The Design of Sensor Networks for Detection of Faults in Smart Power Grids

Professor Demetrios Kazakos
Texas Southern University


Abstract: The development of secure and dependable Smart Grids in Power Systems is an important design goal. The design of a dedicated sensor network that will monitor the secure and dependable, failure resistant, operation of a Smart Grid is a major objective of our research in such systems. The main thrust of our effort is to advance the use of statistical methodology to model the failure of a link or group of links or of a subsystem of a Smart Grid. We propose and study methods for failure detection in a Smart Grid by viewing such failures as the cause creating abrupt changes in the traffic patterns of the power flow. Such approaches have been effective in monitoring the reliability of Communication Networks. In our current work, we expand the same approach for monitoring the secure and dependable operation of Smart Power Grids. The main idea is that a sudden fault of a link, groups of links or of a subsystem will cause an abrupt change in the energy or current flow patterns. In this talk we discuss the use and advances of the novel approach of using statistical tools of decentralized fastest change detection as a building tool of a theoretical and practically implementable change detection and an associated fault detection system. There is a need to advance the state of the art, making the current approaches more sophisticated and flexible to respond to changing, dynamic failure patterns. It is expected that the resulting algorithms and monitoring sensor network systems will improve the reliability and dependability of Smart Power Grids. This research has been conducted at Texas Southern University during the past 3-4 years.
