Smart grid
- 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. 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. 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
- 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. 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. ENERGY CONSERVATION TECHNIQUES IN TRANSFORMER IMPROVEMENT IN DESIGN AND MATERIAL OF TRANSFORMER By using energy efficient transformer. By using amorphous transformer
- 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. ADVANCED TRANSMISSION SYSTEM PMUs WAMs FACTs SCADA FLISR Power electronics Islanding concept ADVANCED DISTRIBUTION SYSTEM
- 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. FLEXIBLE AC TRANSMISSION SYSTEM Voltage control System stability Controls real and reactive power flow High speed response
- 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. 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. 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. 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. 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. INDIA’S SMART GRID PILOT PROJECTS
- 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
