Introduction to Smart Grid:
• Uses information technologies to improve how
electricity travels from power plants to consumers
• Allows consumers to interact with the grid
• Integrates new and improved technologies into the
operation of the grid

6. Introduction to smart grid…
• Smart grid
– Modern electric power-grid infrastructure
– For improving efficiency, reliability and safety
– With integration of renewable and alternative
energy sources
– Through automated control and modern
communication technologies

7. Introduction to smart grid…
• The key factor
– Online power system condition monitoring,
diagnostic, and protection
– Reliable and online information
– Avoid power disturbances and outages due to
equipment failures, capacity limitations, natural
accidents and catastrophes

irradiance, wind speed,
temperature measurement
systems to improve the
predictability of renewable
energy.
– The grid control systems can
dynamically adjust the source
of power supply.

16. WSN in Power system…
• Existing and potential applications of WSNs on
smart grid
