Wide area measurement and control using phasor measurement unit in smart grid

A smart Grid uses two way digital communications with advanced sensors to collect and analyze data for transforming the existing electric grid into intelligent, dynamic self-healing, self optimizing transmission and distribution grid. Because critical grid events often require real-time recognition and real time response. A smart grid uses IP-based, open standard, intelligent communication to measure real-time events such as congestion, system stability, equipment performance, outages and demand response events.
