Smart Grid

A smart grid is an electric power grid that uses digital communications technology and information systems to detect and react to local changes in usage. Smart grids allow for two-way communication between the utility and consumers, enabling more efficient transmission and distribution of electricity.

The goal is to improve reliability, optimise assets, and empower consumers to manage their energy usage. Smart grid technologies are seen as essential for building a modern, sustainable, and resilient power system.

What is a Smart Grid?

A Smart Grid is an electrical grid integrated with automation, communication, and information technologies to monitor and control power flows in real time, identify losses, and enable appropriate actions to reduce losses and incorporate renewable energy through distributed generation.

Features of Smart Grid

• Advanced metering infrastructure: Smart meters enable real-time monitoring of energy consumption and automatic meter readings.
• Distribution management systems: These systems use computer-based remote control, automation, and monitoring to enhance reliability and efficiency.
• Smart appliances: They optimise energy use via demand response.
• Energy storage systems: This helps in grid stabilisation and peak load management.
• Renewable energy integration: Renewables are integrated through forecasting, storage, and demand response.
• Wide area monitoring systems: These systems enhance visualisation and stability.
• Outage management systems
• Electronic billing systems and customer care systems

Measures taken in India to promote Smart Grids

India's Smart Grid Vision aims to transform the Indian power industry into a safe, adaptable, sustainable, and digitally connected ecosystem that offers reliable and quality energy for all with active stakeholder engagement. The Indian government is promoting smart grids through various programs which provide funding and support for state power utilities to invest in smart meters, sensors, automation, analytics, and control systems.

Some of them are listed below:

• National Smart Grid Mission: It was launched in 2015 to accelerate smart grid deployment across India by providing financial support and guidance.
• Smart Meter National Programme: Launched by the Ministry of Power in 2021 to install 250 million smart meters across India by 2025.
• Virtual SMART Grid Knowledge Center: It was launched by POWERGRID and the Power Ministry, and aims to foster innovation, entrepreneurship, and research in smart grid technologies
• Other initiatives: Smart Cities Mission, Green Energy Corridor, PM SAUBHAGYA, etc.
