The document discusses smart grid technology. It begins with an introduction and then covers related work, components of a smart grid, how it works, features, advantages and disadvantages. A smart grid integrates information and communication technologies with the traditional power grid. It allows two-way communication between utilities and customers. Key components include connectivity networks, smart meters, and sensors. A smart grid provides benefits like reduced losses, automated control, reliability and reduced carbon emissions. However, challenges include the need to augment existing infrastructure and ensuring communication is not interrupted. Overall, smart grids are expected to become more widely used in the future.
