CONCLUSION
WHAT IS SMART GRID?
• Modernization of grid & digitalization.
• Two way communication & Prevention of blackouts.
• consumers and utility companies alike have tools to
manage, monitor and respond to energy issues.
• Combination of renewable energy sources.
Cntd…
Adding sensing, embedded processing and digital
communications makes the grid:
Self healing
Interactive
Optimized
Secure
Predictable
Distributive
NEED FOR A SMART GRID
Conventional grid has electromechanical arrangements ,which are highly inefficients .
False tripping & Frequent power failure.
Energy demand is increasing at a faster rate than energy supply because of the increase in population.
So no of grids increase to feed the demand.
GREEN HOUSE GASES ARE INCREASING DUE TO INCREASE IN FOSSIL FUEL CONSUMPTION
ENERGY PRODUCTION OF
INDIA
ENERGY PRODUCTION BY CHINA
WHAT SHOULD THE SMART GRID CAN DO WHICH IS NOT BE POSSIBLE FOR CONVENTIONAL GRID
Automatic fault restoration by using sensors in transformers & transmission lines.
No headache to call lineman to repair or reroute the electricity from grid.
The consumer can able to know his energy consumption by viewing smart meter in real-time.
COMPARISION

Electromechanical Digital
One way communication Two way communication
Centralized Generation Distributed Generation
Few Sensors Sensors Throughout
Manual monitoring Self monitoring
Manual Restoration Self Healing
Failures & Blackouts are possible No Blackouts
MAJOR COMPONENT OF SMART GRID
SENSING & MEASUREMENT
Its easy to cut our electricity bills if We know…
Exactly how much electricity We are using.
How much it is costing us in rupee per hour
It can easily known from SMART METER.
CONCEPT OF SMART METER
o AUTOMATED METER INFRASTRUCTURE(AMI):
REMOTE READING SYSTEM
ANYTIME VIEWING ENERGY CONSUMPTION
REAL TIME CONSUMPTION
CARRY OUT CUSTOMER ORIENTED SERVICES.
SMART METER:
•MUTUAL BENEFITS FOR UTILITY & CONSUMER.
•FEATURES:
•COMMUNICATION
•SMART CONNECT/DISCONNECT
•OPTIMISED POWER FLOW
•ENERGY AWARENESS
APPLICATION(PLUGIN ELECTRIC VEHICLE):
NOT CHARGING WHEN LOAD DEMAND IS MORE
OPTIMALLY CHARGED AT LOW PEAK & AT PEAK WIND POWER
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 & REQUIRES HIGH COST OF INSTALLATION.
SMART GRID IS COMPUTER BASED IF IT IS HACKED THEN WORST THING WILL HAPPEN.
MOST RENEWABLEENERGY SOURCES ARE INTERMITTENT & NOT RELIABLE.
VARIOUS IMPACTS• GLOBAL EFFECT:
IN G-20 CONFERENCE DEMAND MANAGEMENT & ENERGY , ENVIRONMENT
PROTECTION WAS MAJOR ISSUE.TO REDUCE IT SMART GRID WILL BE EFFECTIVE.
• ENVIRONMENT IMPACT:
REDUCE GREEN HOUSE GASES
• ECONOMIC IMPACT:
PREVENTS BLACKOUTS AS PARTICIPATION OF CONSUMERS
• SOCIAL IMPACT:
REDUCE ELECTRIC BILL BY TRANSPARENT OPERATION IN AUTOMATED WAY
SO IT IS CUSTOMER FRIENDLY & SOCIEO-ECONOMIC.
IT WORKS WITHOUT
SMARTMETER.
IN COMBINATION WITH POWER
METER A PERSON CAN
KNOW REAL TIME ENERGY
CONSUMPTION IN SMART PHONE
BY USING IGOOGLE.
CASE STUDY(PILOT PROJECTS BY POWER GRID):
Pondicherry Smart Grid Pilot Project :
POWERGRID has taken a pioneering initiative to develop Smart Grid Pilot
Project at Pondecherry through collaborative efforts jointly with Electricity
Departments, Govt. of Pondecherry for demonstration of efficacy.
More than 50 organization has participated with POWERGRID for this unique
initative.
Four pilot sites: (North Delhi, Bangalore, Gujurat, Maharastra)
BESCOM Project: Bangalore – Integratation of renewable and
distributed energy resources to the grid.
KEPCO PROJECT IN KERALA: $10b initiatives for smart grid.
FUTURE SCOPE:
Our honorable prime minister of INDIA SHRI NARENDRA MODI initiated ‘DIGITAL INDIA ‘scheme where some cities will be converted into smart cities where smart grid will be implemented to materialize the smart city into reality.
It is risky because of financial developments and regulations.
But in the long run, attitudes will change, wide spread usage of the smart grid from every business to every home just like the internet.
CONCLUSION:
By using smart grid technology energy can be utilized to the maximum and would not be wasted.
This technology also helps to save earth from the global warming.
It refers to the modernized version of the earlier traditional method of energy supply.
