Smart grid technology named as one of the seven technologies that may help change the world, driven by governments and industry, is transforming how electricity is generated, stored, distributed, and consumed. It provides real-time monitoring of transformers and line voltage, data collection and remote control of system elements such as substations, intelligent devices, smart meters, power lines, capacitor banks, feeder switches, fault analyzers and other physical facilities.
The usa department of energy's (doe) smart grid task force defined the smart grid as a future power delivery grid that:
•enables active participation by consumers
•accommodates all generation and storage options
•enables new products, services and markets
•provides power quality for the range of needs in a digital economy
•optimizes asset utilization and operating efficiency
•anticipates and responds to system disturbances in a self-healing manner
•operates resiliently against physical and cyber attacks, and natural disasters
Distribution automation systems are key to providing two-way communication with these elements, as well as to identifying and isolating faults, and restoring service. Ami (advanced metering infrastructure) plays a central role in providing a two-way communication.
