This document discusses smart grid technology. It defines smart grid as an electric grid that uses information and communication technology to gather data and act on information about supplier and consumer behavior. The key components of a smart grid are smart meters, phasor measurement, information transfer, and distributed generation. A smart grid offers benefits like reduced carbon footprint, improved distribution management, self-healing capabilities, and increased efficiency. Specific ideas presented for a smart grid include a power management app that provides household electricity usage insights and allows selling regenerative power back to the grid.
