2- Outline of the Talk
- Historical Perspective Problem Statement
- Smart Grid Systems of the Future
- Research
3Selected Energy Statistics by Country (1998) Sourc
e International Energy Agency
4- World average energy production per capita (ê)
grew significantly from 1920 to its all-time peak
in 1979. - Then from its peak in 1979 to 1999, then it
declined at an average rate of 0.33 /year.
5Energy Sustainability Discussion
Primary Energy All We Use Comes from the Sun.
Energy sustainability requires use of resources
at the same rate at which they are naturally
replenished on earth without externalities.

Earth at night - 2007
7Energy Sustainability Discussion
Earth at night 2030
8Production of CO2 Since 1700
9Energy Sustainability Discussion
- Proven Energy Resources around the world
Reserves-to-production (R/P) R/P ratios
represent the length of time that those remaining
reserves would last if production were to
continue at the previous year's rate. It is
calculated by dividing remaining reserves at the
end of the year by the production in that
year. BP website www.bp.com
10Global Climate
- Departures in temperatures ( degree celsius )
from 1961-1990 average

11The Future?As for me, all I know is that I know
nothing. SocratesLet Us Speculate
12Speculate for Possible Solution
- We need to change the rate of growth of Co2
- We need to control the exponential growth Co2 ,
level it and then reduce it . We need to develop
a sustainable modern industrial society. How? - Efficiency. Every Energy user---an energy
producer - Everyone must have a skin in the game.

- Distributed Generation Systems (DG)

planned deployments, and proposals by
investor-owned utilities and some public power
utilities. http//www.edisonfoundation.net/IEE.
As of this writing, approximately over sixty
million customers have been equipped with a
smart meter.

18Smart Grid Load Management Techniques
- Peak Clipping Peak clipping method seeks to
reduce - the peak load demand
and match it - with the power
companies available - power generation

19Smart Grid Load Management Techniques
- Valley Filling This method is based on
scheduling - certain load during the
time of the day - when the load demand is
low due - to consumer life style
