Smart Grids overview

Smart Grid is a rather new concept that includes aspects of energy generation, transmission, and distribution and aims for a more reliable service, higher efficiency, more security, two-way utility-user communications, and promotion of green energy among other goals. Smart Grid has been mainly associated with remote metering, which was later called AMR (automatic meter reading). The activities of AMR were encompassed within those of a broader field that was eventually called AMI (advanced metering infrastructure). Clearly, the metering system is one of the major elements of the Smart Grid but certainly is not the only one. Many elements are included in the overall field of Smart Grids. Those pertaining to distribution systems and in particular to the automation of distribution systems (or distribution automation) will be considered.
