    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

  • 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

  • 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.

  • 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;

  • 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

  • 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
