3. Introduction
• Advancement of traditional grid
• Traditional electrical grid
Energy generation is done in centralized power plants.
Energy distribution is one directional- from power plants to
the consumers
Monitoring and restoration of grid is done manually
Unidirectional communication
• Smart Grid-
Achieve high reliability in power systems
A cyber physical system equipped with sustainable models of energy
production, distribution and usage
4. What is Smart Grid ?
• Smart grid is conceptualized as a planned nationwide network
that uses information technology to deliver electricity
efficiently , reliably and securely.
• Smart grid is also named as-
Electricity with brain
The energy internet
The electro-net
• According to the definition given by NIST , smart grid is – “ a
modernized grid that enables bi-directional flows of energy
and uses two way communication and control capabilities
that will lead to an array of new functionalities and
application.”

6. Benefits of Smart Grid
• Benefits associated with the smart grid include:
More efficient transmission of electricity
Quicker restoration of electricity after power disturbances
Reduced operations and management costs for utilities and
ultimately power cost for consumers
Increased integration of large scale renewable energy
systems
Improved security
• Benefits of consumers-
Updated information on their energy usage in real time
Program the smart devices to run during off peak hours to
lower energy bills
8. Smart Grid Communication
• Components for smart grid communication –
Smart home appliance
Smart meters
Gateways
Data aggregator units (DAUs)
Meter Data Management systems
• Different network associated with smart grid communication
Home area network
Neighbourhood area networks
Wide area networks
Sensors and actuators networks
10. SMART HOME
• Smart homes depend on
Smart meters and home energy
management systems
Smart appliances
Home power generation
• Smart meters
Provides the smart grid interface between consumer and provider
Operate digitally
Allow for automated and complex transfers of information between
consumer-end and the energy service provider
Help to reduce the energy costs of the consumers
Provides information about usage of electricity in different service
areas to the energy service providers.
Smart meter
11. PLUG-IN-EV
• Smart grid have the infrastructure needed to enable the
efficient use of plug-in-electrical vehicles(PEVs)
• Using PEVs-
Reduced dependency on oil
No pollution when running on electricity
• PEVs rely on power plants to charge their batteries
• PEVs get incentives from energy service provider for providing
energy to the grid through discharging
• Energy service providers encourages the consumers to charge
batteries of PEVs in off peak hours
• PEVs also can be used as an energy source in on peak hours.
12. Operation Centre
• Drawbacks of traditional operation centre
Tries to make sure the amount of generated energy is getting used
If the grid voltage drops due to excess energy generation, the grid
becomes unstable
No means to detect oscillation which leads to blackout
Limited information about the energy flow through the grid
• Smart grid –
For monitoring and controlling on the transmission system in smart
grid Phasor measurement unit (PMU) is used
PMU samples the voltage and current with a fixed sample rate
By increasing sampling rate PMU provides the dynamic scenario of
the distribution system
Multiple PMUs form a phasor network , collected information by the
phasor network is analyized by SCADA system
14. Advantages
• Better energy management.
• Proactive management of
electrical network during
emergency situations.
• Better demand supply /
demand response
management.
• Reduce carbon emissions.
Disadvantages
• Present infrastructure is
inadequate and requires
high cost of installation.
• Smart grid is cyber
physical system whose
security is complex task
15. PROJECTS BY POWER GRID
• Pondicherry Smart Grid Pilot Project :
• POWERGRID has taken a pioneering initiative to develop Smart Grid Pilot
• Project at Pondicherry through collaborative efforts jointly with Electricity
Departments, Govt. of Pondicherry for demonstration of efficacy.
• More than 50 organization has participated with POWERGRID for this unique
initiative.
• Four pilot sites: (North Delhi, Bangalore,Gujrat,Maharastra)
• BESCOM Project: Bangalore – Integration of renewable and
distributed energy resources to the grid.
• KEPCO PROJECT IN KERALA: $10b initiatives for smart grid.

17. Conclusion
By using smart grid technology
energy canbe utilized to the maximum
and would not bewasted.
This technology also helpstosaveearth
from the global warming.
It refers to the modernized version of
the earlier traditionalmethod of energy
supply.
