Telecommunications networks are at the core of transforming the power grid into the smart grid. The latter, according to the most familiar definition, is the superposition (or integration) of information and communications technologies infrastructure and electric infrastructure to leapfrog the latter from the last century to modern days (https://www.nist.gov/ctl/smart-connected-systems-division/smart-grid-group/smart-grid-framework). Communication network technology was introduced in utilities initially to support the deployment of supervisory control and data acquisition (SCADA) systems. These SCADA systems allowed operations personnel to remotely monitor and control generation, transmission and distribution, power plants, and substation equipment from utility operations centers, enhancing the power grid’s operational efficiency. In addition, communication networks found use in the remote support of automated circuit breakers known as teleprotection systems . More recently, grid communications enabled grid-edge technologies through the Internet of Things (IoT) and synchrophasor-based wide-area measurement systems (WAMSs).
