  3. 3. ABSTRACT Ǿ The development and implementation of a smart grid for power supply is one of the pressing issues in modern energy economy, given high national priority and massive investments, although the entire subject is still in its infancy stage. Ǿ The smart grid delivers electricity from producers to consumers using two-way digital technology, and allows control of appliances in the consumers' houses and of machines in factories to save energy, while reducing costs and increasing reliability and transparency. Ǿ In principle, the smart grid is an upgrade of the common electricity grids that operate mostly to provide one-way power from several major power plants to a large number of Consumers. Ǿ The smart grid could be at the city level, integrate into a national grid, or at the plant level, integrated into the urban grid ready for the future. 3
  4. 4. 4 THE GRID TODAY Utilities committed to proving safe, reliable power. Must provide quality service with an aging infrastructure. Supplying energy in a carbon constrained world. Working with non-integrated systems and processes. SMART TECHNOLOGIES CAN PROVIDE SOLUTIONS TO MODERN GRID CHALLENGES.
  5. 5. 5 “Analog” Grid Centuries-Old Design
  6. 6. 6 “Smart” Grid Digital Intelligence infused throughout the Grid Energy storage devices Local power generation Digital sensors and controls Real-time data Real-time price signals Broadband communications Smart Homes Smart Buildings Electric transportation
  7. 7. 7 NECESSITY OF SMART GRID  Grid reliability  Aging assets, heightened load  Environment:  Global climate concerns  State mandates for green power  Energy Security:  Homeland security  Dependence on foreign oil  Customer Choices:  Growing needs and expectations  Desire for greater flexibility and options
  8. 8. 8 FEATURES The Smart Grid will: Be more reliable. Be self-healing and self-monitoring. Be more secure. Be cleaner and greener. Support widespread distributed generation. Help customers better control energy use in their homes and businesses. Achieve lower throughput, thus lowering prices.
  9. 9. 9 Smart Grid City Involves the entire energy pathway from the power source to the home and all points in between Rich in IT High-speed, real-time, two-way communications Sensors enabling rapid diagnosis and corrections Dispatched distributed generation (PHEVs, wind, solar) Energy storage & In-home energy controls Automated home energy use
  10. 10. 10 SMART GRID TECHNOLOGY PROJECTS  Power Production  Energy storage  Distributed generation  Utility Operations  Smart Outage Management  Smart Distribution Assets  Smart Substations  Consumer  Smart House  Plug-in Hybrid Electric Vehicles

  12. 12. 12 ENERGY STORAGE Scenario: Wind, solar energy can be stored in a battery for use when needed.  Consumers can use wind power when they want—not just when the wind is blowing.  Energy storage devices can be tapped whenever demand is high.
  13. 13. 13 SMART SUBSTATION SCENARIO: Digital intelligence gives substation operators remote control of facilities. Allows faster adjustments to conditions. Prevents blackouts, makes for faster recovery. More flexibility to re-route power. Monitors help keep facilities and sites secure.

  15. 15. 15 SMART DISTRIBUTION ASSETS SCENARIO:  A smart meter detects an isolated outage in a residential neighborhood. The utility pings the meter and is able to send the right crew, with the right tools, to the right location to turn power back on quickly, OR Can remotely re-connect power Faster restoration time and fewer outage minutes
  16. 16. 16 SMART HOUSE SCENARIO:  Home appliances contain onboard intelligence that receives signals from power grid control systems and can reduce demand when the grid is under stress.  Consumers automatically pre-program appliances to turn on when prices are lower.  Creates options for managing bills and energy consumption habits
  17. 17. 17 SCHEMATIC REPRESENTATION Plug-in hybrid electric cars Added green power sources Smart thermostats, appliances and in-home control devices Real-time and green pricing Signals High-speed, networked connection s Customer interaction with utility
  18. 18. 18 SMART GRID BENEFITS
  19. 19. 19
  20. 20. 20 INVESTMENT Approximately $60 to $100 million Cost is offset by joint funding from partners and contributions of: Utility hardware IT hardware Software Labor resources
  21. 21. 21 CONCLUSION It won’t happen all at once: Smart Grid will be an evolution with long-term implications. Start up costs involved; but savings expected in the long run. Solid focus will remain on Government’s response rather than customer choice.
