The smart grid contains:
A power system layer
A control layer
A communication layer
A security layer
An application layer
These layers show organizations can develop a smart grid. The power system layer refers to power generation, distribution, customer systems, and transmission.
The control layer enables smart grid management functions, monitoring, and control, while the communication layer allows two-way communications in the grid.
The security layer provides integrity, data confidentiality, availability, and authentication, while the application layer delivers smart grid applications to customers.
