Title: Mathematical Programming Methods for Control and Optimization of Power Systems
Location: Nedderman Hall Room 106
Time: 1:15pm – 2:15pm

Abstract: This talk is concerned with the development of efficient computational methods for the design, operation and control of power systems. Due to difficulties such as the nonlinearity induced by laws of physics and binary parameters, several power system optimization problems cannot be solved based on a full model and have remained open for decades. Real-world approaches involve inherited approximations and heuristics, based on linearization and local search algorithms, that are believed to be costly and jeopardize the operation of the grid. We introduce a variety of graph-theoretic and penalized optimization techniques that facilitate performing fundamental, yet challenging optimization tasks such as the optimal power flow, state estimation and security constraint unit commitment. A novel method will be discussed for the classical problem of designing distributed controllers for stochastic systems with applications to renewable energy. Lastly, a distributed numerical algorithm with low-complex iterations is presented in order to address the need for solving large-scale conic optimization programs for power system applications. The goal is to develop the essential pieces for a powerful optimization and decision-making engine tailored for the modern grid requirements. The proposed techniques are simulated on real-world nationwide electrical systems.

Biographical Sketch: Ramtin Madani is an Assistant Professor with the Department of Electrical Engineering at the University of Texas at Arlington. He received the Ph.D. degree in electrical engineering from Columbia University in 2015 and was a postdoctoral scholar in the Department of Industrial Engineering and Operations Research at University of California, Berkeley in 2016. His research focuses on developing algorithms for optimization, control and design of real-world complex systems such as electric power grids. Ramtin Madani’s work has received the 2016 Best Publication Award in Energy from the Institute for Operations Research and the Management Sciences (INFORMS) Section on Energy, Natural Resources, and the Environment. His recent work has been a best paper finalist for the flagship conference of the Control Systems Society (53rd Annual Conference on Decision and Control).

Dissimilarity Plots: A Visual Exploration Tool for Partitional Clustering


Date:  Monday, February 13, 2017

Time:  1:15 p.m. – 2:15 p.m.

Location:  Nedderman Hall Room 106


Abstract: Cluster analysis tries to uncover structure in data by assigning each object in the data set to a group (called cluster) so that objects from the same cluster are more similar to each other than to objects from other clusters. Exploring the cluster structure and assessing the quality of the cluster solution have been a research topic since the invention of cluster analysis. This is especially important since all popular cluster algorithms produce a clustering even for data without a “cluster” structure. Many visualization techniques to judging the quality of a clustering and to explore the cluster structure were developed, but they all suffer from certain restrictions. For example, dendrograms cannot be used for non-hierarchical partitions, silhouette plots provide only a diagnostic tool without the ability to explore structure, data dimensionality may render projection-based methods less useful, and graph-based representations hide the internal structure of clusters. In this talk we introduce a new visualization technique called dissimilarity plots which is based on solving the combinatorial optimization problem of seriation for (near) optimal cluster and object placement in matrix shading. Dissimilarity plots are not affected by data dimensionality, allow the user to directly judge cluster quality by visually analyzing the micro-structure within clusters, while they make misspecification of the used number of clusters instantly apparent. Dissimilarity plots are implemented in the R extension package seriation.
Biographical Sketch: Dr. Michael Hahsler is assistant professor of Engineering Management, Information, and Systems (EMIS), Lyle School of Engineering, Southern Methodist University (SMU). He also holds a courtesy appointment with the Department of Computer Science and Engineering, and an adjunct appointment with the Department of Clinical Sciences at UT Southwestern Medical Center. He received his Ph.D. in business informatics from the Vienna University of Economics and Business, Austria, where he worked as an assistant professor and core researcher at the Research Institute for Computational Methods. Dr. Hahsler’s research focuses on methods used in the interdisciplinary field of data science including data mining, data visualization, data streams and combinatorial optimization with applications in bioinformatics, healthcare analytics, quantitative marketing, earth sciences and other engineering disciplines. He has published more than 60 papers in peer-reviewed international journals and conference proceedings and has organized several workshops. He also currently serves as editor of the Journal of Statistical Software, the secretary of the INFORMS Data Mining Section and is the principal developer of several popular data mining related extension packages for R, a free software environment for statistical computing and graphics.seminar-series
