This document provides an overview of smart grids. It discusses how smart grids use digital technology to save energy, reduce costs, and increase reliability by allowing for two-way communication between utilities and customers. Key benefits of smart grids include more choices for consumers and utilities, better integration of renewable energy, improved power quality and customer service, increased grid efficiency and resilience, and greater utilization of system assets. The document also outlines some of the core components and technologies that make up a smart grid system.

3. INTRODUCTION
Utilization of power increased day
by day due to large power
utilization.
The power distribution in huge
computing environment need to
be control.

4. SMART GRIDS
“A smart grid delivers
electricity from suppliers to
consumers using digital
technology to save energy,
reduce cost and increase
reliability.”

5. What Smart Grids really mean
 Cost Implications*

 More choices
 Includes renewables
 Better quality and
service
 Greater resiliency /
robustness
 Increased efficiency
and asset utilization

6.  A Smart Grid is a Transformation of the power system based
on harnessing digital communications and control
 Utilities will be able to:
 Know what power is going where, and when
 Charge “appropriately” for it
 Control the use of (if not flow) power
 Although Advanced Metering Infrastructure (AMI) is
considered to be the basic building block for a Smart Grid,
the Smart Grid is not just AMI!
 The Smart Grid is a much broader set of technologies and
solutions

8. The Future will be Different
 Consumers may become generators
 Possibly with distributed and/or renevables
 IT has improved to the point where even smaller consumers
(residences) can meaningfully participate in utility load control
schemes
 Residences are a major part of the Indian peak
 The future should have ZERO load-shedding (at a feeder level, at
least)
 Discrimination across and within categories of consumers is
present today and may remain
 Let’s do it more intelligently
 Incentivize behavior at the margin
 Provide a minimum assured supply 24/7

9. Buying Peaking Power
Peak power is always more expensive than the
average
 Plants operate at only 500 or 1000 hours per year
 Ignores 15% target spinning reserves, today articulated
as 5% by GoI
Blending such peak power today is what the West
does
 Raises the costs for ALL users for ALL kWh
 KN example – Raises purchase cost for utilities by Rs.
1/kWh!
Alternative – peaking tariff – let those who
contribute to the peak pay for it
 Requires appropriate metering

14. Thinking of the Future…We need
Smart Grids
Business as usual (BAU) will not be sustainable
o Adding supply is necessary but not sufficient – must make
consumption smarter
Consumers must see and behave based on not just their
average costs but their incremental impact on the grid
o This will create a few losers but (hopefully) more
winners
Appliances and consumption will become smarter
o Whirlpool announced that by 2015 ALL their selected
household appliances will be smart grid capable
(worldwide)
o It’s not a question of when, not if…

15. CONCLUSION
Implementation o smart grid will basically
change the way of power utilization in
could computing environment.
