This document discusses smart grids and the role of advanced metering infrastructure in India. It notes that India has one of the weakest electrical grids in the world with high transmission losses. A smart grid uses communication and information technologies to better manage electricity distribution and demand. Advanced metering infrastructure is a key component, allowing two-way communication between utilities and customers to provide energy usage data and enable demand response programs. This can help improve grid reliability and efficiency while empowering consumers.

2.  Smart
Grid is the modernization of the electricity
delivery system so that it monitors, protects and
automatically optimizes the operation of its
interconnected elements.
 Smart grid is the integration of information and
communications system into electric
transmission and distribution networks.
 The flow of electricity from utility to consumer
becomes a two-way conversation i.e. two way
flow of information.

3.  India
is having one of the weakest
electrical grids in the world
 10 to 20 % of power is lost to THEFT
across the utilities in India.
 15-20% power transmitted is lost in the
transmission and distribution network
 Huge commercial losses due to poor
billing, metering, collection at depth etc

4. Proactive
management of electrical
network during emergency situations.
Better demand supply / demand
response management.
Better power quality
Reduce carbon emissions.
Increasing demand for energy : requires
more complex and critical solution with
better energy management

6. Self-healing: The grid rapidly
detects, analyses, responds, and restores
 Empowers and incorporates the consumer
 Tolerant of attack: The grid mitigates and is
resilient to physical/cyber-attacks
 Provides power quality needed by 21st-century
users: The grid provides quality power consistent
with consumer and industry needs
 Accommodates a wide variety of supply and
demand.
 Fully enables and is supported by dynamic

Smart Metering –
 Automatic, Time of Use, Consumer Communication & Load Control

Communications : Automated Metering
Infrastructure (AMI) – LAN, WAN, HAN

DRMS (Demand Response Management)

In Home enabling technology
o Demand in three category:
• Immediate, Deferrable, Storable
o Customer aggregation & De-aggregation required for Peak shifting

10.  Enhance
power system measurements
and enable the transformation of data into
information.
 Evaluate the health of equipment, the
integrity of the grid, and support advanced
protective relaying.
 Enable consumer choice and demand
response, and help relieve congestion

11.  Advanced
Metering
Infrastructure (AMI)
o Provide interface between the
utility ad its customers: bi-direction
control
o Advanced functionality
• Real-time electricity pricing
• Accurate load characterization
• Outage detection/restoration

12.  Health
Monitor:
Phasor measurement
unit (PMU)
o Measure the electrical
waves and determine
the health of the
system.
o Increase the reliability
by detecting faults
early, allowing for
isolation of operative
system, and the
prevention of power
outages.

13. The Key to Effective Demand Side Management

14.  AMI
is a basic element of the smart grid; its role
is to furnish information and active interactive
capability to service providers and customers
 AMI consists of smart meters, integrated two
way communications infrastructure, active
customer
interface,
and
meter
data
management system to gather and store
customer data
 In addition, AMI provides interfaces to other
electricity company enterprise systems

16.  The
smart meter is the central nervous system
of the AMI
 The ability to collect consumption data in
discrete time intervals allows the utilities to
charge time differentiated rates for electricity
usage
 The meter can also perform other useful
advanced functions, such as remote
connect/disconnect
 The meter is also a key need in the

17. 
Direct Load Management:
 Direct Load Control
 Interruptible tariff
 Demand Bidding

Indirect Load Management:
 Pricing programs
 Rebates
 Education programs

The financial status of power sector can be effectively
improved by demand side management

20. Changes
in electric usage by end-use
customers in response to changes in
the price of electricity over time is
expected to produce major changes
from normal consumption patterns.
This will help the utilities in
undertaking effective management of
power distribution.
