Vision and Strategy for India’s Electricity Metering Infrastructure of the fu...IJERA Editor
In the country like India with over millions of kilometers of transmission lines and billions of consumers, task of
collecting information related to energy consumption of every consumer is a critical job. The meter reader has to
travel a long distance and take reading manually to collect the data. This reading is then feed in a central
database. Then the bill gets generated later with help of software. This project intends to reduce this tedious
work by automating the process of collecting data from consumer’s electricity meter. This would be done by
implementing Advanced Metering Infrastructure that unites all the various metering devices of a building in one
network and provides the metering data in real-time, locally and from remote. Here, AMI uses ZigBee to build
up high-rise building area network of connected metering devices.

Vision and Strategy for India’s Electricity Metering Infrastructure of the fu...IJERA Editor
In the country like India with over millions of kilometers of transmission lines and billions of consumers, task of
collecting information related to energy consumption of every consumer is a critical job. The meter reader has to
travel a long distance and take reading manually to collect the data. This reading is then feed in a central
database. Then the bill gets generated later with help of software. This project intends to reduce this tedious
work by automating the process of collecting data from consumer’s electricity meter. This would be done by
implementing Advanced Metering Infrastructure that unites all the various metering devices of a building in one
network and provides the metering data in real-time, locally and from remote. Here, AMI uses ZigBee to build
up high-rise building area network of connected metering devices.

A Comprehensive Review of Artificial Neural Network Techniques Used for Smart...ssuser793b4e
The recent developments in computational science and smart metering have led to a gradual replacement of the traditional load forecasting methods by artificial intelligent (AI) technology. The smart meters for residential buildings have become available on the market, and since then, various studies on load forecasting have been published. Contingency planning, load shedding, management strategies and commercialization strategies are all influenced by load forecasts. Predicting a lower load than the actual load results in utilities not committing the necessary generation units and therefore incurring higher costs due to the use of peak power plants; on the other hand, predicting a higher load than actual will result in higher costs because unnecessary baseline units are stated and not used . Artificial Neural Networks (ANNs) provide an accurate approach to the problem of energy forecasting and have the advantage of not requiring the user to have a clear, understanding of the underlying mathematical relationship between input and output. The aim of this work is to a carry-out Comprehensive Review of Artificial Neural Network Techniques Used for Smart Meter-Embedded forecasting System.

One promising means of reducing the transmission and distribution losses is through the distributed generation of electricity closer to the end user such as net metering schemes. And the other approach is managing customer consumption of electricity in response to supply conditions, for example, stimulating electricity customers to reduce their consumption at critical times or in response to market prices, thereby reducing the peak demand for electricity. In order to assist consumers to make informed decisions on how to manage and control their electricity consumption, consumers should have a system to monitor their real-time electricity consumption as well as a communication network with the service provider. But traditional electricity meters only record energy consumption progressively over time, normally in monthly basis and provide no information of when the energy was consumed. Therefore the necessity of Advanced Metering Infrastructure (AMI) has been emerged to address the above matters. Nowadays most of the nations are looking to rollout into Smart Meters enabling faster automated communication of information to consumers on their real time electricity consumption, and to service providers.
a smart meter electronically measures how much energy is being used and how much it costs, and then communicates it to the energy supplier and the customer. Smart meters can also enable the provision of new services to consumers as it can record consumption of electric energy in intervals of an hour or less, and also gather data for remote reporting using two-way communication between the meter and central system.

1. INTRODUCTION
Energy savings nowadays is very important aspect. This requires intelligent distribution, monitoring and
management of energy. A solution of this problem is advance meter reading (AMR) which means to collect data
from different kind of meter. In this way we can measure usage of water, gas and energy can be remotely
monitored. This is in differing with the manual meter reading which is actually based on people we have
employed to collect the data from the meters. That is having lots of disadvantage and error of prone thus the get
into modern buildings may be limited for security reasons; to collect data from meters from homes, different
apartments, buildings that require a lot of time and usual data is collected once a month or once in a two months
which may be a too small resolution. Automatic meter reading is the technology of automatically collecting
consumption, analysis, and status datafrom water meter or energy meter devices like gas devices, electric devices
and transferring that information to a server for billing process, problem solving, and examining it. This
technology mainly saves providers the cost of periodic trips to each physical location to read a meter data.
Another benefit is that billing made by the utility that would be from real time consumption so accuracy will be
maintained. This timely information coupled with analysis can help both utility providers and customers for
better control the use and production of electric energy, AMR technologies include mobile and network
technologies based on telephony platforms, radio frequency (RF), or power line, transmission. So we should have
particular infrastructure for such problems andthat would be advanced metering infrastructure (AMI).

