Abstract: Recent technological advances in protection, control and optimization are enabling a more automated power system. Research efforts are focused on integrating these technologies into a seamless and cyber secure infrastructure for protection, control and operation. 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 secure against malicious cyber-attacks at every level. We discuss the infrastructure at the substation level where we build upon the dynamic state estimation based protection (EBP) and a centralized substation protection integrated with distributed dynamic state estimation and all substation control, operation and optimization functions. All functions are model based: we discuss an automated creation of the models required at each level of a hierarchical control, operation and optimization functions. The substation level system is extended to a subsystem/agent level for control and optimization at subsystems consisting of extended clusters of substations. At subsystem level, the infrastructure enables full state feedback for optimal control. Issues of time latency are addressed. Finally, the concepts are extended to the control center where all the functions that coordinate substations and subsystems are exercised. At each one of the three levels (substation, subsystem, control center), defenses against malicious cyber-attacks are integrated. We will discuss data attacks as well as insertion of malicious commands and the integrated intrusion detection methods. The proposed approach and infrastructure forms the basis for the next generation of Energy 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. 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. 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 and still operational), the distributed dynamic state estimation method (SuperCalibrator), 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 and most importantly he has introduced visualization and animation methodologies that dramatically increase the teaching efficiency of complex power system concepts. Dr. Meliopoulos is a Fellow of the IEEE.

This seminar is offered as a 1 unit seminar course, CEE 272T/EE292T for interested students. The course can be repeated for credit.
