The Temporal and Spatial Properties and Uses of Power System Data

Mladen Kezunovic


One distinct phenomenon that characterizes today’s utilities’ practice is “explosion” of data. Different types of power system related data are being recorded in the field or made available from dedicated data tracking systems such as lightning detection, weather forecasting, geographic information, animal migration, etc. Understanding temporal and spatial aspects of such data leads to a variety of new approaches to power system monitoring, control and protection. This lecture discusses the fundamental property of various types of data and defines data integration framework that leads to development of new applications. Examples of on-going projects presented to illustrate how the new framework may be deployed are: a) integration of operational and non-operational data for improved fault and disturbance analysis and b) big data integration for hierarchically coordinated protection.


Dr. Mladen Kezunovic is the Eugene E. Webb Professor at the Department of Electrical and Computer Engineering at Texas A&M University (TAMU). He worked for Westinghouse Electric in the U.S.A. as a Systems Engineer on development of the first all-digital substation during 1979-1980 and for Energoinvest Company in Europe as the Technical Leader for substation automation development during 1980-86. He also spent sabbaticals at EdF’s Research Centre in Clamart, France in 1999/2000 and at the University of Hong Kong in the fall of 2007. He presently servers in several roles: Director of the Smart Grid Center, Deputy Director of NSF I/UCRC Electrical Vehicles: Transportation and Electricity Convergence (EV-TEC), and TAMU’s Site Director of the NSF I/UCRC Power Systems Engineering Research Center (PSerc). Dr. Kezunovic is the President&CEO of XpertPower Associates and served as the Principal Consultant to over 50 utilities and vendors worldwide. Dr. Kezunovic acted as the PI on over 100 research and development projects ranging from implementation of real-time and open-loop digital simulators for relay testing to software solutions for automated analysis of faults and power quality disturbances. His current research activity is related to development of new concepts for substation automation, new approaches to condition-based asset management, and new applications in relaying and control. He published more than 450 journal and conference papers and has given over 100 invited lectures, short courses and seminars worldwide.

Dr. Kezunovic is a Fellow of the IEEE, an IEEE Distinguished Lecturer and a member of CIGRE-Paris. He is a registered Professional Engineer in Texas.
