Dejan Sobajic

Dejan Sobajic, Ph.D., has over 40 years of experience in the areas of power system operations and planning, wholesale markets operations, control-center technology, operator training and IT design. Most recently, at NYISO, he was responsible for the coordination of investment and demonstration projects proposed by NYS utilities in response to the 2009 American Recovery and Reinvestment Act. NYISO is a present recipient of the DOE Smart Grid Investment Grant.  At EPRI, his responsibilities included strategic planning and marketing of EPRI’s Power Delivery & Power Markets programs. He was also involved in extensive interactions with FERC, NERC, US DHS, US DOE, ETSO and the European Commission. Dr. Sobajic was responsible for key industry initiatives – including the Advanced market design, system-wide implementation of the Common Information Model (CIM) and its extensions for market data (CME), and the Reliability Initiative – an industry-led effort aimed at uncovering root causes of reliability problems of the North American transmission grid. Dr. Sobajic has been invited to provide testimony to the US Congress and FERC. In 1988 he pioneered the use of neural net technology in the field of power system engineering. He designed the unsupervised/supervised learning and supervised clustering neural net paradigms.  In 1990 he designed the first neural net controller for load-frequency regulation using the principle of learning control. He developed and delivered the first tutorial on “Neural Net Applications for the Electric Power Industry”, at FURNAS in Rio de Janeiro in 1989. Dr. Sobajic has edited the first textbook on the subject of use of neurocomputing in power system engineering entitled “Neural Network Computing for the Electric Power Industry”(1993). He is the author/co-author of over 100 technical papers in power system analysis, stability, system operation and markets, control and computational intelligence. He can communicate in English, Russian, German and Serbian language.
