The document discusses smart grids in India. It defines a smart grid as an electrical grid that uses information technology to improve efficiency and reliability of electricity production and distribution. It describes the different domains of a smart grid including bulk generation, transmission, distribution, customers, operations, markets, and service providers. The document outlines the potential benefits of smart grids such as optimizing costs, integrating more renewables, improving power quality and reliability. It then provides an overview of India's status with smart grids, including smart city projects, demand side management programs, and renewable energy integration efforts.

3. Definition by Wiki
A smart grid is an electrical grid that
uses information and communication technology to
gather and act on information, in an automated
fashion to improve the efficiency, reliability,
economics, and sustainability of the production and
distribution of electricity.

6. Distribution Domain
Distribution
Distributes the electricity
to and from the end
customers
Connects the smart
meters and all intelligent
field devices, managing
and controlling them
through a two-way
wireless or wire line
communications
network.
It may also connect to
energy storage facilities
and alternative
distributed energy
resources at the
distribution level.

7. Customer Customer Domain
The end-users of electricity
Connected to the electric
distribution network
through the smart meters.
The smart meters control
and manage the flow of
electricity to and from the
customers and provide
energy information about
energy usage and patterns.
Each customer has a
discrete domain comprised
of electricity premise and
two-way communications
networks.
A customer domain may
also generate, store and
manage the use of energy,
as well as the connectivity
with plug-in vehicles.

8. Operations Domain
Operations
Manages and controls the
electricity flow of all other
domains in the smart
grid.
It uses a two-way
communications network
to connect to substations,
customer premises
networks and other
intelligent field devices.
It provides monitoring,
reporting, controlling and
supervision status and
important process
information and
decisions.
Business intelligence
processes gather data
from the customer and
network, and provide
intelligence to support the
decision-making.

9. Markets Domain
Markets
The Markets domain operates
and coordinates all the
participants in electricity
markets within the smart
grid.
It provides the market
management, wholesaling,
retailing and trading of energy
services. The Markets domain
interfaces with all other
domains and makes sure they
are coordinated in a
competitive market
environment.
It also handles energy
information clearinghouse
operations and information
exchange with third-party
service providers.
For example, roaming billing
information for inter-utility
plug-in-vehicles falls under
this domain.

10. Service Provider Domain
Service Provider
smart grid handles all
third-party operations
among the domains.
These might include web
portals that provide
energy efficiency
management services to
end-customers, data
exchange between the
customer and the utilities
regarding energy
management, and
regarding the electricity
supplied to homes and
buildings.
It may also manage other
processes for the utilities,
such as demand response
programs, outage
management and field
services.

12. Potential Benefits
Optimizing the cost of existing production and
transmission capacity
More renewable integration
Improving power quality
Improving utility’s power reliability, load and
delivery efficiencies ,asset management and overall
production
Consumer participation
