INTRODUCTION:
 Electric grid delivers power from
the plants where it is generated to
consumers through transmission
and distribution lines, substation,
transforms and switches without
giving any information about
usage.
 Smart grid is the 21st century
electric grid which helps to
manage power, communicate
with consumer and use
renewable sources

WHAT IS A SMART GRID?
 Smart grid is integration of
electrical, digital,
communication, and IT
technology
 It is an intelligent future
electricity system which
delivers electricity to
consumers using two way
transmission technology.

TWO WAY COMMUNICATIONS:
 Helps in communication between
smart meter and central system
 With the help of two way
communication people can
generate their own power from
renewable sources and send energy
back to the grid that can enhance
our supply particularly during peak
hours. Hence minimizing
dependence on fossil fuels
 Two way communication helps
charging of electric cars only when
sufficient renewable energy is
present

COMPONENTS OF SMART GRID:
 A Smart grid has two main components:
1)The connectivity Network
 Core Networks
 Distribution Networks
2) Access Networks
 Sensing and measurement

CORE NETWORK:
 The Core network handles connectivity between substations
and utilities’ head offices.
 Technologies used for core network implementation include:
 Wire line technologies
 Fiber
 Wireless technologies
 WiMAX

DISTRIBUTION NETWORK:
 The Distribution network 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
analytics servers, which are located at headquarters.
 Technologies used are:
 Wireline technologies
 Fiber
 BPL (broadband over power lines)
 Wireless technologies
 WiMAX
 License-exempt broadband wireless
 GSM

SENSING AND MEASUREMENT:
 For sensing and measurement
smart meter is used
 Exactly how much electricity
you are using.
 How much it is costing you in
rupee per hour
 How much harmful carbon
dioxide your household
contributes to the greenhouse
effect

FEATURES:
 Communication-able to communicate with the data management
system which is placed on a server either at the utility or at the
system provider.
 Smart disconnect/reconnect-allows the utility to switch off the
power remotely and to switch the power back on.
 Tamper Protection- is integrated as a real time clock will stamp
any breaking of the seal.
 Voltage Quality- are measured and recorded providing the energy
distributor with valuable information to perform an efficient grid
operation.
 Load profile- The Utility may also take advantage of the recorded
load profile data and four quadrant measuring for optimization of
the grid load.
 Shunt measuring principle-secures an accurate measuring of
consumed energy.
 Tariffing- reduces power demand during peak hours
 Energy Awareness- It makes it a lot easier for the consumer to
follow his energy consumption.

ADVANTAGES:
 Reduce carbon foot-prints
 Self-healing
 Automated control for distribution
 Sensing and measurement
technologies
 increased efficiency
 Self monitoring

LOOPHOLES OF SMART GRID:
 Present Infrastructure is inadequate
and requires augmentation to support
the growth of Smart Grids.
 Most renewable resources are
intermittent and can not be relied on
(in its present form)for secure energy
supply
 Regulatory Policies to deal with
consequences of Smart Grid; like off
peak, peak tariffs and other related
matters.
 Grid Operation : Monitoring &
control

 It refers to the modernized
version of the earlier
traditional method of
energy supply.
 Smart home, smart meter,
smart city- overall, a smart
system is going to be the
reality in recent future.
