Dynamic Monitoring and Decision Systems
for Sustainable Electric Energy Service
A modern electric energy system comprises physical energy sources, a delivery infrastructure and consuming users, as well as its Supervisory Control and Data Acquisition cyber system. The basic premise of this talk is that a physical electric power grid and its cyber system (together forming a “smart grid”) play the key role in matching the characteristics of system users to the objectives of the overall electric energy system. Designing such a system is not easily executed because user objectives often conflict and do not align with the objectives of the overall system (reliability, efficiency, security). Managing these characteristics requires a Dynamic Monitoring and Decision System (DyMonDS) which integrates feedback control, adaptation, learning and data-driven decisions.
This talk presents a DyMonDS framework. The framework accounts for the unique structure of complex electric energy systems and is based on a new general structure-preserving multi-layered dynamic model. While the proposed framework naturally supports user-centric decision making with minimal coordination by the grid operators, the actual complexity of the cyber design is determined by what needs alignment, at what rate, and in which context. Grid control becomes a means of enabling what resources and users need. To show this, we illustrate the basic cyber system complexity for three different types of energy systems (large conventional energy sources distant from large passive users; highly distributed micro-grids; and their hybrid). Using DyMonDS to make electric energy systems in the Azores Islands low cost and clean is provided as an example.
Dr. Marija Ilić holds a joint appointment at Carnegie Mellon as Professor of Electrical & Computer Engineering and Engineering & Public Policy, where she has been a tenured faculty member since October 2002. Her principal fields of interest include electric power systems modeling; design of monitoring, control, and pricing algorithms for electric power systems; normal and emergency control of electric power systems; control of large scale dynamic systems; nonlinear network and systems theory; modeling and control of economic and technical interactions in dynamical systems with applications to competitive energy systems.
Dr. Ilić received her M.Sc. and D.Sc. degrees in Systems Science and Mathematics from Washington University in St. Louis and earned her MEE and Dip. Ing. at the University of Belgrade. She is an IEEE Fellow and an IEEE distinguished lecturer, as well as a recipient of the First Presidential Young Investigator Award for Power Systems. In addition to her academic work, Dr. Ilić is a consultant for the electric power industry and the founder of New Electricity Transmission Software Solution, Inc. (NETSS, Inc.). From September 1999 until March 2001, Dr. Ilić was a Program Director for Control, Networks and Computational Intelligence at the National Science Foundation.
