Introduction to Smart Grids
We present a high-level overview of today’s electric grids and the communication networks used to monitor and control them. We describe the goals of Smart Grid, including support of clean energy through the large-scale deployment of renewable sources of energy, peak power reduction, grid modernization, and consumer participation in energy management. We discuss how the motivation to meet these goals drives fundamental changes to today’s electric grid.
Accommodating explosive growth in the number of communication endpoints such as smart meters at every consumer location with Advanced Metering Infrastructure (AMI), expansion of Supervisory Control and Data Acquisition (SCADA) beyond substations with distribution automation (DA), and synchrophasor deployment for wide area situational awareness of interconnection of grids will require current communication capabilities of electric grids to be expanded, modernized, and integrated as the Smart Grid evolves. In addition, a large number of new grid operations and functions will be developed – most requiring communication. This chapter ends with an overview of this book.
