This document discusses advanced metering infrastructure (AMI). It defines AMI as a system that allows for two-way communication between utilities and smart meters, enabling near real-time collection and transfer of energy usage data. The key components of an AMI system include smart meters, communications infrastructure, home area networks, a meter data management system, and operational gateways. While costly to implement, AMI provides benefits like improved reliability, lower energy costs, and reduced electricity theft. The document also examines AMI in the context of India's power grid and estimates costs associated with deployment.

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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

3. Introduction
The present system of energy metering as well as billing in
India uses electromechanical and somewhere digital energy meter.
It consumes more time and labour. One of the prime reasons is the
traditional billing system which is very inaccurate, slow, costly, and
lack in flexibility as well as reliability.
Today accuracy in electricity billing is highly recommended.
The ‘Smart energy meter’ gives real power consumption as well as
accurate billing. It provides real time monitoring of utility of
electricity.
4. What is AMI?
AMI(Advanced Metering Infrastructure) is the
collective term to describe the whole infrastructure from
smart meter to two-way communication network to
control center equipment and all the applications that
enable the gathering and transfer of energy usage
information in near real-time.
AMI makes a two-way communications with
customers possible and is the backbone of smart grid.
5.
6. Building blocks of AMI
AMI is comprised of various hardware and software components, all
of which play a role in measuring energy consumption and transmitting
information about energy, water and gas usage to utility companies and
customers. The technological components include:
1. Smart meters
2. Wide-area communications infrastructure
3. Home(local) area networks(HAN’s)
4. Meter Data Management Systems(MDMS)
5. Operational gateways
7. Smart meters
Smart meters have the
capacity to collect information
about energy, water, and gas
usage at various intervals and
transmitting the data through
fixed communication networks
to utility, as well as receiving
information like pricing signals
from utility and conveying it to
consumer.
9. Home Area
Networks(HANs)
A Home Area
Network (HAN) interfaces
with a consumer portal to
link smart meters to
controllable electrical
devices.
10. Meter Data
Management
System (MDMS)
A MDMS is a database
with analytical tools that enable
interaction with other
information systems.
One of the functions of MDMS is
to perform validation, editing
and estimation on the AMI data
to ensure that despite
disruptions in the
communications network or at
customer premises, the data
flowing to the systems described
above is complete and accurate.
11. Operational Gateways
AMI interfaces with many system-side applications to
support:
• Advanced Distribution Operations (ADO)
• Advanced Transmission Operations (ATO)
• Advanced Asset Management (AAM)
12. Advanced Distribution Operations
• Distribution Management system with advanced sensors
• Advanced Outage Management
• Distribution automation
• Distribution Geographic Information system
• Application of AMI communications infrastructure for:
o Micro grid operations(AC and DC)
o Hi-speed information processing
o Advanced protection and control
o Advanced grid components for distribution
13. Advanced Transmission Operations
• Substation automation
• Hi-speed information processing
• Advanced protection and control
• Modeling, simulation and visualization tools
• Advanced regional operational applications
• Electricity Markets
14. Advanced Asset Management
• System operating information
• Asset “health” information
• Operations to optimize asset utilization
• Training and development planning
• Condition based maintenance
• Engineering design and construction
• Consumer service
• Work and resource management
• Modelling and simulation
15. Challenges
Despite its widespread benefits, deploying AMI presents three major
challenges that include
1. High capital costs: A full scale deployment of AMI requires expenditures on
all hardware and software components, including meters, network
infrastructure and network management software, along with cost
associated with the installation and maintenance of meters and information
technology systems.
2. Integration: AMI is a complex system of technologies that must be integrated
with utilities, information technology systems including Customer
Information Systems (CIS), Geographical Information Systems (GIS), etc.
3. Standardization: Interoperability standards need to be defined, which set
uniform requirements for AMI technology, deployment and general
operations and are the keys to successfully connecting and maintaining an
AMI based grid system.
16. Benefits of AMI
The benefits of AMI are generally categorized as:
• Operational benefits: AMI benefits the entire grid by improving the
accuracy of meter reads, energy theft detection and response to power
outages, while eliminating the need for on-site meter reading.
• Financial benefits: AMI brings financial gains to utility, water and gas
companies by reducing equipment and maintenance costs, enabling faster
restoration of electric service during outages and streamlining the billing
process.
• Customer benefits: AMI benefits electric customers by detecting meter
failures early, accommodating faster service restoration, and improving
the accuracy and flexibility of billing. Further, AMI allows for time-based
rate options that can help customers save money and manage their
energy consumption.
17.
18. Legacy system Vs AMI system
• Smart metering uses the upgraded technology for automatic,
accurate reading of energy usage.
• Once a smart meter is installed, there is no longer a need for a
representative from the energy company to come out to take a
reading. The unit uses mobile communications technology to
instantly and accurately provide energy usage directly to the
utility. This automatic process eliminates human error and
provides complete and total accuracy.
• Energy usage information is captured on a regular basis,
approximately every 30 minutes for electricity usage and once a
day for gas usage.
19.
20. AMI in the Indian context
Modernizing India's grid system by investing in AMI promises to
mitigate a number of strains placed on the grid due to growing demand.
In particular, AMI will improve three key features of India's grid system
including:
• System Reliability: AMI technology improves the distribution and overall
reliability of electricity by enabling electricity distributors to identify and
automatically respond to electric demand, which in turn minimizes power
outages.
• Energy Costs: Increased reliability and functionality and reduced power
outages and streamlined billing operations will dramatically cut costs
associated with providing and maintaining the grid, thereby significantly
lowering electricity rates.
• Electricity Theft: Power theft is a common problem in India. AMI systems
that track energy usage will help monitor power almost in real time thus
leading to increased system transparency.
21. Costs associated with AMI
Costs associated with the deployment of AMI arise from three
sources:
• Smart devices at user points.
• Installation.
• Communication network.
• Data collection, analysis, storage and system management.

24. Conclusion
Advanced Metering Infrastructure allows the operators and utility
companies to have firsthand information on the status of their network
for planning and performance optimization purposes. It also offers
higher power quality and stability.
Advanced Metering Infrastructure is a relatively new concept which
needs improvement in the areas of communication, data analysis and
control schemes. However, taking into the account the global energy
market’s situation and environmental concerns that motivates
governments, companies and consumers to fuel AMI research and
utilization, the prospect of AMI looks promising.
