Title: From Automation to Autonomy: Infrastructure for intelligent protection, control, optimization and operations
Abstract: The electric energy system (power grid) is relatively young but already has been transformed several times as technology advances. Digital technologies have initiated a new transformation some forty years ago. A couple of decades ago we experienced the realization that the new technologies can create the smart grid, an integration of old and new assets by sensing, assessing operating conditions, automating protection, control and optimization. Automation by computer/embedded systems is a big part of the smart grid and brought about concerns of security of the underlying cyber-physical system. The evolving complexity and the underlying large scale problem make it necessary to seek approaches beyond automation that is autonomous operation. The goal of autonomous operation of the electric energy system is multi-faceted because of the large scale, multi-physics and multidisciplinary characteristics of the system. In this talk we will discuss efforts of integrating new technologies into a seamless, autonomous and cyber secure infrastructure for protection, control and operation of the electric energy grid. This infrastructure is the basis for accommodating and providing robust solutions to new problems arising from the integration of renewables, increased uncertainty and steeper ramp rates. The system must be self-healing against failures, hidden or visible, and secure and self-healing against malicious cyber-attacks at every level.
We discuss two present activities towards autonomy: (a) resilient, Cyber Secure Centralized Substation Protection (rCSP) and (b) autonomous, adaptive and Secure Distribution Protection (a2SDP). The proposed technologies form the basis for the next generation of Energy Management Systems and Distribution Management systems.
Bio: Sakis (A. P.) Meliopoulos obtained a Diploma in Electrical and Mechanical Engineering from the National Technical University in Athens, Greece in 1972 and a Master in EE (1974) and a Ph.D. degree (1976) from the Georgia Institute of Technology in Atlanta, Georgia, USA. Dr. Meliopoulos’ first professional association was with Western Electric (1971) in Atlanta, Georgia. After receiving a PhD degree in 1976, he joined the faculty of the Georgia Institute of Technology as an Assistant Professor (1976), Associate Professor (1982-88) and full professor (1989-present). In 2006 Dr. Meliopoulos was named the Georgia Power Distinguished Professor. He is actively involved in education and research for improved safety and electromagnetic compatibility of electric power installations, protection and control of power systems and the application of new technology in these areas. Since 1999 he is the Georgia Tech Site Director of PSERC, an NSF I/URC. In 2016-18 he served as the associate director for cyber-physical security of the Georgia Tech Institute for Information Security and Privacy (IISP). Dr. Meliopoulos has pioneered several new analysis and design techniques for bulk power reliability analysis, safety, protection and electromagnetic compatibility of electric power systems. Most well-known is the EPRI transmission reliability program TRELLS (now renamed TransCARE), the GPS-synchronized harmonic state measurement system for transmission systems (first (1993) wide area measurement system on NYPA), the distributed dynamic state estimation method (SuperCalibrator), the setting-less relay, the CYMSA software (Cyber-Physical Modeling and Simulation for Situational Awareness), his invention of the Smart Ground Multimeter, the EPRI grounding analysis programs, the WinIGS (Integrated Grounding System analysis and design), the GEMI (Grounding and ElectroMagnetic Interference) computer code, and the mGrid computer code – a methodology and implementation for precise analysis of multi-wire power systems with distributed energy resources. Dr. Meliopoulos has modernized many power system courses at Georgia Tech, introduced new courses, initiated the power system certificate program for practicing engineers, he co-developed the Master of Science Cybersecurity, Energy Systems degree, and most importantly he has introduced visualization and animation methodologies that dramatically increase the teaching effectiveness of complex power system concepts. Dr. Meliopoulos is a Fellow of the IEEE. He holds three patents, he has published four books, a chapter in the Standard Handbook for Electrical Engineers and over 450 technical papers. He has received a number of awards, including the Sigma Xi Young Faculty award (1981), the outstanding Continuing Education Award, Georgia Institute of Technology (twice 2002 and 2014), the 2017 D. Scott Wills, ECE Distinguished Mentor Award, several of his papers have received the best paper award (IEEE-PES-SC-1984, IEEE-PES-EC-1987, IEEE-CSS-HICSS 2002, PMAPS 2017), he received the 2005 IEEE Richard Kaufman Award and the 2010 George Montefiore international award and the 2013 IEEE-PES Outstanding Power Engineering Educator Award. In 2019 he was awarded the title of Doctor Honoris Causa by his alma matter, the National Technical University of Athens, Greece.
