The current research interests of Dr. Xu are power disturbances defined in a very broad sense. For example, a harmful disturbance is considered as a power quality concern, so his team investigates techniques for power quality assessment, diagnosis and improvement. On the other hand, some disturbances can also be considered as information carriers. Dr. Xu’s group also researches techniques for power system communication, condition monitoring and active protection using naturally occurring or intentionally generated disturbances. All this research work is driven by the vision that power systems (especially power distribution systems) will become "smarter" through the use of the information and communication technologies. Making use of power disturbances in a positive way is a very promising direction to support the smart grid vision.
