Smart grid - the upcoming concept in electrical engineering

thanx for sharing this

from this, i have understand about its very basic only..
can u please elaborate it??
how the signal is sent from the consumer end and how it vary with load demand of user???
please elaborate it...

CE- voice doing great biggie!

just a few questions.
reliable? really? As 'reliable' as cable TV? Or reliable as the network around here? not always real good.
Reliability is yet to be proven.

How can you have 'better quality' power?
How does digital make it more efficient other than controlling behavior? What about hacking security?

Debugging will be done by the grid? Well, what if the 'grid' is down/ how will debugging be accomplished.

Then lets consider 'controlling'. Who does the controlling? the smart grid manager? Who will determine if used my toaster too much? Most home customers do not get charged for on-peak pricing.

Also, cost will be HUGE. and for cost, doesn't the utility company make money by how much they SELL YOU? the more you waste the more they make!!

and, who will set the protocols and standards? Microsoft, Cisco, google,GE.
Oh, I do not have much faith in that.

Its a relatively good idea but many questions need to be addressed before jumping into this.

Besides, most people i interface with would rather be OFF-GRID

@jj- Your questions are very cogent. The entire principle of smart grid works on redistribution of power. You can check it out on the net if you want.

yup, i know.
it has good intentions.
actually, 12 years ago I was invloved with communication over power lines.

so how much more bandwidth do you think will be needed to integrate all the AC appliances in just one average town?

example:
how will an elctric dryer be controlled to turn off during high-peak and yet not turn off the water well-pump?
internet? power line communication? what will the cost of that implementation be for every appliance.

intelligent consumers and good conservation techniques would make a big difference at much less cost.
