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

Present Grid Condition of Bangladesh


10/18

Increasing demand of electricity

Lack of fuel

Nonfunctional load dispatch center

Corruption in administration

High system losses

Delays in completion of new plants

Low plant efficiencies

Erratic power supply

Electricity theft

Blackouts

Shortages of funds for power plant maintenance

Problems of Bangladesh energy sector


11/18

Rudimentary phases to enable Smart Grid

planning at consumer-premise, AC/ DC feed-in and differentvoltage level coordinated development

Improving the functions and performance of existing system in

an integral manner

Tracking down the connections between different power grid

monitoring and controlling indexes

Assembling a logic structure based power system monitoring andcontrolling index system

Implementation of dynamic security monitoring, power system

pre-alarm processing and pre-control

Underscored sectors for smart grid

System Control and Optimization

Renewable and Distributed Energy Resources

(DER) Integration

Energy Storage Solutions

Customer-side Applications Communications Architecture

Efficient Manpower

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


15/18

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


16/18

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.


17/18

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
