Smart grid

  1. 1. SMART GRID BIET JHANSI Under the Guidance of Submitted By Dr. Mahendra Kumar Vinay Singh Head of Department 1404320057 (III year) Department of Electrical Engineering Electrical Engineering
  2. 2. CONTENTS  Introduction  Present Electricity Grid  Comparison b/w Smart grid and Exsisting Grid  Working of Smart Grid  Advantages  Challenges  India’s Smart Grid Project  Conclusion
  3. 3. INTRODUCTION  Smart grid is a combination of hardware management and reporting software in order to built a intelligent communication infrastructure.  Integrates Information and communication technology (ICT) to the power system for :-  Increased reliability  More security  Better efficiency  Reduced environmental impacts
  4. 4. PRESENT ELECTRICITY GRID
  5. 5. COMPARISON  EXSISTING GRID  ELECTROMECHANICAL  ONE -WAY COMMUNICATION  CENTRALIZED GENERATION  FEW SENSORS  MANUAL MONITORING  MANUAL RESTORATION  FAILURES AND BLACKOUTS  LIMITED CONTROL  SMART GRID  DIGITAL  TWO-WAY COMMUNICATION  DISTRIBUTED GENERATION  SENSORS THROUGHOUT  SELF MONITORING  SELF HEALING  ADAPTIVE AND ISLANDING  PERSASIVE CONTROL
  6. 6. WORKING OF SMART GRID  Integration of all sources of energy mainly renewable  Continuous monitoring and feedback from network  Helps in fault prevention  Establish a two way communication  Reduces the stress on existing infrastructure  Reduces and shifts the peak demand  Conserve energy during transmission and distribution  Uses better technologies
  7. 7. ENERGY CONSERVATION TECHNIQUES IN TRANSFORMER  IMPROVEMENT IN DESIGN AND MATERIAL OF TRANSFORMER  By using energy efficient transformer.  By using amorphous transformer
  8. 8. ENERGY CONSERVATION DURING TRANSMISSION  BY REDUCING RESISTANCE  BY CONTROLLING VOLTAGE LEVELS BY REDUCING RESISTANCE BY CONTROLLING VOLTAGE LEVELS ENERGY CONSERVATION DURING DISTRIBUTION  BALANCING OF PHASE LOADS  POWER FACTOR IMPROVEMENTS WER FACTOR IMPROVEMENT
  9. 9. ADVANCED TRANSMISSION SYSTEM  PMUs  WAMs  FACTs  SCADA  FLISR  Power electronics  Islanding concept ADVANCED DISTRIBUTION SYSTEM
  10. 10. PHASOR MEASUREMENT UNIT  It’s (PMU) a device which measures the electrical waves on an electricity grid using a common time source for synchronization.  Works on the concept of synchro phasor technique.
  11. 11. FLEXIBLE AC TRANSMISSION SYSTEM  Voltage control  System stability  Controls real and reactive power flow  High speed response
  12. 12. INTRODUCTION TO SCADA  Supervisory control and data acquisition (SCADA)  The SCADA system in the control room is able to make these automated decisions in real-time by running algorithms based on the data it receives and adjustments to optimize voltages and self-heal any disruption issues.
  13. 13. SMART METERS  Uses a secure national communication network (called the DCC) to automatically and wirelessly send your actual energy usage to your supplier  More accurate bills  Better understanding of your usage  Innovative energy tariffs
  14. 14. ADVANTAGES  Reduces carbon foot prints  Increased capacity to fulfil demand  Improves distribution management  Self healing capability  Automated control for distribution  Increased efficiency  Sustainability  New types of loads such as EVs
  15. 15. CHALLENGES  Lack of awareness  Security  Opposition and concerns  High Investment / Cost Factor  Meters can easily be hacked  Utilities can increase/decrease demand of power
  16. 16. INDIA’S ELECTRICITY NEEDS  DEMAND – 2,10,000 MW (CENTRAL ENERGY AUTHORITY MOP)  PRODUCTION- 1,82,000 MW  INSTALLED CAPACITY - 2,25,000 MW  DEFICIT- 10.2%
  17. 17. INDIA’S SMART GRID PILOT PROJECTS
  18. 18. CONCLUSION  It would go on a long way in solving present energy issues.  Has positive environmental impact  Has long term economic outcome  Drawbacks in short term like lack of funding  Problems of privacy  Lack of public support initially
