             What is Smart Grid?
     Many Definitions -
        •   A smart grid includes an intelligent monitoring
            system that keeps track of all electricity flowing in
            the system. It also incorporates the use of
            superconductive transmission lines for less power
            loss, as well as the capability of integrating
            alternative sources of electricity such as solar and
            wind.

        •   “an automated, widely distributed energy delivery
            network characterized by a two-way flow of
            electricity and information, capable of monitoring and
            responding to changes in everything from power
            plants to customer preferences to individual
            appliances.”

             Why Smart Grid? Drivers for SG
             1.Rising costs of capital, raw materials, and
                labour

              2.Aging infrastructure and workforce

              3.Continuing national security concerns

              4.Need for and viability of energy efficiency
                caused by the expansion of the global
                economy

              5.Increasing awareness of environmental
                issues, including global warming

         Renewable Energy in Smart Grid

    •   Energy, Environment & Sustainable Development –
        interlinked.
    •   Coal (fossil) fuel – limited period
    •   Reduce green house emissions & mitigate climate change.
    •   Peak load management
    •   Distributed Generation Systems connected to LT Distribution
        system (11kV)
    •   Renewable energy sources-
        • Wind
        • Solar – Rooftop Photovoltaic
        • Other Distributed Generation systems based on Mini Hydro,
            & Bio mass

     Integration Issues

     • Large number of DG units interconnection to
       conventional grid affects the stability.
     • Customer can also inject energy into grid-
       bidirectional flow of energy- energy meter shall
       support bidirectional flow of energy recording.
     • Energy recording, tariff and      billing – to be
       reworked.
     • Real time monitoring and Control.
       •     Smart Grid addresses above- convergence                      of
             Information and communication Technology

                           Standardization Issues

     • Various organizations (NIST, IEEE, IEC,
       BIS etc)     are in the process of
       standardizing SG requirements – in
       various phases
     • Mostly involved with identifying the set of
       existing standards and revision wherever
       necessary
