SMART GRID
Under the Guidance of Submitted By
Dr. Mahendra Kumar Vinay Kumar Singh
Head of Department 1404320057 (III year)
Department of Electrical Engineering Electrical Engineering
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
PRESENT ELECTRICITY GRID COMPARISON
 EXSISTING GRID
 ELECTROMECHANICAL
 ONE -WAY
COMMUNICATION
 CENTRALIZED
GENERATION
 FEW SENSORS
 MANUAL MONITORING
 MANUAL RESTORATION
 FAILURES AND
BLACKOUTS
 LIMITED CONTROL
 SMART GRID
 DIGITAL
 TWO-WAY
COMMUNICATION
 DISTRIBUTED
GENERATION
 SENSORS THROUGHOUT
 SELF MONITORING
 SELF HEALING
 ADAPTIVE AND
ISLANDING
 PERSASIVE CONTROL
The Grid as it’s stands
What’s at Risk
 National Economy
 Security
 Environment/climate changes
 Global competitiveness
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

ENERGY CONSERVATION
TECHNIQUES IN TRANSFORMER
 IMPROVEMENT IN DESIGN AND MATERIAL OF
TRANSFORMER
 By using energy efficient transformer.
 By using amorphous transformer
ENERGY CONSERVATION DURING
TRANSMISSION
 BY REDUCING RESISTANCE
 BY CONTROLLING VOLTAGE LEVELS
BY REDUCING RESISTANCE
BY CONTROLLING VOLTAGE LEVELS
ENERGY CONSERVATION DURING
DISTRIBUTION
 BALANCING OF PHASE LOADS
 POWER FACTOR IMPROVEMENTS
WER FACTOR IMPROVEMENT
Advanced Transmission System
 Phasor measurement units
 Wide area monitoring systems
 Flexible AC transmission system
 SCADA
 FLISR
 Power electronics
 Islanding concept
Advanced Distribution System
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.
FLEXIBLE AC TRANSMISSION SYSTEM
 Voltage control
 System stability
 Controls real and reactive power flow
 High speed response
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.

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
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
CHALLENGES
 Lack of awareness
 Security
 Opposition and concerns
 High Investment / Cost Factor
 Meters can easily be hacked
 Utilities can increase/decrease demand of power
INDIA’S ELECTRICITY NEEDS
 DEMAND – 2,10,000 MW
 (CENTRAL ENERGY AUTHORITY MOP)
 PRODUCTION- 1,82,000 MW
 INSTALLED CAPACITY - 2,25,000 MW
 DEFICIT- 10.2%
