INTRODUCTION
• Simply means a “ Smarter “ Power Grid.
• A Smarter grid with improved efficiency and two way
communication.
• Reducing carbon emissions as it is integrated with renewable
energy resources.
• A Network created through IT , communication technology and
Electrical Power system.
• Can handle digital , computerized equipment and technology
dependent on it and can automate and manage the increasing
complexity and needs of electricity.

SMART HOME
Inside Smart home new equipment, appliances, and software are
available that use emerging Smart Grid technologies to save energy,
seek out the lowest rates, and contribute to the smooth and efficient
functioning of our electric grid.

INTEGRATION OF RENEWABLE ENERGY

It will give grid operators new tools to reduce power demand quickly when wind or solar
power dips.
It will have more energy storage capabilities to absorb excess wind and solar power when it
isn't needed, then to release that energy when the wind and solar power dips.
Energy storage will help to smooth out the variability in wind and solar resources, making
them easier to use.
Building an electric superhighway can also help solve the problem, as it will help to ship the
power to where it is needed.

GRID OPERATION CENTRES
9
Primary task of grid is to
Make sure that as much
power is generated as is
being used.
Otherwise grid can
become unstable.
Grid operators also have
limited information about
how the power is flowing
through the grid.
Smart Grid technologies offer a
new solution to the problem of
monitoring and controlling the
grid's transmission System.
Reducing the need to fire up
costly secondary Plants.
Grid operators can see and
manage electricity
consumption in real time.
Software could potentially
monitor the grid in real time
for potential disturbances
that could lead to blackouts.
Ex. Phasor measurement
units

PLUG-IN ELECTRICVEHICLES
• For the Smart Grid, plug-in electric vehicles represent a broader technology
known as energy storage
• PEVs can drastically reduce our dependence on oil, and they emit no air
pollutants when running in all-electric modes. However, they do rely on power
plants to charge their batteries, and conventional fossil-fueled power plants emit
pollution.
• PEVs may play an important part in balancing the energy on the grid by serving as
distributed sources of stored energy, a concept called "vehicle to grid”.

SMART GRID COMPONENTS
Smart meters
Phasor measurement
Information transfers
Distributed generation

11
SMART METERS
• Recognizes and details Electrical consumption.
• Relays information to central monitoring station.
• Will replace traditional meters.
• Time of day charges.
• Information sharing.

12
PHASOR MEASUREMENT
Measure AC current waveforms
Monitors power Quality
Wide Area Measurement system
- Provides real-time data
- Phasor data Concentrators
- Supervisory Control And Data Acquisition system
Sends information to central control station for
better management

13
DISTRIBUTED GENERATION
Allow the connection of small scale
renewable generation
-Solar ,Wind, Fuel Cells , Microturbines
Generation close to the load, improving
Efficiency
Customer Interaction
Increase Reliablity

Gujarat to get country’s first
smart grid
Times of India
 Like cell-phone users, people may be able to pick a plan for
electricity consumption. The Uttar Gujarat Vij Company Ltd (UGVCL)
will roll out India's first modernized electrical grid, or the smart grid,
in Naroda and Deesa in north Gujarat .
The pilot project will study consumer behavior of electricity usage
and propose a tariff structure based on usage and load on the
power utility. Eventually, it will be rolled out across the state to
disincentivize power consumption during peak hours.
New meters embedded with SIM cards will be installed in 20,000
residential and industrial units in Naroda to monitor data every 15
minutes on how a particular consumer uses power.

SMART GRID BENEFITS
Efficiency
Distributed Generation
Smart metering
Energy Management Systems
Reliability
Wide Area Monitoring
Environment
Renewable generation
Reduce Demand on Centralized Generation
facilities

17
DRAWBACKS
 Security and Privacy
 Some types of meters can be hacked, these hackers:
 Gain control of thousand, even millions of meters
 Increase or decrease demand of power
 Large no. of components
 Various technology components:
 e.g. Softwares, integrators etc.
 Concern that complex rate systems(e.g. variable
rates) remove clarity and accountability, allowing the
supplier to take advantage of customer
