A Smart Grid is an advanced electrical power system that uses digital communication, automation, and information technology to generate, transmit, distribute, and consume electricity efficiently, reliably, and securely.
So a Smart Grid is an electricity network that uses smart technologies to:
- Monitor power flow in real time
- Detect faults automatically
- Improve efficiency and reliability
- Integrate renewable energy sources
Technologies Used in Smart Grid
1️⃣ Advanced Metering Infrastructure (AMI)
- Uses smart meters
- Enables two-way communication between consumer and utility
- Helps in real-time billing and energy monitoring
2️⃣ Communication Technology
- Fiber optics, wireless networks, and power line communication
- Ensures fast and secure data transfer
3️⃣ Supervisory Control and Data Acquisition (SCADA)
- Monitors and controls substations remotely
- Helps in quick fault detection and restoration
4️⃣ Distributed Generation (DG)
- Integration of renewable sources like:
- Solar PV
- Wind energy
- Micro-turbines
5️⃣ Energy Storage Systems
- Batteries, flywheels, supercapacitors
- Stores excess energy and supplies during peak load
Difference Between Traditional (Conventional) Grid and Smart Grid
| Feature | Traditional Grid | Smart Grid |
|---|---|---|
