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.

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.
