This article is a summary of a larger research project on Smart Grid (SG) and the function of AMI in SG. The poll was taken as part of research on the viability of establishing a Net-Zero neighbourhood in a city in Ontario, Canada. SG is not just one kind of technology but rather an amalgam of several disciplines across engineering, communication, and management. As the backbone of SG, which is in charge of gathering all the data and information from loads and consumers, this article presents AMI technology and its current position. Along with DSM, AMI is in charge of creating control signals and directives to carry out the required control activities. In this work, we provide an overview of SG and its characteristics, clarify the connection between SG and AMI, describe the three primary components of AMI, and address relevant security concerns.
