The document discusses the concept of the smart grid, a power system that allows for two-way communication between the grid and connected devices, emphasizing improvements in energy efficiency and the integration of renewable energy sources. It compares traditional and smart grids, noting the benefits of reduced carbon footprints, enhanced customer participation, and improved management of energy resources. The document also addresses challenges such as the complexity of the network, potential security issues, and high installation costs.

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 Smart Grid.

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. 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 to two days).
Why do we need smart grid?

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

6. Traditional power grid & future smart grid

7. Comparison
Existing Grid Smart Grid
 One-way communication Two-way communication
 Centralized generation Distributed generation
 Few sensors Sensors throughout
 Manual monitoring Self-monitoring
 Manual restoration Self-healing
 Few customer choices Many customer choices

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

9. Electric Transportation
Plug In Hybrid Electric Vehicles
 Capable of both generating and storing electricity through
gasoline engine and battery.
 Can be recharged at night during low cost periods.
 Efficient means of transportation.
 Reduces oil consumption.
 Reduces pollution.

10. Present Scenario of Indian Energy
System

11. AT&C LOSS
Varies between 20% to 45%
Average in between 30 to 35%
