Abstract: This talk presents a method to detect permanent errors in utility data bases related to branch parameters. The method will first be described for systems explicitly containing fully transposed lines and symmetric branch models. It will then be extended to three-phase non-symmetrical mixed-phase power networks. The first method uses output of existing state estimators to enable detection and differentiation between errors in analog measurements and branch model parameters. The main advantages of the method are that it does not require modification of existing state estimators, it is a stand-alone application which can be executed on or offline, does not require any user intervention or a priori selection of a suspect parameter set, and can identify all existing erroneous parameters in a large-scale power system data base while differentiating them from any existing measurement errors. Modal decomposition and compensation methods will be used to extend the method to three-phase systems. The talk will also cover an alternative robust state estimation method which can simultaneously estimate the system states and parameter errors. The talk will provide results obtained by applying the developed techniques to synthetic as well as actual power systems.

Bio:  Ali Abur obtained his B.S. degree from Orta Doğu Teknik niversitesi, Turkey and both his M.S. and Ph.D. degrees from the Ohio State University, Columbus, Ohio. He was a faculty member at Texas A&M University until November 2005 when he joined the faculty of Northeastern University as a Professor and Chair of the Electrical and Computer Engineering Department. His research and educational activities have been in the area of power systems. He is a Fellow of the IEEE for his work on power system state estimation. He co-authored a book and published widely in IEEE journals and conferences.
