INTRODUCTION

Utilization of power increased dayby day due to large powerutilization.

The power distribution in hugecomputing environment need tobe control.

SMART GRIDS

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

What Smart Grids really mean Cost Implications*

More choices

Includes renewables

Better quality and service

Greater resiliency / robustness

Increased efficiency and asset utilization

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

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

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 GoIBlending 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

Thinking of the Future…We need Smart GridsBusiness 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…

CONCLUSION

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