2. REVIEW OF RESEARCH PAPERS
2.1 PAPER – 1 Cloud-based smart metering system (IEEE 2013, Authors: Peter Dukan, Attila Kovari)

consumers. This application is cloud based web application on the server side. Cloud based energy management
solutions require standardized communication between smart meter and server. For that we are using M-bus
standard which provides us local communication and we are using gateways and data collectors to send
information to web server through internet. The highly safe storage of such amount of data and large availability
of service for users can be ensured by computing power and data storage capability of cloud technology. In the
cloud based solution users are served by information technology services available on the web. These services
divided on the servers of service providers and operational details are hidden from users. Cloud based solution
provides cost effective service to the millions of users. We are using Saas(software as a application) to serve the
need of enquiries generated by user and function of Saas to provide transferring information and display the
consumption to user.
2.2 PAPER – 2 A Data Collection Algorithm Using Energy Maps in Sensor Networks (IEEE 2007,
Authors: Abdelmorhit EL RHAZI, Samuel PIERRE)
This paper gives brief information about new data collection mechanism based on distributing cluster methods
which uses energy maps and apply the Qos requirements to reduce consumption. Energy map gives visual
presentation of how energy and material flows through the process and also gives information about different
network area‟s consumption using energy maps. This algorithm uses data aggregation and second is filtering
methods. These both methods are used to minimize the transmitted messages over a network and its used to
reduce power consumption and increase the network coverage. Foe data collection algorithm two methods are
used data aggregation and data filtering to collect the information and to filter the network messages
simultaneously. In this paper comparison between data collection algorithm and TAG (tiny aggregation)
algorithm is shown. TAG algorithm is all about generic aggregation service for networks. It processes aggregates
into the networks by computing data as flows through the sensors and it discarding the irrelevant data and collect
relevant data. It is the rooting algorithm means, all the packets communicated from sink node to all network
nodes. And if we got any queries than as a solution we can use language similar to SQL (structured query
language). TAG algorithm is having two phases distribution phase and collection phase. In distribution phase
queries pushed down from sink node to single node and in the collection phase aggregate values are rooted up
continuously from child node to parent node. This algorithm uses clustering building method in which nodes are
split into the set of clusters and that will satisfy application requirements and also reduce the energy consumption
and increase the network life.
2.3 PAPER – 3 ,Utilities Look to the Skies for Monitoring the Power Grid (IEEE 2004,Published by IEEE
computer society)
In this paper the power utilities looking to the skies to help them to collect meter information about electricity
usage. Actually they are using satellites to acquire the data on the real time basis so that accuracy could be
maintained. This system is developed by hunt power which also providing metering equipment and services to
the most power utilities. In this phenomenon a network of 25 satellites are there and it will be in the low earth
orbit used to collect data from meters at any location. A particular time duration is fixed for collection of data
and in this approach the time duration is about 15 minutes and it is also having ability to query the meters in the 6
minutes. Each satellite is linked with the smart meter unit having size of 8*8*8 inch box with external whip
antenna. It is having 148-150 MHz UHF transceiver capable of two way communication with satellite. It is
designed in such a way that it will be fit into existing metering installations. The communication occurred
serially, wireless and wired. And it queries the collection unit on demand and converting the usage information
into transmittable form. It provides two levels of password protection. Data collected by satellite from diverse
subscribers is then sent on a periodic basis from every 15 minutes in real time to gateway earth station and then
to the gateway control centre where messages are stored , processed, sorted ,and rerouted.
2.4 PAPER – 4 A genetic algorithm based power consumption scheduling in smart grid buildings (IEEE
2014, Authors: Eunji lee, HyokyungBahn)
As we see the recent advancement in the smart grid technology and increasing dissemination of smart meters
electricity usage can be detected at any moment and send them to the utility office for further process. Nowadays
utility office adopting different prices at different time. This paper gives brief information about new power

