HISTORY
Grid is a term used for an electricity network which
may support all or some of the following four distinct
operations.
1. Electricity generation
2. Electric power transmission
3. Electricity distribution
4. Electricity control.
History of smart grid.
Technological improvements of the power
system largely rose in the 50s and 60s.
Nuclear power, computer controls helped fine
tune the grid’s effectiveness and operability.
With today’s technology such as wireless
protocol, network infrastructure the power grid
becomes smart grid, capable of recording,
analyzing and reacting to transmission data,
allowing for efficient management of resources,
and cost-effective appliances for consumers.
History of smart grid.
1980s, Automatic meter reading was used

FUNCTIONS
Funtions of Smart Grid
Self-healing
Using real-time information from
embedded sensors and automated
controls to anticipate, detect, and
respond to system problems, a smart
grid can automatically avoid or mitigate
power outages, power quality problems,
and service disruptions
Consumer participation
This takes shape in two forms – electricity
production and electricity consumption. One
of the many benefits of the Smart Grid is its
ability to integrate renewable energy sources
into large scale electricity production.
Another is the ability to communicate in real
time on a broad scale to signal requests to
modify electricity consumption. Both of
these benefits have profound, positive
impacts for consumers.
Resist attack / Electricity Theft.
Smart grid technologies better identify
and respond to man-made or natural
disruptions. Real-time information
enables grid operators to isolate
affected areas and redirect power flows
around damaged facilities
Accommodate generation options
Integration of small-scale, localized, or
on-site power generation allows
residential, commercial, and industrial
customers to self-generate and sell
excess power to the grid with minimal
technical or regulatory barriers. This
also improves reliability and power
quality, reduces electricity costs, and
offers more customer choice.
Optimize assets and Enable high
penetration of intermittent generation
sources.
Optimized power flows reduce waste and
maximize use of lowest-cost generation
resources.
Smart Grid technologies will enable power
systems to operate with larger amounts of
renewable energy resources since they
enable both the suppliers and consumers
to compensate for such intermittency.
FEATURES
Load adjustment
Demand response support
Greater resilience to loading
Decentralization of power generation
Price signalling to consumers
Load adjustment
The total load connected to the power grid
can vary significantly over time
A smart grid may warn all individual to
reduce the load temporarily or continuously
It predicts how many standby generators
need to be used, to reach a certain failure
rate
In the traditional grid, the failure rate can
only be reduced at the cost of more
standby generators
Demand response support
Allows generators and loads to interact
in an automated fashion in real time,
coordinating demand to flatten spikes
Allows users to cut their energy bills by
telling low priority devices to use energy
only when it is cheapest
Decentralization of power
generation
Distributed generation allows individual consumers
to generate power onsite
Allows individual loads to tailor their generation
directly to their load, making them independent
from grid power failures
If a local sub-network generates more power than
it is consuming, the reverse flow can raise safety
and reliability issues
Greater resilience to loading
Driving Factors for SMART GRID

Business Blocks of Smart Grid
SMART GRID – Bringing together enabling technologies, changes in
business processes, and a holistic view towards end-to-end
requirements of the grid operations.
Consumer-side capabilities and distributed generation technologies
form the base.
Achieving Benefit of Smart Grid
A large scale implementation of Smart Grid
will have an impact on many utility systems
and process spanning over customer
services, system operations, planning,
engineering and field operations.

Security Challenges
A recent project from security consultancy IOActive
determined that an attacker with $500 of equipment and
materials and a background in electronics and software
engineering could take command and control of the
[advanced meter infrastructure] allowing for the en
masse manipulation of service to homes and
businesses.
According to a report in the National Journal last year,
hackers in China may have already used what little
infotech intelligence there is on the current power grid to
cause two major U.S. blackouts.
Blackout attacks
Data theft
Billing frauds
The Road Ahead..
Greater co-ordination in deployment and security testing
Independent penetration testers
Independent third-party security assessments
Political Challenge
"Democratic congressional leaders and the Obama
administration indicated Monday" in "a clean energy
conference," which was "focused extensively on the
need for a national 'smart' grid," that "they will push for
greater federal authority
The Wall Street Journal notes that the move "raises the
prospect of conflict between federal energy regulators
and state and local authorities, which have typically
wielded extensive influence over decisions on the
construction and location of new transmission lines."
Utility giants say the U.S. government should have sweeping
powers to approve high-voltage lines, especially if they're
transporting renewable energy. While states would have
input," the Federal Energy Regulatory Commission "would
have the final say and could allocate the cost burden among
customers in various states.
What needs to be done..
Therefore, an understanding at the National level is required
for successful and quick implementation of a project of such
scale and scope. Greater transparency and solid policy
framework will be needed.
Financing Challenge
Installation of 3,000 miles of transmission lines to carry
renewable energy to population centers and 40 million
smart electric meters in homes across the United States.
Billions of dollars would be required for any nation of
comparable size to fund such a project.
Newly proposed legislation would limit FERC's ability to
allocate the costs of new transmission lines. Now FERC
chairman Jon Wellinghoff says he agrees that only those
who benefit from new lines should pay.
This makes it more expensive and difficult to finance new
projects.
Technological Challenge
Standardization
Energy Independence and Security Act of 2007. According to
Section 1305 of the act, this interoperability framework “shall
be flexible, uniform, and technology neutral” and “align
policy, business, and technology approaches in a manner
that would enable all electric resources, including demandside resources, to contribute to an efficient, reliable electricity
network.”
Some components, like the Power System Stabilizers (PSS)
installed on generators are very expensive, require complex
integration in the grid's control system, are needed only
during emergencies, but are only effective if other suppliers
on the network have them. Without any incentive to install
them, power suppliers don't.
Complex
Systems
Information
&
Communication
Most utilities find it difficult to justify installing a
communications infrastructure for a single
application (e.g. meter reading). Because of this, a
utility must typically identify several applications
that will use the same communications
infrastructure – for example, reading a meter,
monitoring power quality, remote connection and
disconnection of customers, enabling demand
response, etc
