Digital Twins-in-the-Loop: Integrating Measurement, Modeling, and Cyber-Physical Power Systems
Abstract: Through this talk we dive into a Digital Twin (DT) framework that leverages reduced-order models enhanced with data-driven (aka hybrid fidelity DT) techniques for real-time monitoring and control of cyber-physical devices in modern power grids. It discusses how we can create high-fidelity DTs as cyber-physical replicas by merging dynamic modeling with data-driven estimation, ultimately boosting situational awareness and grid stability. The talk also covers the pros and cons of traditional model-driven, data-driven DT, and hybrid fidelity DT approaches. We will take a look at the software stack and integration pipeline necessary for deploying hybrid fidelity DTs in cloud or fog environments. Key challenges in developing DTs that incorporate reduced-order models and observer-based control schemes to capture system interactions and enhance accuracy will be discussed. Additionally, we will explore data synchronization issues for Digital Twins-in-the-Loop (DTiL), along with real-time data imputation and decentralized control methods, demonstrating how we can tackle measurement gaps and network disturbances. Finally, we will showcase results from DT implementations for heat pumps, EV chargers, and solar inverters, highlighting the emerging role of DTiL in reinforcement learning, federated learning, and spatio-temporal frameworks in the future of electrical grids.

Biography:
Dr. Javad Fattahi received his BSc in Electrical Engineering from IUT, Iran, and worked in high-tech European industries before pursuing his graduate study at SUT, Iran in 2009. He received his Ph.D. in 2015 from University of Ottawa, Canada, where he held his postdoctoral and senior research associate positions. He is now an Assistant Professor at the University of Ottawa, Director of the Grid Vue Lab, and Co-Director of SUNLAB. His research interests lie in the areas related to energy equity and inclusion, distributed energy resources (DER), software-defined nanogrids and digital twins, game theory and complex optimization, smart e-mobility, nanogenerators, modular power electronics, and nonlinear systems. His industrial and research experience includes the design and development of power electronic systems, such as e-mobility drive controls, battery chargers, solar inverters, and bidirectional converters.
Dr. Fattahi is a Professional Engineer (P.Eng.) under PEO and EGBC, a member of the Standards Council of Canada (SCC). He is an IEEE Senior Member, and serves as Vice-Chair and chief editor of the IEEE 2030.5 Committee on Smart Grid Interoperability Testing and Verification, Chair of the IEEE P2882 Standards on Short-Circuit and Protection Coordination, and Member of the IEEE 1547.7 Working Group on Distributed Energy Resources Impact Studies.
