  2. A smart grid is the technology that incorporates advanced sensing technologies, control systems and integrated communications into the existing electricity 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

  3. To deal with the mounting energy demand of the world • To lessen the cost of power disturbances and system losses throughout the world • To reduce CO2 emission by enhancing Green energy generation and consumption • To stop Electricity price hiking by controlling demand and supply • To provide reliable services for a long period by removing aged infrastructure and employees

  4. What does a Smart Grid do? • Allows duplex electricity flow based on available information 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 overall efficiency of the utility • Enables consumer empowerment to manage their energy usage and financial savings

  5. 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

  6. Rudimentary phases to enable Smart Grid • planning at consumer-premise, AC/ DC feed-in and different voltage 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 and controlling index system • Implementation of dynamic security monitoring, power system pre-alarm processing and pre-control

  7. 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

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

  9. 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 without electricity 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

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

  11. 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 a fraction of electricity supplied to various destinations.

  12. Advantages of new digital radio technologies • Almost no change to existing electrical wiring • Very low cost and small Radio Transmitters and Receivers • License-free radio band • Greater employment chance by designing and manufacturing both digital radios and circuit breakers locally • Become a pioneer of smart grid in third world countries

  13. Smart substations for Bangladesh • Reports information such as electricity consumption • Performs switchboard operation • Gives decision making back to the electricity dispatching control center
