3. INTRODUCTION
Smart grid is a combination of hardware management and
reporting software in order to built a intelligent
communication infrastructure.
Integrates Information and communication technology (ICT)
to the power system for :-
Increased reliability
More security
Better efficiency
Reduced environmental impacts

6. WORKING OF SMART GRID
Integration of all sources of energy mainly renewable
Continuous monitoring and feedback from network
Helps in fault prevention
Establish a two way communication
Reduces the stress on existing infrastructure
Reduces and shifts the peak demand
Conserve energy during transmission and distribution
Uses better technologies
7. ENERGY CONSERVATION
TECHNIQUES IN TRANSFORMER
IMPROVEMENT IN DESIGN AND MATERIAL OF
TRANSFORMER
By using energy efficient transformer.
By using amorphous transformer
8. ENERGY CONSERVATION DURING
TRANSMISSION
BY REDUCING RESISTANCE
BY CONTROLLING VOLTAGE LEVELS

SCADA
FLISR
Power electronics
Islanding concept
ADVANCED DISTRIBUTION SYSTEM
10. PHASOR MEASUREMENT UNIT
It’s (PMU) a device which measures the electrical waves on
an electricity grid using a common time source for
synchronization.
Works on the concept of synchro phasor technique.
11. FLEXIBLE AC TRANSMISSION SYSTEM
Voltage control
System stability
Controls real and reactive power flow
High speed response
12. INTRODUCTION TO SCADA
Supervisory control and data acquisition (SCADA)
The SCADA system in the control room is able to make these
automated decisions in real-time by running algorithms based
on the data it receives and adjustments to optimize voltages
and self-heal any disruption issues.
13. SMART METERS
Uses a secure national communication network (called the
DCC) to automatically and wirelessly send your actual energy
usage to your supplier
More accurate bills
Better understanding of your usage
Innovative energy tariffs
14. ADVANTAGES
Reduces carbon foot prints
Increased capacity to fulfil demand
Improves distribution management
Self healing capability
Automated control for distribution
Increased efficiency
Sustainability
New types of loads such as EVs
15. CHALLENGES
Lack of awareness
Security
Opposition and concerns
High Investment / Cost Factor
Meters can easily be hacked
Utilities can increase/decrease demand of power
18. CONCLUSION
It would go on a long way in solving present energy issues.
Has positive environmental impact
Has long term economic outcome
Drawbacks in short term like lack of funding
Problems of privacy
Lack of public support initially
