  2. 2. What is Smart grid? A smart grid puts information and communication technology into electricity generation, delivery, and consumption, making systems cleaner, safer, and more reliable and efficient. U.S. Department of Energy Definition: A smart grid integrates advanced sensing technologies, control methods, and integrated communications into the current electricity grid. 2 Department of Electrical and Electronics Engineering,AITAM,Tekkali
  3. 3. Some Smart Grid Definitions  “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.”  “A smart grid is the electricity delivery system (from point of generation to point of consumption) integrated with communications and information technology”  A smart grid is a modernized electrical grid that uses analog or digital information and communications technology to gather and act on information - such as information about the behaviors of suppliers and consumers - in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity. Electronic power conditioning and control of the production and distribution of electricity are important aspects of the smart grid. 3 Department of Electrical and Electronics Engineering,AITAM,Tekkali

  11. 11. CHARACTERISTICS OF SMART GRID  Intelligent – capable of sensing system overloads and rerouting power  Efficient – capable of meeting increased consumer demand without adding infrastructure  Accommodating – accepting energy from virtually any fuel source including Solar and wind as easily and transparently as coal and natural gas  Motivating – enabling real-time communication between the consumer and utility  Opportunistic – creating new opportunities and markets  Resilient – increasingly resistant to attack and natural disasters  “Green” – slowing the advance of global climate change and offering a genuine path toward significant environmental improvement
  12. 12. Smart-grids for India  Has to do much more than what is done elsewhere  Smart-grids in India is to be used to  Enable decentralized power-generation and optimize usage  Explore alternate methods of storage, including storage of heat (cool)  Handle peak-demand better  Manage demand and supply to meet creatively at all points of time, by using storage and high-cost instantaneous power-sources  At local level  At neighborhood level  At district level, at state level, at national level  Intelligently decide where to do load shedding if no other options  enable time of day metering with remote monitoring 12 Department of Electrical and Electronics Engineering,AITAM,Tekkali
  13. 13. Integrated Communications and Security  High-speed, fully integrated, two-way communication technologies that make the smart grid a dynamic, interactive “mega-infrastructure” for real- time information and power exchange.  Cyber Security: the new communication mechanism should consider security, reliability, QoS. 13 Department of Electrical and Electronics Engineering,AITAM,Tekkali
  14. 14. Smart Grid Benefits  Economic Development  New Jobs: The manufacture, installation, operation and maintenance of the smart grid and its components will create new jobs within the state.  Innovation: Smart grid innovation will enable the growth of business while rewarding customers with valuable new products.  Lower Costs: Costs rise over time and energy is no exception, but the smart grid should provide less costly energy than otherwise would be possible. As such, it will save customers money which can be invested or consumed as they choose. 14 Department of Electrical and Electronics Engineering,AITAM,Tekkali
  15. 15. Smart Grid Benefits-cont  Customer Satisfaction  Higher Customer Satisfaction: The combination of lower costs, improved reliability and better customer control will raise satisfaction among all types of customers (residential, commercial, industrial, institutional).  Improved Reliability: Smart grid will reduce and shorten outages and improve the quality of power.  Customer Energy/Cost Savings: As pricing becomes more transparent and is aligned with the underlying economics of generation and distribution, customers’ decisions to save money will benefit society as well  Highest Security: Security will be incorporated into the design of the smart grid and will require the implementation of practices and procedures by individual stakeholders. In this way, the physical and cyber security risks can be managed to the highest standards possible. 15 Department of Electrical and Electronics Engineering,AITAM,Tekkali

  18. 18. Key Challenges  Government Support – funding and to ensure development  National Road Map adopted and must implementation  Access of financial resources particularly due to poor financial health of the power utilities  Lack of Policy and Regulation related to Smart Grid applications  No proven commercial viability of large scale smart grid implementation – Cost and benefit assessment (Most of the initiatives are pilots)  Development of Smart Grid Standards including pilot models that can be adopted by discoms based on their level of maturity to handle such applications  Ability of users to absorb implementation of advanced technology  Lack of awareness requiring knowledge creation, training and capacity building of both the utility and consumers 18 Department of Electrical and Electronics Engineering,AITAM,Tekkali
  19. 19. Way Forward  Goals in the National Road Map to be accompanied by implementation structure and mechanisms  Need for coordinated development nationally as well with international bodies  Development of SG Regulations: Optimal regulatory response is of immense importance to make the overall initiative successful and attractive to all parties  Need for creating awareness and acceptance of Smart Grid technologies  Process support to demonstrate commercially viable pilots to demonstrate success and dissemination of such initiatives to other utilities/users  Need to undertake initiatives to encourage indigenous vendor development for reduction of costs and ensure long-term service support 19 Department of Electrical and Electronics Engineering,AITAM,Tekkali
  20. 20. Risks and Challenges to SmartGrid Concept Implementation Unknown cost to complete. Total cost may be more than benefits. AMI works but SmartGrid technologies may be years in development. Regulatory policy is undefined therefore uncertain. Technical terminology is confusing to non-technical users. The scope of the national SmartGrid project may be too large. The SmartGrid concept is not “universally” accepted in the U.S. Security question of the day: Is one large grid easer to take out than several small grids? Hacksaw, virus, etc. Department of Electrical and Electronics Engineering,AITAM,Tekkali
  21. 21. Conclusion  Smart Grid provides intelligent, advanced power control for the next century  Many new technologies involve for supporting sensing, controlling, human interfaces.  Charging electricity cost is fundamental infrastructure can be implemented similar to stock market in smart grid.  This smart grid technology is new and initial cost is more and we don’t know that Present Infrastructure is adequate or not.  Cyber Security: the new communication mechanism should consider security, reliability, QoS. 21 Department of Electrical and Electronics Engineering,AITAM,Tekkali
