9. PRESENT SCENARIO 9/12/2010 6

10. Today’s Grid Network • Fragmented, Isolated system Lack of standards • Security and system management sometimes underestimated • Integration of systems is difficult • Vendors selling proprietary systems 9/12/2010 7

11. And The Future … 9/12/2010 8

12. Tomorrow’s Power Grid •Requirements driven •Interoperability–The ability to “plug and work "devices and software •Open Architecture & Privatization –Non-proprietary infrastructure means no vendor lock-in –Because vendors compete, innovations will result •Based on Industry -Accepted Standards –Encourages confident infrastructure investment –Reduces risk of obsolescence 9/12/2010 9

13. GOALS OF SMART GRID Optimize grid use. Improve grid efficiency and security.  Better align demand with supply constraints and grid congestion.  Enable distributed generation (especially from renewable sources). Empower customers to manage their consumption and take advantage of pricing and supply options. 9/12/2010 10

14. Smart Grids: The Vision • Flexible: Fulfilling customers’ needs whilst responding to the changes and challenges ahead; • Accessible: Granting connection access to all network users, particularly for RES and high efficiency local generation with zero or low carbon emissions; • Reliable: Assuring and improving security and quality of supply, consistent with the demands of the digital age; • Economic: Providing best value through innovation, efficient energy management and ‘level playing field; 9/12/2010 11

21. Functioning Of Smart grid * Be able to heal itself * Motivate consumers to actively participate in operation of the grid. * Resist attack * Provide higher quality power that will save money wasted from outages * Accommodate all generation and storage options * Enable electricity markets to flourish * Run more efficiently 9/12/2010 14

22. Emphasis on Distributed Grid DG technology consists of modular and renewable-energy generators . It uses a few large-scale generating stations located far from load centres DG systems employ numerous, but small plants and can provide power onsite with little reliance on the distribution and transmission grid. DG technologies yield power in capacities that range from 30-15000 KWs 9/12/2010 15

23. DISTRIBUTED GRID NETWORK 9/12/2010 16

25. Offers efficiency gains for on-site applications.

26. Enables savings on electricity.

27. Provides a stand-alone power option.

28. Provides customers a choice in satisfying their particular energy needs. 9/12/2010 17

30. Responds to increasing energy demands.

31. Responds to pollutant emission concerns.

32. Provides low-cost, reliable energy essential to maintain competitiveness in the world market.

33. Creates numerous job opportunities.9/12/2010 18

34. Advantages Of HVDC & FACTS 1> Avoids technical problems in the power system > Increase transmission capacity & system stability very efficiently. 3> Reduce transmission losses by optimization of power flow 4> long distance transmission is healthier 5> Environment friendly 9/12/2010 19

35. Problems of Indian Power Grid * Poorly planned Distributed network * Over loading of system components * Lack of reactive power support & regulation services * Low metering efficiency & bill collection * Power theft 9/12/2010 20

36. Prospects of Smart Grid in India Smart grid implementation across India could reduce transmission and distribution losses by up to 30%. Reduces 95MtCO2, which amount to energy savings and carbon costs of 8.6bn Euro. Minimize the need for increased generation capacity Greater utilization of renewable and decentralized sources of energy generation. 9/12/2010 21
