Short biography of the chair: Panayiotis (Panos) Moutis, PhD, is a Systems Scientist at the Scott Institute for Energy Innovation at Carnegie Mellon University (CMU), USA, since Aug. 2018 (Postdoc Electrical & Computer Engineering – ECE, CMU 2016). He served as a Marie Curie fellow with DEPsys SA, Switzerland, in 2018-2020. In 2014 he was awarded a fellowship by Arup, UK (through the University of Greenwich), on the “Research Challenge of Balancing Urban Microgrids in Future Planned Communities”. Between 2007 and 2015, as part of the research group SmartRUE, at the National Technical University of Athens (NTUA), Greece, he contributed to many R&D projects funded by the European Commission. Panos studied at the School of ECE at the NTUA, Greece (Dipl. 2007, PhD 2015). He has published more than 30 papers and contributed to 3 book chapters, while also has over 10 years of experience as a technical consultant on and developer of projects of Renewable Energy Sources and Energy Efficiency. He is the CTO of Proterima Energy Consultants, Greece, and technology advisor to Xeal (ex EVE Energy), USA, an electric vehicle charging platform start-up. He is a senior member of multiple IEEE societies, associated editor in IEEE & IET journal publications, task-group chair in two IEEE standards working groups, Chair of the IEEE Smart Grid Publications Committee, Editor-in-Chief of the “IEEE Smart Grid Newsletter”, and has served as the Editor-in-Chief of the “IEEE Smart Grid Compendium of Journal Publications, vol. 1”.

Abstract: Utilities in the US have been gradually deploying phasor measurement units (PMUs) to monitor synchrophasors at selected parts of their distribution systems. In Europe, distribution system operators are exploring and, in some cases, testing synchronized measurements of their feeders. Most typical use cases of said applications are power quality monitoring, inverse or high power flows, and wildfire detection and mitigation measures. As there is no specific standardization or consensus about the minimum value expected by deploying PMUs at distribution systems, it is important to gather existing experiences, quantify the impact of on-going efforts, define aspirations for potential use-cases and determine a framework for PMU performance. This panels comprises utility, vendor and academic experts on the subject matter, who will offer insights, review on-going initiatives and propose actions for the path forward.

Name: Omid Alizadeh-Mousavi

Organisation: DEPsys SA – Director R&D, Switzerland

Short biography of the chair: Omid Alizadeh-Mousavi received his Ph.D. degree in electrical engineering from the Swiss Federal Institute of Technology, Lausanne, Switzerland, in 2014. From 2014 to 2015, he was a scientist in power and energy systems group, ABB Corporate Research Center in Baden-Dättwil, Switzerland. Since 2016, he has been a research and development director at DEPsys in Puidoux, Switzerland. His research interests are in power systems with particular reference to optimal system operation and planning, and security and risk assessment. He is the author or coauthor of more than 30 scientific papers in peer-reviewed journals and international conferences.

Abstract: Deploying real-time monitoring in distribution grids with sophisticated, cost effective and technically feasible edge computing is imperative to make data-based decisions in systems that traditionally lack visibility. Precise and fast fault identification and localization, accurate power quality monitoring and compliance analysis can be readily enabled by said monitoring.

Title of presentation: Distribution Time-Synchronized Measurements: Sensors and Applications

Abstract: Distribution places unique requirements for time-series systems. Inverter based resources, proximity to loads, and shorter lines result in higher frequency signal content along with smaller signal changes. This presentation will share research in high-speed time-synchronized sensors and associated applications.
