A Review Smart Grid Control Technology

The role of smart grid control is discussed based on the goal of smart grid in this paper. The main features of smart grid, the content and main tasks of smart grid control are reviewed, with an analysis of some key technologies such as information technology, power electronics, energy storage and simulation technologies. Information technologies including optical fiber communications, WMAN (Wireless Metropolitan Area Networks), WLAN (Wireless Local Area Network), WPAN (Wireless Personal Area Network), and PLC are the foundation for the dynamic real-time sensing and controlling of power system. Stream media technology, GIS and GPS will also find their uses in future smart grids. Power electronics, which combine the semiconductor device, circuit topologies and system control technologies, will play key roles in the development of renewable generation, power flow control, power system stability control and power quality control. Energy storage is the fundamental strategy for energy balancing and controlling. Potential energy storage techniques for smart grid are discussed in the paper. Simulation and testing technologies will also be developed at the same time with the development of smart grid. Finally, the relationship between the above key technologies and smart grid control and the prospect of power grid in the future are highlighted.
