ABSTRACTǾ 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 TODAYUtilities 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

FEATURESThe 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.
13
SMART SUBSTATIONSCENARIO:
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
SMART HOUSESCENARIO:
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

INVESTMENT
Approximately $60 to $100 million
Cost is offset by joint funding from
partners and contributions of:
Utility hardware
IT hardware
Software
Labor resources

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.
