This document presents information on advanced metering infrastructure (AMI) and smart meters. It discusses AMI as an integration of technologies that provides communication between utilities and consumers. Smart meters are described as solid state devices that perform functions like time-based pricing and remote operations. The document outlines different types of smart meters and their communication media like power line carrier and wireless. It also discusses the working principle, functions and benefits of smart meters, as well as potential vulnerabilities and future applications.

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.
