Smart grid is a form of electricity network utilizing digital technology to improve reliability, optimize asset utilization, and enhance security. It uses integrated communication, power automation, smart meters, sensing and measurement, and advanced components. In Sri Lanka, smart grid implementation includes prepaid electricity metering by Dialog Axiata and solar power monitoring by JLanka. Worldwide, smart grids are used for generation and transmission expansion and reducing emissions. The advantages are reduced costs, failures, theft and carbon footprint while the disadvantages include needing continuous communication networks and being expensive to install.

3. Introduction
What is Smart grid ?
• Smart grid is a form of electricity network utilizing
digital technology.

4. Different type of Technologies
Integrated
communication
For real-time control,
information and data
exchange to optimize
system reliability, asset
utilization, and security
Power system
automation
rapid diagnosis of
and precise solutions
to specific grid
disruptions or
outages

Records consumption
of electric energy and
communicates the
information to the
electricity supplier for
monitoring and billing.
Sensing &
measurement
Core duties are
evaluating congestion
and grid stability
Advanced
Components
Electricity generation
with demand using
multiple identical
generators which can
start, stop and operate
efficiently
