The Role of Power Electronics in the Future Smart Grid


ECE at the University of Utah presents:

"The Role of Power Electronics in the Future Smart Grid"

Abstract:
The future smart electric grid needs not only smart meters but also smart transmission and distribution technologies. Power electronics will play an important role in the future smart transmission by enhancing the transmission capacity, reliability, and security. Currently, transmission systems are becoming increasingly stressed because of growing demand and because of restrictions on building new lines. However, most high voltage transmission systems are operating below their thermal ratings due to such constraints as stability limits.
