The management of transmission and distribution networks which uses robust two-way
communications, advanced sensors, and distributed computers to improve the efficiency,
reliability and safety of power generation, delivery and use. Additionally it can support
services, such as demand response, to consumers. The concept encompasses a wide
range of technologies, such as advanced meter reading, substation automation and
energy management systems. Smart grid development for the most part can use existing
technologies, applying them in new ways to grid operations
