2. TOPICS
 What is smart grid?
 Conventional Power System.
 Comparison between smart grid and conventional.
 Importance of Smart Grid.
 Electric Transportation.
 Present Scenario of Indian Energy System.
 Disadvantages of SmartGrid.

3. What Is Smart Grid?
 It is a power system architecture that permits two way communication
between the grid and essentially all devices that connect to it.
 Under smart grid model , traditional generation still has a large role, but it
is augmented by distributed generation in the form of wind , solar and
various other customer- owned generation sources that not only generate
electricity for end customers, but can also sell electricity back to utility.

4. Why do we Smart Grid?
 Today's electrical grid suffers from a number of problems,
including :
Polluted (More than half of our electricity is generated
from coal).
Less efficient (The delivered efficiency of electricity is only 35%).
Vulnerable (The 2003 blackout in the Northeast affected 55M people for
up totwo days).

5. Conventional Power System
 Cannot fully support the integration of renewableenergy.
 Major source is fossil fuel.
 System is not much efficient.
 Almost zero customer participation.

6. Comparison
 Existing Grid
 One-way communication
 Centralized generation
 Few sensors
 Manual monitoring
 Manual restoration
 Few customer choices
 Smart Grid
 Two-way communication
 Distributed generation
 Sensors throughout entire
syatem.
 Self-monitoring
 Self-healing
 Many customer choices

7. Importance of Smart Grid
 Proper management of energy.
 Reduce peak demand
 Improving energy efficiency.
 Renewable energy sources.
 Reduce carbon foot prints.
 Reduce electricity bill.
 No blackouts.
 Consumers can earn money.

8. Electric Transportation
Plug In Hybrid ElectricVehicles
• Capable of both generating and storing
electricity through gasoline engine
and battery.
Can be recharged at night during low
costperiods.
• Efficient means of transportation.
• Reduces oil consumption.
• Reduces pollution.

10. AT & C LOSS
 Varies between 20% to 45%
 Average in between 30 to 35%

11. Disadvantages of Smart Grid
 Network is not simple.
 Smart meters can be hacked.
 Installation is expensive.
