WHAT IS GRID?
Anelectrical grid is an interconnected network
for delivering electricity from suppliers to
consumers
Grid is a term used for an electricity network
which may support all or some of the following
three distinct operations:
Electricity generation
Electric power transmission
Electricity distribution

WHAT IS SMART GRID?
Asmart grid delivers electricity from suppliers
to consumers using two-way digital technology to
control appliances at consumers' homes to save
energy, reduce cost and increase reliability and
transparency.
A smart grid includes an intelligent monitoring
system that keeps track of all electricity flowing
in the system.

When power is least expensive a smart grid could
turn on selected home appliances such as
washing machines or factory processes that can
run at arbitrary hours.
At peak times it could turn off selected
appliances to reduce demand.

OLD GRID VS SMART GRID
Old Grid
• You call when the power goes out.
• Utility pays whatever it takes to meet peak demand.
• Difficult to manage high Wind and Solar penetration
• Cannot manage distributed generation safely.
• 10% power loss in T&D Smart Grid
• Utility knows power is out and usually restores it
automatically.• Utility suppresses demand at peak. Lowers cost.
• Can manage distributed generation safely.
• Power Loss reduced by 2 %, lowers emissions &customer bills.

FEATURES OF SMART GRID:
Load adjustment
Demand response support: Demand response support allowsgenerators and loads to interact in an automatedfashion in real time, coordinating demand toflatten spikes.

Greater resilience to loading
Decentralization of power generation
Price signaling to consumers:
During off-peak time the price is reduced
significantly, primarily for heating storage
radiators or heat pumps with a high thermalmass, but also for domestic appliances

TECHNOLOGY USED IN SMART
GRID:
Integrated communications:
Integrated communications will
allow for real-time control, information and data
exchange to optimize system reliability, asset
utilization, and security.
Sensing and measurement:
Core duties are evaluating congestion
and grid stability, monitoring equipment health,
energy theft prevention, and control strategies
support

Measurement used in smart grid are:
• Advanced microprocessor meters
• Dynamic line rating measurement
• Electromagnetic signaturemeasurement/analysis
• Advanced switches and cables
• Digital protective relays

Smart meter:
Asmart meter is an advanced
meter (usually an electrical meter) that
identifies consumption in more detail
than a conventional meter; and
optionally, but generally, communicates
that information via some network back
to the local utility for monitoring and
billing purposes

Phasor measurement units:
High speed sensors called PMUs distributed
throughout their network can be used to monitor
power quality and in some cases respond
automatically to them.
A Wide-Area Measurement Systems
(WAMS) is a network of PMUS that can provide
real-time monitoring on a regional and national
scale.

Resist attack:
One of the most important issues of resist
attack is the smart monitoring of power grids,
which is the basis of control and management of
smart grids to avoid or mitigate the system-wide
disruptions like blackouts.
High quality power

Accommodate generation options:
As smart grids continue to support
traditional power loads they also seamlessly
interconnect fuel cells, renewables,
microturbines, and other distributed generation
technologies at local and regional levels.
Enable electricity market:
Significant increases in bulk
transmission capacity will require improvements
in transmission grid management

Optimize assets:
A smart grid can optimize capital assets
while minimizing operations and maintenance
costs.
Enable high penetration of intermittent
generation sources:
Smart Grid technologies will enable power
systems to operate with larger amounts of such
energy resources since they enable both the
suppliers and consumers to compensate for such
intermittency.
