3. INTRODUCTION
ADVANCED METERING INFRASTRUCTURE
 AMI is not a single technology, but rather an integration of
many technologies that provides an intelligent connection
between consumers and system operators
 AMI provides an essential link between the grid, consumers
and their loads, and generation and storage resources.
 Smart meter
 Home area networks
 Meter data management system

4. Smart meter
Conventional electromechanical meters served as the utility cash
register for most of its history.
 Smart meters are solid state programmable devices that
perform many more functions, including most or all of the
following:
 Time-based pricing
 Net metering
 Loss of power (and restoration) notification
 Remote turn ON / turn OFF operations
 Load limiting for “bad pay” or demand response purposes

6. SMART METER :Communication Media
 The AMI communication infrastructure supports continuous
interaction between the utility, the consumer and the
controllable electrical load.
Various media can be used for communication
Power Line Carrier (PLC)
Broadband over power lines (BPL)
Copper or optical fiber
Wireless, either centralized or a distributed mesh
Internet

7. Types of smart meter
 There are two basic categories of Smart Meter
 Radio frequency
Mesh Technology : Group of Smart Meters talks to a collector
Point to point Technology: Each Smart Meter directly talks to a collector(Tower)
 Power line carrier
 Data and information is transmitted via utility power lines.
Latest Smart Meters uses a Hybrid design or combination design for improved
performance.

9. Functions of smart meter
 Time-based pricing
Net metering
Loss of power (and restoration) notification
Remote turn ON / turn OFF operations
Load limiting for “bad pay” or demand response
purposes

10. Benefits of smart meter
 Consumer benefits : It also means higher reliability, better
power quality, more prompt and more accurate billing.
 Utility benefits : AMI helps the utility avoid estimated
readings, provide accurate and timely bills, operate more
efficiently and reliably and offer significantly better consumer
service
 Social benefits :One way is through improved efficiency in
energy delivery and use, producing a favourable
environmental impact.

11. VULNERABILITIES
 Fabricating generated energy meter readings
 Manipulating energy costs
 Sending false control signals
 Disabling grid control center computer systems
and monitors
 Disabling protective relays.

12. VULNERABILITIES
AMI introduces serious privacy concerns, as
immense amounts of energy use information will be
stored at the meter. Breaches into this data could
expose customer habits and behaviours.
In order to defend against the vulnerabilities
described above, several security features need to
be incorporated into the development of AMI, to
protect consumers.

13. FUTURE SCOPE
 Smart meters have been introduced as a means
to modernise the grids and to bring about
operational changes such as reduce nontechnical
losses, introduce remote reading and switching or
simplify the billing procedures.

14. CONCLUSION
 The existing grid is not intelligent and is operated near its thermal
limits due to increasing population and power demand.
 Advanced Metering Infrastructure is a relatively new concept which
needs improvement in the areas of communication, data analysis and
control schemes.
 A smart meter is a green meter because it enables the demand
response that can lead to emissions and carbon reductions.
It facilitates greater energy efficiency since information feedback is
shown to the consumers to reduce usage.
 AMI allows the users to better control their consumption pattern. It
also offers higher power quality and stability.
