The Integration Of Smart Meters Into Electrical Grids To Ensure Maximum Benefit For Consumers, Generators And Network Operators., Tom Bean, John Mcgrory

Dissertations

The term “smart metering” has been used in many project descriptions and publications produced by utility companies (e.g. gas, water and electricity), conference papers and journal papers, but the true meaning of the term has been fudged. Does smart metering signify rapid recording of data (i.e. data logger) or does it give totals (e.g. maximum, minimum and average), as neither of these are truly “Smart” or “Intelligent” virtues in themselves, or is there some additional role that needs to be explored. This dissertation examines the “smart metering” idiom jointly from energy supplier, grid manager and consumer perspectives and formulates a …
