ABSTRACT
This chapter provides an overview of the smart metering and infrastructure (SMI) system and its components and discusses its benefits and relation to the smart grid. It explores the various applications of SMI in support of distribution system planning, analysis, and operations, and introduces the emerging smart meter data analytics with a real implementation example. Smart meters are intelligent, solid-state, programmable devices that can perform many functions beyond energy consumption recordings. By using built-in memories, smart meters can record and store readings at preset intervals and prescheduled times. Most of the smart meters available on the market can also send out a "last gasp" message when loss of power is detected and a "first breath" message when power service is restored. A SMI communication system usually has hierarchical architectures and hybrid communication systems with various technologies.
