| '''Grid''' usually refers to a [[network]], and should not be taken to imply a particular [[physical]] layout or breadth. Grid may also be used to refer to an entire [[continent]]'s [[electrical]] network, a regional transmission network or may be used to describe a subnetwork such as a local utility's transmission grid or distribution grid. | | '''Grid''' usually refers to a [[network]], and should not be taken to imply a particular [[physical]] layout or breadth.

| The infrastructure system is the [[energy]], [[information]], and [[communication]] infrastructure underlying of the smart grid that supports 1) advanced electricity generation, delivery, and [[consumption]]; 2) advanced [[information]] metering, monitoring, and management; and 3) advanced [[communication]] technologies. In the [[transition]] from the conventional power grid to smart grid, we will replace a [[physical]] infrastructure with a digital one.

− | The management system is the subsystem in ''smart grid'' that provides advanced management and [[control]] services.

Within the advanced infrastructure framework of smart grid, more and more new management services and applications are expected to emerge and [[eventually]] revolutionize consumers' daily lives. | + | The management system is the subsystem in ''smart grid'' that provides advanced management and [[control]] services.

− | The [[protection]] system is the subsystem in smart grid that provides advanced grid reliability [[analysis]], [[failure]] protection, and [[security]] and [[privacy]] protection services. We must note that the advanced [[infrastructure]] used in ''smart grid'' on one hand empowers us to realize more powerful [[mechanisms]] to defend against attacks and handle failures, but on the other hand, opens up many new vulnerabilities. For example,[http://en.wikipedia.org/wiki/NIST NIST] pointed out that the major benefit provided by smart grid, i.e. the ability to get richer [[data]] to and from customer smart meters and other electric devices, is also its Achilles' heel from a [[privacy]] viewpoint. The obvious privacy concern is that the energy use [[information]] stored at the meter acts as an information rich side [[channel]]. This information can be mined and retrieved by interested parties to reveal [[personal]] [[information]] such as individual's [[habits]], [[behaviors]], activities, and even [[beliefs]].[http://en.wikipedia.org/wiki/Grid_%28electricity%29] | + | The [[protection]] system is the subsystem in smart grid that provides advanced grid reliability [[analysis]], [[failure]] protection, and [[security]] and [[privacy]] protection services.
