Arturo Bretas

Manager

Biography

Dr. Bretas is currently Sandia’s Manager for the Electric Grid Security and Communications Department. Dr. Bretas is also Sandia’s Manager for the Secure Grid and Communications (SG&C) program. He is a Research Professor with the Université Grenoble Alpes and a Courtesy Full Professor with the University of Florida.

Dr. Bretas supports a variety of projects related to the development of models, processes and tools for the Electric Energy Infrastructure Security, through Grid Control and Energy Storage. Towards achieving these goals, Dr. Bretas current research lies on the general theme of Distributed Wide-Area Measurement Systems Applications in Cyber-Physical Systems (CPS).

Dr. Bretas has worked as a PI/Co-PI on many R&D projects with the Power Industry. These projects concern, for example, CPS Cybersecurity, Artificial Intelligence and Machine Learning, Distributed Optimization and Control, Power System Stability and Real-Time Monitoring, Distribution Systems Reliability Optimization and Expansion Planning under Uncertain Operation Scenarios.

Dr. Bretas has published many papers on peer-reviewed conferences and journals, as well as a textbook on Cyber-Physical Power Systems State Estimation.
