“…the smart grid is a data communications network integrated with the power grid that enables power grid operators to collect and analyze data about power generation, transmission, distribution, and consumption—all in near real time. Smart grid communication technology provides predictive information and recommendations to utilities, their suppliers, and their customers on how best to manage power.
To achieve this vision of ubiquitous near–real time information, a transformation of the power grid communications infrastructure is needed, particularly in transmission and distribution substations. While modern data communication has evolved from telephony modems to IP networks, many power utilities are still deploying modem access and serial bus technology to communicate with their substations. The existing supervisory control and data acquisition (SCADA) remote terminal unit (RTU) systems located inside the substation cannot scale and evolve to support next generation intelligence…”
