  11. HISTORY

  12. Grid is a term used for an electricity network which may support all or some of the following four distinct operations. Electricity generation Electric power transmission Electricity distribution Electricity control. grid

  13. History of smart grid. • Technological improvements of the power system largely rose in the 50s and 60s. • Nuclear power, computer controls helped fine tune the grid’s effectiveness and operability. • With today’s technology such as wireless protocol, network infrastructure the power grid becomes smart grid, capable of recording, analyzing and reacting to transmission data, allowing for efficient management of resources, and cost-effective appliances for consumers.

  14. History of smart grid. • 1980s, Automatic meter reading was used • 1990s, Advanced Metering Infrastructure. • Smart meters used to monitor in real time. • 2000, Italy's Telegestore Project - to network (27 million) of homes using smart meters. • Project cost of 2.1 bn euro annual savings of 500 mn euro

  15. MODERNIZATION OF T&D

  16. Smart Grid: Transmission and Distribution • Smart Meters: possible for energy suppliers to charge variable electric rates • Peak curtailment/leveling and time of use pricing • Platform for advanced services • Provide reliability and power quality for the 21st century • Effective routine operations • Effective system planning capabilities

  17. The Current T&D System

  18. The Modern T&D System

  19. Smart Grid Technology Areas • Advanced Metering Infrastructure (AMI) • Smart Meters • Two-way Communications • Consumer Portal • Home Area Network • Meter Data Management • Demand Response • Advanced Distribution Operations (ADO) • Distribution Management System with advanced sensors • Advanced Outage Management (“real-time”) • Distribution Automation • Advanced Transmission Operations (ATO) • Substation Automation • Geographical Information System for Transmission • Wide Area Measurement System (WAMS) • Hi-speed information processing • Advanced protection and control • Modeling, simulation and visualization tools • Advanced Asset Management (AAM) • Advanced sensors • Integration of real time information with other processes

  20. AEF Study T&D Findings

  21. FUNCTIONS

  22. Funtions of Smart Grid Self-healing • Using real-time information from embedded sensors and automated controls to anticipate, detect, and respond to system problems, a smart grid can automatically avoid or mitigate power outages, power quality problems, and service disruptions

  23. Consumer participation •   This takes shape in two forms – electricity production and electricity consumption.  One of the many benefits of the Smart Grid is its ability to integrate renewable energy sources into large scale electricity production.   • Another is the ability to communicate in real time on a broad scale to signal requests to modify electricity consumption.  Both of these benefits have profound, positive impacts for consumers.

  24. Resist attack / Electricity Theft. • Smart grid technologies better identify and respond to man-made or natural disruptions. Real-time information enables grid operators to isolate affected areas and redirect power flows around damaged facilities

  25. Accommodate generation options • Integration of small-scale, localized, or on-site power generation allows residential, commercial, and industrial customers to self-generate and sell excess power to the grid with minimal technical or regulatory barriers. This also improves reliability and power quality, reduces electricity costs, and offers more customer choice.

  26. Optimize assets and Enable high penetration of intermittent generation sources. • Optimized power flows reduce waste and maximize use of lowest-cost generation resources. • Smart Grid technologies will enable power systems to operate with larger amounts of renewable energy resources since they enable both the suppliers and consumers to compensate for such intermittency.

  27. FEATURES

  28. Features

  29. Load adjustment • The total load connected to the power grid can vary significantly over time • A smart grid may warn all individual to reduce the load temporarily or continuously • It predicts how many standby generators need to be used, to reach a certain failure rate • In the traditional grid, the failure rate can only be reduced at the cost of more standby generators

  30. Demand response support • Allows generators and loads to interact in an automated fashion in real time, coordinating demand to flatten spikes • Allows users to cut their energy bills by telling low priority devices to use energy only when it is cheapest

  31. Decentralization of power generation • Distributed generation allows individual consumers to generate power onsite • Allows individual loads to tailor their generation directly to their load, making them independent from grid power failures • If a local sub-network generates more power than it is consuming, the reverse flow can raise safety and reliability issues • Greater resilience to loading

  32. Information Systems and ManagementinSMART GRIDS

  33. Driving Factors for SMART GRID • Reliability and Quality and Supply • Aging infrastructure of Transmission and Distribution Networks • The Environment • Distributed resources – Renewable sources • Demand side Management • Operational Excellence • Information Management • Automation

  34. Business Blocks of Smart Grid SMART GRID – Bringing together enabling technologies, changes in business processes, and a holistic view towards end-to-end requirements of the grid operations. Consumer-side capabilities and distributed generation technologies form the base.

  35. Achieving Benefit of Smart Grid • A large scale implementation of Smart Grid will have an impact on many utility systems and process spanning over customer services, system operations, planning, engineering and field operations. • Key requirements: • Systems Interoperability • Information Management • Data Integration

  36. Systems Involved in Distribution Smart Grid Distributed Resources Distribution Automation Advanced Metering Infrastructure

  48. CHALLENGES FOR SMART GRID

  49. Security Challenges • A recent project from security consultancy IOActive determined that an attacker with $500 of equipment and materials and a background in electronics and software engineering could take command and control of the [advanced meter infrastructure] allowing for the en masse manipulation of service to homes and businesses. • According to a report in the National Journal last year, hackers in China may have already used what little infotech intelligence there is on the current power grid to cause two major U.S. blackouts.

  50. Blackout attacks • Data theft • Billing frauds The Road Ahead.. • Greater co-ordination in deployment and security testing • Independent penetration testers • Independent third-party security assessments
