our current electric grid was conceived
more than 100 years ago when electricity
needs were simple power generation was
localized and built around communities
most homes had only small energy demands
such as a few light bulbs in a radio the
grid was designed for utilities to
deliver electricity to consumers homes
and then build them once a month
this limited one-way interaction makes
it difficult for the grid to respond to
the ever-changing and rising energy
demands of the 21st century the smart
grid introduces a two-way dialogue where
electricity and information can be
exchanged between the utility and its
customers it's a developing network of
communications controls computers
automation and new technologies and
tools working together to make the grid
more efficient more reliable more secure
and greener this smart grid enables
newer technologies to be integrated such
as wind and solar energy production and
plug-in electric vehicle charging with
our participation as informed consumers
this smart grid will replace the aging
infrastructure of today's grid and
utilities can better communicate with us
to help manage our electricity needs the
smart home communicates with the grid
and enables consumers to manage their
electricity usage by measuring a home's
electricity consumption more frequently
through a smart meter utilities can
provide their customer with much better
information to manage their electricity
bills
inside the smart home a home area
network
orhan connects smart appliances
thermostats and other electric devices
to an energy management system smart
appliances and devices will adjust their
run schedule to reduce electricity
demand on the grid at critical times and
|
|
lower consumers energy bills these smart
devices can be controlled and scheduled
over the web or even a TV renewable
resources such as wind and solar are a
sustainable and growing source for
electric power however renewable power
sources are variable by nature and add
complexity to normal grid operations the
smart grid provides the data and
automation needed
to enable solar panels and wind farms to
put energy onto the grid and optimize
its use to keep up with constantly
changing energy demands utilities must
turn power plants on and off depending
on the amount of power needed at certain
times of the day the cost to deliver
power depends on the time of day it is
used electricity is more costly to
deliver at peak times because additional
often less efficient power plants must
be run to meet the higher demand this
smart grid will enable utilities to
manage and moderate electricity usage
with the cooperation of their customers
especially during peak demand times as a
result utilities will be able to reduce
their operating costs by deferring
electricity usage away from peak hours
and having appliances and devices run at
other times electricity production is
more evenly distributed throughout the
day the power being used right now was
generated less than a second ago many
miles away at each instance the amount
of electricity generated must equal the
consumption across the entire grid Smart
Grid technologies provide detailed
information that enables grid operators
to see and manage electricity
consumption in real time this greater
insight and control reduces outages and
lowers the need for peak power in
control rooms across the grid engineers
will be able to more precisely and
predictably manage electricity
production reducing the need to fire up
costly secondary power plants the
distribution system routes power from
the utility to residential and
commercial customers through power lines
switches and transformers utilities
typically rely on complex power
distribution schemes and manual
switching to keep power flowing to their
customers any break in this system
caused by storms bad weather or sudden
changes in electricity demand can lead
to outages the smart grids distribution
intelligence counters these energy
fluctuations and outages by
automatically identifying problems in
rerouting and restoring power delivery
utilities can further use distribution
intelligence to predict in
electricity usage with the cooperation
of their customers leading to lower
production cost the charging of a
plug-in electric vehicle can be managed
over a home area network or Han the Han
can balance the demand for electricity
across the household and prioritize
between the electric vehicle and other

appliances to manage electricity usage
and reduce costs with Smart Grid
technologies and consumer participation
utilities can more easily handle the
increased demand for power to run the
electric vehicles and ensure charging
needs are met by adding more plug-in
electric vehicles to the grid we have
the potential to reduce fuel costs lower
our dependency on foreign oil and help
reduce greenhouse gas emissions
