What is Smart Grid?
A smart grid is the technology that incorporates
advanced sensing technologies, control systems and
integrated communications into the existingelectricity grid.
Smart Grid is incomparable to the existing grid in
the aspects of smart central generation, smart
transmission, smart substation, smart distribution
feeders and smart metering

Decentralization
Substation: Information gatheringand decision making
Electricity dispatching center:strategic management of gridintelligence
Computerized management:transmission and distribution
To form grids which are more smart, receptiveand flexible than present power grids, Smart
grid employ decentralization process

Why the Grid needed to be Smart?
To deal with the mounting energy demand of theworld
To lessen the cost of power disturbances andsystem losses throughout the world
To reduce CO2emission by enhancing Greenenergy generation and consumption
To stop Electricity price hiking by controlling demandand supply
To provide reliable services for a long period by
removing aged infrastructure and employees

What does a Smart Grid do?
Allows duplex electricity flow based on availableinformation and consumer preferences
Brings renewable energy to the traditional grid
Permits fast load relief to cope with fluctuations in
generation
Brings rises in energy efficiencies and drops in carbon
emissions
Develops the reliability, performance and overallefficiency of the utility
Enables consumer empowerment to manage their energy
usage and financial savings

Consequence of Smart Grid implementation
in Bangladesh
improve the efficiency and reliability of electrical power
distribution system
establish long-distance and large-capacity power transmissionsystems
diminish the bulk of energy in the cities and the pressure of
transmission by decentralization
Reduce environmental pollution
accelerate the renovation of national economy

Smart grid:
potential solution of power failure
Smart grid can spontaneously recalculate and
distribute electricity to all consumers equitably but
at reduced amount leaving no premises withoutelectricity in case of load-shedding
Digital radios and R/C circuit breakers can be set
up to optimize energy flow for wirelessly control
of electricity distribution and energy conservation

Digital radio and R/C circuit breakers
Locally manufactured Digital radios and circuit
breakers can be implemented to the
distribution system for automatic control andmanagement of the power grid
A lot of circuit breakers are needed tomaintain the power system stability, cable and
transformer protection, load balancing and
network stability

How do Digital radio and R/C circuit
breakers work?
Throughout energy shortages, the Smart grid
radio transmitters, installed at the electrical
poles or sub-stations, will broadcast encoded
message over the air to radio receiver,
attached to distant circuit breakers.
This encrypted message will switch off only afraction of electricity supplied to various
destinations.

Advantages of new digital radio
technologies
1. Almost no change to existing electrical wiring
2. Very low cost and small Radio Transmitters and
Receivers3. License-free radio band
4. Greater employment chance by designing and
manufacturing both digital radios and circuitbreakers locally
5. Become a pioneer of smart grid in third world
countries
