Title: Modeling and Co-Simulation in Cyber-Physical Power Systems

Abstract: With the advancement of communication systems and renewable power generation, modern electric power systems are undergoing significant upgrades to become an integrated cyber-physical system. This research work explores the modeling and co-simulation technologies for renewable energy integration and system security enhancement in an integrated cyber-physical system testbed. In particular, this work studies the integration of differential algebraic equation (DAE)-based dynamic power simulation with communication network and data-driven applications. This presentation first introduces a communication network-in-the-loop simulation architecture for mimicking the real-world systems with simulated phasor measurement unit (PMU) data streaming, energy management and measurement-based control, all of which are developed as an open source software suite for the CURENT Large-scale Testbed (LTB). In order to distribute physically coupled devices into multiple software simulations, this paper proposes a data broker setup based on a distributed messaging environment to achieve low-latency data streaming. Case studies verified the data broker setup for low-latency sensing and actuation as well as the communication emulation setup for the desired network latency. The second part of the presentation describes a symbolic framework to simplify the modeling and simulation of DAE-based power system devices. The framework is designed with a goal of making modeling as simple as typing equations and simulation as fast as crafted code. Design philosophy and implementation details are given as an example of a general-purpose symbolic library tailored for power system transient simulation. The framework is validated with power flow calculation and transient simulation with classical generator model.

Bio: Hantao Cui is a Research Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of Tennessee. He is the technical lead of the CURENT Large-Scale Testbed (LTB). He earned his Ph.D. degree in Electrical Engineering from the University of Tennessee in 2018 focusing on power system simulation.

Dr. Cui has co-authored over 20 referred publications. His research interest includes large-scale system simulation and control, cyber-physical system simulation, and high-performance computing. He is the author of several open-source packages, including Andes [1], a power system dynamic simulator written in Python, and LTBNet [2], a communication network emulator for wide-area power system data streaming.

Presenter: Dr. Kevin Tomsovic, CURENT Director

Title: Site Visit Report Review and Open Discussion about the state of the Center

Abstract: Dr. Tomsovic will discuss the Site Visit Report and give an update about the state of the Center and then open the floor for questions. This is an "all-hands" meeting and the everyone in CURENT (faculty, staff and students at all four schools) is expected to attend.

Bio: Dr. Tomsovic is the Director of CURENT and the CTI Professor in the Department of Electrical Engineering & Computer Science at the University of Tennessee. He is also an IEEE Fellow. He received his B.S. in Electrical Engineering at Michigan Technological University in 1982, and he received his M.S. and Ph.D. degrees in Electrical Engineering from University of Washington in 1984 and 1987, respectively. He previously was a professor at Washington State University. Dr. Tomsovic’s areas of interest include intelligent systems and optimization methodologies applied to various power system problems, including distribution system design, electricity market analysis, equipment diagnostics and maintenance, operation of dispersed energy resources, production scheduling, and stabilization control.
