The document discusses smart grids, which use digitally controlled, two-way communication systems to improve the efficiency, reliability, and safety of electricity delivery. A smart grid is capable of sensing overloads, rerouting power to prevent outages, integrating new technologies, and accepting more renewable energy through features like smart meters, superconducting transmission lines, and digital power controllers. While a smart grid could reduce costs and emissions, challenges to its adoption include a lack of test beds and high expenses relative to traditional electricity infrastructure upgrades.

- 2. CONTENTS What is SMART GRID? Need of smart grid Past cities Technical overview Optimistic sides Challenges
- 3. SMART GRID It is a network for electricity transmission and distribution systems that uses two-way, web- enabled, digitally controlled, automated analysis of problems & automatic switching capabilites to improve the efficiency, reliability and safety of electricity delivery and use.
- 5. intelligenT Capable of sensing system overloads Rerouting power to prevent or minimize a potential outage of working autonomously when conditions require resolution Faster than humans can respond Cooperative in aligning goals of utilities & consumers.
- 7. accomodating Capable of integrating any and all better ideas & technologies.
- 8. Digitally controlled Communication at every level is essential. Digital technologies have transformed other industries like telecommunication. Same change is expected for electric grid.
- 9. Automatic switching capabilities According to demand it switches to required resources in order to upgrade the grid.
- 10. opportunistic Creating new opportunities and markets by means of its ability to capitalize on plug-and-play innovation wherever and whenever appropriate.
- 11. green Reduces dependency on fossil fuels and emission of pollutants. Capability of grid to accept large contribution of renewable energy resources.
- 12. NEED OF SMART GRID Consumer visibility. Increase of demand by 2030. Avoid blackouts and brownouts. Overcome non-linear behavior. Cleaner electricity.
- 13. Past cities Telegestore project of Italy is the largest & earliest smart grid project. Home automation network was installed in Boulder, Colorado. SA Habitat & Valency Energy Company came up with home automation at the outskirts of Hyderabad.
- 14. Technical overview 1. Smart meters. 2. HTSC Technology. 3. Digital power controllers. 4. Liquid hydrogen pipelines. 5. Quantum nano transmission wire.
- 16. SMART METERS Enabling technology that makes it possible to extract value from two-way communication.
- 17. HTSC TECHNOLOGY HTSCs have no resistance to electricity flow at supercritical temperatures. Provide the capability to smooth out intermittent and unpredictable flow.
- 18. Digital power controllers HTSC, thyristors, and capacitors together with distributed generation and distributed storage .
- 19. QUANTUM NANO TRANSMISSION WIRES QW has electrical conductivity higher than copper, at one sixth the weight, and twice the strength of steel. No line losses and the grid could be buried without any special handling
- 20. Lh2 pipelines High-capacity, superconducting power transmission cable of nano grade cooled with in a liquid hydrogen pipeline.
- 21. OPTIMISTIC SIDES
- 22. CHALLENGES No test beds Quite expensive Electricity industry lowest R&D expenditures
- 23. GIVEN ENOUGH ANTS, WE CAN MOVE A MOUNTAIN.
