3. ABSTRACT
Ǿ The development and implementation of a smart grid for power
supply is one of the pressing issues in modern energy economy,
given high national priority and massive investments, although
the entire subject is still in its infancy stage.
Ǿ The smart grid delivers electricity from producers to consumers
using two-way digital technology, and allows control of
appliances in the consumers' houses and of machines in factories
to save energy, while reducing costs and increasing reliability and
transparency.
Ǿ In principle, the smart grid is an upgrade of the common
electricity grids that operate mostly to provide one-way power
from several major power plants to a large number of Consumers.
Ǿ The smart grid could be at the city level, integrate into a national
grid, or at the plant level, integrated into the urban grid ready for
the future.

THE GRID TODAY
Utilities committed to proving safe,
reliable power.
Must provide quality service with an aging
infrastructure.
Supplying energy in a carbon constrained
world.
Working with non-integrated systems
and processes.
SMART TECHNOLOGIES CAN PROVIDE
SOLUTIONS TO MODERN GRID
CHALLENGES.

NECESSITY OF SMART GRID
Grid reliability
Aging assets, heightened load
Environment:
Global climate concerns
State mandates for green power
Energy Security:
Homeland security
Dependence on foreign oil
Customer Choices:
Growing needs and expectations
Desire for greater flexibility and options
8. 8
FEATURES
The Smart Grid will:
Be more reliable.
Be self-healing and self-monitoring.
Be more secure.
Be cleaner and greener.
Support widespread distributed
generation.
Help customers better control energy use
in their homes and businesses.
Achieve lower throughput, thus lowering
prices.

ENERGY STORAGE
Scenario:
Wind, solar energy can be
stored in a battery for use
when needed.
Consumers can use wind power when
they want—not just when the wind is
blowing.
Energy storage devices can be tapped
whenever demand is high.

SMART SUBSTATION
SCENARIO:
Digital intelligence gives substation
operators remote control of facilities.
Allows faster adjustments to
conditions.
Prevents blackouts, makes for faster
recovery.
More flexibility to re-route power.
Monitors help keep facilities and sites
secure.

SMART DISTRIBUTION
ASSETS
SCENARIO:
A smart meter detects an isolated
outage in a residential neighborhood.
The utility pings the meter and is able to send
the right crew, with the right tools, to the right
location to turn power back on quickly, OR
Can remotely re-connect power
Faster restoration time and fewer outage
minutes
16. 16
SMART HOUSE
SCENARIO:
Home appliances contain onboard
intelligence that receives signals
from power grid control systems
and can reduce demand when the
grid is under stress.
Consumers automatically pre-program
appliances to turn on when prices are
lower.
Creates options for managing bills and
energy consumption habits

CONCLUSION
It won’t happen all at once:
Smart Grid will be an evolution with long-term
implications.
Start up costs involved; but savings expected
in the long run.
Solid focus will remain on Government’s
response rather than customer choice.
