AMI SMART METER

Communication INFRASTRUCTURE TYPES OF SMART METERS WORKING PRINCIPLE OF SMART METER FUNCTIONS & BENEFICTS VULNERABILITIES CONCLUSION & FUTURE SCOPE

INTRODUCTIONADVANCED 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

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

Smart meter & Electromechanical energy meter

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

Types of smart meter

There are two basic categories of Smart Meter

Radio frequencyMesh 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.

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.

VULNERABILITIES Fabricating generated energy meter readings Manipulating energy costs Sending false control signals Disabling grid control center computer systems and monitors

Disabling protective relays.

VULNERABILITIESAMI 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.

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.

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.
