Abstract: Many facets of security in power systems
Security in power systems is truly a cyber-physical concept. A widely accepted physical aspect of it has to do with the ability of a power system to withstand large disturbances, which essentially measures transient stability upon the occurrence of, for example, an equipment fault. A second physical aspect of security has to do with the ability of protection devices to remain restraint when they are not supposed to falsely trip under some disturbances. Insecurity associated with protection false trips has been a main culprit of cascading failures. This talk briefly describes my effort to enhance the physical security by cashing on the entry of modern networked sensors to make real-time decisions on protective control actions. Since this effort amounts to exploiting the computing and communication potentialities of the sensor and protective control networks, the third aspect of security – cyber security becomes highly relevant.
N. Eva Wu obtained her PhD degree in December 1987 from University of Minnesota. She is currently a professor with the ECE department at Binghamton University. Her research interest has been on fault-tolerant control of dynamic systems with a recent focus on mitigation of cascading failures in electric power systems.
