 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.

 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

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

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

 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

 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

 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.

The Key to Effective Demand Side Management

 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

 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



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

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.

 Energy Usage Information
 Efficient Communication between Utilities and

Customers
 Consumer Enrollment in DR programs
 In Home Technology- Availability & Purchase

, Device Provisioning
