The document defines and describes smart grid. A smart grid uses information and communication technologies to improve the traditional power grid. It allows two-way communication between utility companies and customers. A smart grid provides benefits like improved reliability, security, efficiency and integration of renewable energy sources. It enables features like self-monitoring, distributed control, and timely decision-making to make the power grid more adaptive and resilient.

2. What is smart grid?

3. What is smart Grid?
• Smart Grid = Electric Grid + ICT
• ICT – Information & Communication Technologies / Tools ICT
– Integrated Communication Technologies
• A smart grid (SG), is also called smart electrical/power grid,
• intelligent grid, intelligrid, future grid, intergrid, or intragrid

6. Smart Grid – Defination
IEEE
Smart grid is a large ‘System of Systems’, where each functional domain
consists of three layers:
(i) the power and energy layer,
(ii) the communication layer, and
(iii) the IT/computer layer.
Layers (ii) and (iii) above are the enabling infrastructure that makes the
existing power and energy infrastructure ‘smarter’

7. Smart Grid – Defination
U. S Department of Energy
A smart grid uses digital technology to improve reliability,
security, and efficiency (both economic and energy) of the
electrical systems from large generation, through the delivery
systems to electricity consumers and a growing a number of
distributed generation and storage resources.

9.  Observability: It enables the status of electricity grid to be
observed accurately and timely by using advanced sensing and
measuring technologies;
 Controllability: It enables the effective control of the power
system by observing the status of the electricitygrid;
 Timely analysis and decision-making: It enables the
improvement of intelligent decision-making process;
 Self-adapting and self-healing: It prevents power disturbance
and breakdown via self-diagnosis and fault location.
 Renewable energy integration: It enables to integrate the
renewable energy such as solar and wind, as well as the
electricity from micro-grid and supports efficient and safe energy
delivery services for electric vehicle, smart home and others.