consumption scheduling algorithm for smart buildings which adopts smart meters and real time pricing of
electricity. Normally the prices are high at peak hours for example in the afternoon on hot days in the summer.
Consumer can detect the price change through smart meters and reduce electricity usage when the prices are low
and increase usage when prices are high. To achieve all economic benefit of dynamic pricing it is imperative that
electric devices equipped with automatic price aware scheduling mechanism requires so that minimum action
came from the consumers. For this smart socket have been developed and placed between appliance and
electricity outlet, and monitors electricity usage information of appliance and it is also having ability to
communicate with smart meters and control electrical state of appliance. In this algorithm standardized
communication protocols for smart appliance are developed and it also establishes HAN (home area network)
whose function is to perform communication with smart meters and controlling remotely.
2.5 PAPER – 5 Efficient Data Collection for Smart Grid Using Wireless Sensor Networks(IEEE
2013,Authors: Kwangsoo Kim, Hyochan Bang, Seong-il Jin)
The focus of this paper is on central data collection quickly and without collisions. As a solution we divide a tree
in which network constructs several branches and each meter having its own data collection path unit to leaf
meter. The novel method used to avoid the collisions between query and query responses and in between query
responses. Nowadays wireless sensor networks begun to use in the smart grids including advance meter reading
(AMR) and advance metering infrastructure (AMI), here AMI and AMR are used to achieve the load balancing.
It roughly consists of centralized server, smart meters and DCU (data collection unit). A server manages lots of
DCU‟s and a DCU manages hundreds of smart meters. In this system WSN (wireless sensor network) used in
between smart meter and DCU. A DCU in a smart meter is similar to sink node in a sensor network and smart
meter acts as a sensor node. DCU‟s periodically collect power consumption and status data from all meters in the
system within the time interval and transmit the data to server. After collecting metering values it will create
dynamic price for consumers than calculate cost according to the consumption of electricity usage than to settle
on the basic charge for exchanging power at power exchange and after that calculate total power consumption.
One drawback is that while collecting electricity usage if some data is lost than billing process will not
completed accurately and even if usage utility will show more consumption than complaint can be occurred. So
as a solution conventional DCU‟s are developed by electric utilities which will be collect data without collisions.
3. Data acquisition
It is the process of measuring electrical or physical phenomenon such as voltage, current, temperature, and pressure
with the computer. It consists of data acquisition measurement hardware current sensor, computer with
programmable software. The aim is to measure of quantity, the data and that will be stored in the cloud. The user
will be able to access his account also able to know his consumption.
Fig 1 Data acquisition flow
3.1 Current sensor
For the data acquisition we have to use acs712 current sensor of 5 ampere. Actually it is a device which detects
electric current (ac or dc) and generates signal proportional to it and this current sensor gives analogue output so we
have to use analogue to digital converter. And for that we need mcp3008 ic which is analogue to digital conversion
integrated chip to the raspberry pi. This enables raspberry pi to interpret analogue voltages that is emitted by
analogue based sensor and then reflect the measure of any physical characteristic.

4 Advance metering infrastructure (AMI)
Advanced metering infrastructure (AMI) is the integrated system of smart meters, communications networks,
data management systems which enables two way communications between utility and consumer. Advanced
Metering Infrastructure (AMI) are systems which measure data, collect data, analyse energy usage information,
and communicate with meters like as electricity meters, gas meters and water meters on request. These systems
include hardware, software, communications, energy displays and controllers, customer associated systems,
meter data management (MDMS) software. Government agencies and utilities are turning toward advanced
metering infrastructure (AMI) systems as they are part of larger Smart Grid initiatives. Advance metering
infrastructure extends current advanced meter reading technology with giving two ways meter communications,
and commands to be sent toward the home for multiple purposes, including time-of-use pricing, demand-
response actions. The network between the measurement devices and business systems allows collection of data
and distribution of information to customers, suppliers, utility companies. This allows these businesses to
findings contribute in demand response services. Customers can use information submitted by the system to
change their normal consumption patterns to take benefit of less prices. AMI differs from traditional advance
meter reading (AMR) in that it enables two-way communications with the meter.
