 A smart grid is an umbrella
term that covers
modernization of both the
transmission and distribution
grids. http://en.wikipedia.org
 Smart Grid is a new market
being built around the
modernization of the
electrical grid, green power
generation and more efficient
usage of electrical power.

is not a thing or a specific
project. It is about how the utilities leverage
technology to enhance their entire
portfolio of business processes.”

• Xcel Energy’s vision of a Smart Grid includes a fully network-connected
system that identifies all aspects of the power grid and communicates
its status and the impact of consumption decisions (including
economic, environmental and reliability impacts) to automated
decision-making systems on that network.
• This vision leverages the multitude of vertical system solutions
currently available and deploys a horizontal integration of these
systems into a real-time, automated “neural network” that will manage
all of the variables involved in delivering energy to the consumer.
• We believe this vision of an advanced decision-making system will
allow Xcel Energy to more efficiently deliver energy while providing
consumers with valuable information for better decisions on when,
where and how to consume energy.
• The impact will be a greatly improved delivery system that optimizes
the impact on the environment, ensures the most efficient delivery, and
maximizes reliability.
As defined by large utilities in the
USA
• Duke Energy’s long-term vision is to transform the
operation of its electric power grid by creating a
reliable and scalable networked infrastructure capable
of delivering and receiving information from
intelligent devices distributed across its power
systems, automating components of the distribution
systems and leveraging the linked networks for
improved operational efficiencies and customer
satisfaction.
• Duke Energy is 3rd largest utility in USA (Kwhr

“ Green power” ; new high tech jobs; new business
Utility owners and their desire for increased return on
investment with reduced operating costs and improved
reliability and quality of supply. (QOS)
Operations management and their desire to lower
operating costs and integrate new technology
Engineering management and their desire to modernize
the network and it’s operation with new technology
Technology advances in almost every aspect of the utility
business that have not been adopted because of the
extreme conservative nature of the electrical utility
business.

WWW SmartGrid market growth
The intelligent grid utilizes
technology in three important ways:
• 1) Automating the grid to harden it and make it less
costly to operate.
• 2) Integrating the electric grid to create an end-to-end
network for quickly acquiring and transporting data
from millions of end points
• 3) Expanding the value of the grid beyond typical
utility needs to support new services and new markets
offered by energy retailers.

Some of the Standards for SmartGrid
Comparison Current Grid to Smart
Grid
Smarter Grid today
 - Substation automation (SA) enables utilities to plan,
monitor, and control equipment in a decentralized
way, which makes better use of maintenance budgets
and boosts reliability.
 - Smart meters allow utility customers to participate
in time-of-use pricing programs and have greater
control over their energy usage and costs.

Smarter Grid beginings
 Smart grid technologies in use today Utility companies are
already implementing “smart” devices in various ways.
Some examples of how smart technologies—and the
practices they enable—can impact the operation and
overall health of the grid include the following:
 - Real-time situational awareness and analysis of the
distribution system can drive improved system operational
practices that will, in turn, improve reliability.
 - Fault location and isolation can speed recovery when
outages do occur by allowing work crews to drastically
narrow the search for a downed line.

Smarter grid today
 - SCADA/DMS (distribution management systems) put
more analysis and control functions in the hands of grid
operators.
 - Voltage control, through reactive power compensation
and the broader application of power electronics,
increases transmission capacity of existing lines
improves the resiliency of the power system as a whole.
