Smart Grid
Overview
Our nation’s electric power infrastructure that has served us so well for so long – also known as “the grid” – is rapidly running up against its limitations. Our lights may be on, but systemically, the risks associated with relying on an often overtaxed grid grow in size, scale and complexity every day. From national challenges like power system security to those global in nature such as climate change, our near-term agenda is formidable.

The Smart Grid of our title – represents the longer-term promise of a grid remarkable in its intelligence and impressive in its scope, although it is universally considered to be a decade or more from realization. Yet given how a single “killer application” – e-mail – incited broad,
A smarter grid applies technologies, tools and techniques available now to bring knowledge to power – knowledge capable of making the grid work far more efficiently...

 Ensuring its reliability to degrees never before possible.
 Maintaining its affordability.
 Reinforcing our global competitiveness.
 Fully accommodating renewable and traditional energy sources.
 Potentially reducing our carbon footprint.
 Introducing advancements and efficiencies yet to be envisioned.

The Smart Grid:
A smart grid is basically the transformation of present grid using smart technologies, applications, electronic instruments any many more things.
Comparison of Smart Grid with the present grid:
Intelligent
It is capable of sensing system overloads and rerouting power to prevent potential outage; of working autonomously when conditions require resolution faster than humans can respond…and cooperatively in aligning the goals of utilities and consumers.

Efficient

It is capable of meeting the demand of consumers without affecting infrastructure and securities.
These charging of these cars works on a basic principle of faraday which says that whenever there is a relative motion between a conductor and a magnet then flux changes due to which emf is induced. As we known that hydraulic suspension absorb more potential energy so they are more efficient than spring shock absorbers. Using hydraulic suspension we can charge our battery more than enough. The more the weight of a vehicle the more they will get jerks and more potential energy will be absorbed which means that in these cars weight is directly proportional to car
