentially reducing our carbon footprint

Smart Grid Contd

• Transforming our nation's grid has been compared
  in significance with building the interstate
  highway, or the development of the internet.
• These efforts, which are rightly regarded as
  revolutionary, were preceded by countless
  evolutionary steps. Much like a highway is built
  or how the internet came to be today, the Smart
  Grid will evolve over time.

Smart Grid Contd

• Power System Fact
• Todays electricity os 99.97 reliable, yet still
  allows for power outages and interruptions that
  cost Americans at least 150 billion each year.
  Which is about 500 for every man, woman, and
  child.

Viewpoint 1 Benefits for implementing Smart
Grid in the US

• More efficient transmission of electricity
• Quicker restoration of electricity after power
  disturbances
• Reduced operations and management costs for
  utilities, and ultimately lower power costs for
  consumers
• Reduced peak demand, which will also help lower
  electricity rates
• Increased integration of large-scale renewable
  energy systems
• Better integration of customer-owner power
  generation systems, including renewable energy
  systems
• Improved security

Smart Grid technologies in other countries

• Chinas smart grid is about
• 10,000 meters now but by 2020
• they plan for it to about 300 million
• meters.
• If the test phase is successful,
• SGCC (Smart Grid Corporation of
• China) will cover about 80 of the
• country.

Self-Healing Grid

• A self-healing grid includes these primary
  functions
• Real-time monitoring and reaction, which allows
  the system to constantly tune itself to an
  optimal state
• Anticipation, which enables the system to
  automatically look for problems that could
  trigger larger disturbances
• Rapid isolation, which allows the system to
  isolate parts of the network that experience
  failure from the rest of the system to avoid the
  spread of disruption and enables a more rapid
  restoration.

Consumer benefits of Self-Healing Smart Grid

• Beyond, managing power disturbances, a smart grid
  system has the ability to measure how and when
  consumers use the most power. This information
  allows utility providers to charge consumers
  variable rates for energy based upon supply and
  demand.
• Ultimately, this variable rate will incentivize
  consumers to shift their heavy use of electricity
  to times of the day when demand is low and will
  contribute to a healthier environment by helping
  consumers better manage and more efficiently use
  energy.

ViewPoint 2 Drawbacks of Implementing the Smart
Grid in the US

• Security
• Cyber-security threats
• Theft
• Power loss
• Computer malware

12
Cont.

• Costs
• There is a huge initial investment cost for the
  utility company
• Energy prices rise for consumers (variable
  pricing)
• Heavy government support through grants and
  stimulus packages

13
Still Cont.

• Cultural Lag
• Consumer adoption to these smart grid
  technologies takes years
• Will consumers truly use this data in their homes
  and take advantage of it?
• Consumers may not benefit as much as the utility
  companies who are pushing smart technologies

14
Conclusion

• While both the benefits and drawbacks are
  significant, both sides seem to balance out the
  other
• For example Security problems might rise from
  this smart technology, Smart grids when used and
  implemented PROPERLY can save everyone time,
  money, and at the same time benefit the
  environment.

15
Conclusion Cont.

• Another stalemate between positive and negative
  is that despite the threat of possible cyber
  attacks a self healing grid can attempt to
  anticipate things going wrong, isolate the
  problem, and solve it before it gets out of hand.

16
Cont.

• So all in all, in the end with kinks ironed out,
  the smart grid could be a viable solution for
  issues related to both consumers and producers.
