1. Smart Grid – Fault Detection & Demand Response Presented by: Sirajun Nisha S Roll No: 23E156 Department of EEE

2. Introduction The Smart Grid uses digital communication, sensors, and automation. • It improves efficiency, reliability, and sustainability of the power system. • Enables two-way communication between utilities and consumers.

3. Key Features of Smart Grid • Real-time monitoring • Two-way communication • Integration of renewable energy • Automated control • Fault detection & self-healing • Demand-side management

4. Smart Grid Architecture • Generation: Conventional + renewable sources • Transmission & Distribution: Equipped with sensors and PMUs • Communication Layer: IoT, SCADA, cloud networks • Control Center: AI & analytics for decision-making • Consumers: Smart meters and automated loads

5. Fault Detection in Smart Grid • Faults include short-circuits, line breaks, overloads, and failures. • Detected using sensors, PMUs, and AI algorithms. • System isolates faulty sections and reroutes power. • Enables faster fault recovery and self-healing.

6. Example: Fault Detection Process 1. Fault occurs in transmission line. 2. Sensors detect abnormal voltage/current. 3. Data sent to control center. 4. Faulty section isolated automatically. 5. Remaining system continues operation.

7. Demand Response (DR) • Adjusting electricity usage based on supply and demand. • Helps balance load and reduce peak demand. • Types: - Incentive-Based DR: Rewards for reducing load. - Price-Based DR: Variable pricing encourages off-peak usage.

8. Example: Demand Response • During peak hours, smart meters delay appliance operation. • Consumers receive rewards for saving power. • Prevents overload and reduces cost. • Increases grid efficiency.

9. Integration of Fault Detection & Demand Response • Fault detection ensures reliability. • Demand response ensures load balance. • Together they enable a stable, efficient, and resilient grid.

10. Benefits of Smart Grid • Faster fault recovery • Reduced blackouts • Efficient energy usage • Integration of renewable energy • Lower operational cost

11. Future Scope • AI-driven predictive fault detection • IoT-based automated demand response • Blockchain for secure energy transactions • 100% renewable energy integration

12. Conclusion Smart grids make power systems intelligent and self-healing. Fault detection improves reliability, and demand response enhances efficiency. Together, they build a sustainable energy future. Thank you!
