2. WHAT IS A SMART GRID ??
 A smart grid is an electrical grid which
includes a variety of operational and energy
measures including smart meters, smart
appliances, renewable energy resources,
and energy efficiency resources.
 Electronic power conditioning and control of
the production and distribution of electricity
are important aspects of the smart grid.

3. WHAT IS A SMART GRID ??
(CONTD..)
 Adding sensing, embedded processing and
digital communication makes the grid:
a) Observable
b) Controllable
c) Automated
d) Fully Integrated
e) More efficent

5. NEED FOR A SMART GRID
 Electromechanical electrical grid are inefficient
network highly prone to power failure. It has
become a stressed grid structure.
 Energy demand is increasing at the faster rate than
energy supply because of the increase in
population.
 With the increase in energy costs, customer
expectation are also increasing.
 Greenhouse gas emission is increasing due to the
increase in energy consumption..
Clearly, a new method is required……..

6. WHAT WOULD A SMART GRID BE ABLE TO
DO THAT
TODAY’S NOT-SO-SMART GRID CAN’T ?
 Right now, if there’s a breakdown at your local
substation, the utility usually finds out when
customer call to complain. Placing a networked
sensor inside a transformer or along wires could
locate and report a problem, or prevent it from
happening in their first place.
 Despite living in the age of information, most of us
only get a glimpse of our energy consumption when
the utility bills come once a month. In people home
the smart grid should mean more detailed
information through home energy – monitoring
tools.

8. COMPONENTS OF A SMART
GRID…
The smart grid has two main components:
 The connectivity network
 Core network
 Distribution network
 Acess network
 Sensing and measurement
Core network:
The core network handles connectivity between
substations and utilities. Technology used for core network
implementation include…
 Wireless technologies
 Fiber

9. •DISTRIBUTION NETWORKS:
The distribution networks handles broadband connectivity for
transmitting data collected by Smart Power Grid concentrators and
distribution automation devices (e.g. monitors, sensors), which are
located on the grid, to their related databases and analytic servers,
which are located at headquarters.
 Sensing and Measurement:
It’s easy to cut your electricity bills if you know…
 Exactly how much electricity you are using.
 How much it is costing you in rupee per hour.
 How much harmful carbon-di-oxide your household contribute to the
environment

10. SMART METER
Smart meter are to mutual benefit for utility and
consumer.
The smart meter makes a greener difference.
 Comunication
 Smart disconnect/reconnect
 Voltage quality
 Energy awareness
 Tariffing ( reduces power demand during peak
hours)
