Data-Driven Operator Theoretic Methods for Global Phase Space Learning
Sai Pushpak Nandanoori, Subhrajit Sinha, Enoch Yeung
In this work, we propose to apply the recently developed Koopman operator techniques to explore the global phase space of a nonlinear system from time-series data. In particular, w…
Online Learning of Dynamical Systems: An Operator Theoretic Approach
Subhrajit Sinha, Sai Pushpak Nandanoori, Enoch Yeung
In this paper, we provide an algorithm for online computation of Koopman operator in real-time using streaming data. In recent years, there has been an increased interest in data-d…
Distribution System State Estimation in the Presence of High Solar Penetration
Thiagarajan Ramachandran, Andrew Reiman, Sai Pushpak Nandanoori +2
Low-to-medium voltage distribution networks are experiencing rising levels of distributed energy resources, including renewable generation, along with improved sensing, communicati…
Distributed Barrier Certificates for Safe Operation of Inverter-Based Microgrids
Soumya Kundu, Sijia Geng, Sai Pushpak Nandanoori +2
Inverter-interfaced microgrids differ from the traditional power systems due to their lack of inertia. Vanishing timescale separation between voltage and frequency dynamics makes i…
Identifying Parameter Space for Robust Stability in Nonlinear Networks: A Microgrid Application
Soumya Kundu, Wei Du, Sai Pushpak Nandanoori +2
As modern engineering systems grow in complexity, attitudes toward a modular design approach become increasingly more favorable. A key challenge to a modular design approach is the…
Identification and Validation of Virtual Battery Model for Heterogeneous Devices
Sai Pushpak Nandanoori, Indrasis Chakraborty, Thiagarajan Ramachandran +1
The potential of distributed energy resources in providing grid services can be maximized with the recent advancements in demand side control. Effective utilization of this control…
