Power Grid Modernization and Smart Grid

What is Power Grid Modernization and Smart Grid?

Power Grid Modernization involves upgrading the existing electricity transmission and distribution infrastructure to enhance its reliability, efficiency, and flexibility. A Smart Grid is an advanced, modernized grid that uses digital communication technology to detect and react to local changes in usage, improving efficiency and reliability, and facilitating the integration of renewable energy.

Historical Background

India's traditional power grid was designed for unidirectional power flow from large, centralized fossil fuel plants. The rapid growth of distributed and intermittent renewable energy sources necessitated a shift towards a more flexible and intelligent grid architecture.
