The smart grid concepts

A smart grid is a next-generation power infrastructure system that is capable of intelligent demand management because information/communication technology is integrated with traditional power grids. Such integration enables suppliers and demanders to exchange information bi-directionally and in real time and consequently allows operators to implement intelligent demand management, connect the smart grid to renewable energy sources, and charge electric vehicles.

Elements that make up a smart grid

A smart grid is made up of smart meters (AMI), energy management system (EMS), energy storage system (ESS), electric car and charging stations, distributive supply, renewable energy, bi-directional information communication technologies, and intelligent distribution/transmission system.
