Demand Side Management of a Smart Grid

  1. 1. Final Year Seminar National Institute Of Technology, Hamirpu   Prepared By : Mirza Abdul Waris Beigh Roll No: 10289
  2. 2.  Smart Grid is the modernization of the electricity delivery system so that it monitors, protects and automatically optimizes the operation of its interconnected elements.  Smart grid is the integration of information and communications system into electric transmission and distribution networks.  The flow of electricity from utility to consumer becomes a two-way conversation i.e. two way flow of information.
  3. 3.  India is having one of the weakest electrical grids in the world  10 to 20 % of power is lost to THEFT across the utilities in India.  15-20% power transmitted is lost in the transmission and distribution network  Huge commercial losses due to poor billing, metering, collection at depth etc
  4. 4. Proactive management of electrical network during emergency situations. Better demand supply / demand response management. Better power quality Reduce carbon emissions. Increasing demand for energy : requires more complex and critical solution with better energy management
  5. 5. Self-healing: The grid rapidly detects, analyses, responds, and restores  Empowers and incorporates the consumer  Tolerant of attack: The grid mitigates and is resilient to physical/cyber-attacks  Provides power quality needed by 21st-century users: The grid provides quality power consistent with consumer and industry needs  Accommodates a wide variety of supply and demand.  Fully enables and is supported by dynamic 
  6. 6. Smart Grid in Power Sector •Asset Management Transmission Distribution System Operations •HVDC and UHVAC etc. •Advance Metering Infrastructures •Asset Management etc. •Self Healing Grids •WAMS •Adaptive Islanding etc.
  7. 7.  Smart Metering –  Automatic, Time of Use, Consumer Communication & Load Control  Communications : Automated Metering Infrastructure (AMI) – LAN, WAN, HAN  DRMS (Demand Response Management)  In Home enabling technology o Demand in three category: • Immediate, Deferrable, Storable o Customer aggregation & De-aggregation required for Peak shifting
  8. 8.  Enhance power system measurements and enable the transformation of data into information.  Evaluate the health of equipment, the integrity of the grid, and support advanced protective relaying.  Enable consumer choice and demand response, and help relieve congestion
  9. 9.  Advanced Metering Infrastructure (AMI) o Provide interface between the utility ad its customers: bi-direction control o Advanced functionality • Real-time electricity pricing • Accurate load characterization • Outage detection/restoration
  10. 10.  Health Monitor: Phasor measurement unit (PMU) o Measure the electrical waves and determine the health of the system. o Increase the reliability by detecting faults early, allowing for isolation of operative system, and the prevention of power outages.
  11. 11. The Key to Effective Demand Side Management
  12. 12.  AMI is a basic element of the smart grid; its role is to furnish information and active interactive capability to service providers and customers  AMI consists of smart meters, integrated two way communications infrastructure, active customer interface, and meter data management system to gather and store customer data  In addition, AMI provides interfaces to other electricity company enterprise systems
  13. 13.  The smart meter is the central nervous system of the AMI  The ability to collect consumption data in discrete time intervals allows the utilities to charge time differentiated rates for electricity usage  The meter can also perform other useful advanced functions, such as remote connect/disconnect  The meter is also a key need in the
  14. 14.  Direct Load Management:  Direct Load Control  Interruptible tariff  Demand Bidding  Indirect Load Management:  Pricing programs  Rebates  Education programs  The financial status of power sector can be effectively improved by demand side management
  15. 15. Changes in electric usage by end-use customers in response to changes in the price of electricity over time is expected to produce major changes from normal consumption patterns. This will help the utilities in undertaking effective management of power distribution.
  16. 16.  Energy Usage Information  Efficient Communication between Utilities and Customers  Consumer Enrollment in DR programs  In Home Technology- Availability & Purchase , Device Provisioning
