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.

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?

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.

Traditional power grid & future smart grid

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

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.

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.

Present Scenario of Indian Energy
System

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

Priority areas to build smart grid
technology (Identified by NIST)
 Demand Response and Consumer Energy Efficiency.
 Energy Storage.
 Electric Transportation.
 Advanced Metering Infrastructure.
 Distribution Grid Management.
 Cyber Security.
 Network Communications.

Renewable Energy sources (2014)

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