Losing Control of your Network? Try Resilience Theory

1 code implementation28 Jun 2023 Jean-Baptiste Bouvier, Sai Pushpak Nandanoori, Melkior Ornik

To assess system vulnerability, we establish resilience conditions for networks with a subsystem enduring a loss of control authority over some of its actuators.

Data-driven Stabilization of Discrete-time Control-affine Nonlinear Systems: A Koopman Operator Approach

no code implementations26 Mar 2022 Subhrajit Sinha, Sai Pushpak Nandanoori, Jan Drgona, Draguna Vrabie

In recent years data-driven analysis of dynamical systems has attracted a lot of attention and transfer operator techniques, namely, Perron-Frobenius and Koopman operators are being used almost ubiquitously.

Graph Neural Network and Koopman Models for Learning Networked Dynamics: A Comparative Study on Power Grid Transients Prediction

no code implementations16 Feb 2022 Sai Pushpak Nandanoori, Sheng Guan, Soumya Kundu, Seemita Pal, Khushbu Agarwal, Yinghui Wu, Sutanay Choudhury

In particular, accurate and timely prediction of the (electro-mechanical) transient dynamic trajectories of the power grid is necessary for early detection of any instability and prevention of catastrophic failures.

Sparse Control Synthesis for Uncertain Responsive Loads with Stochastic Stability Guarantees

no code implementations27 Jun 2021 Sai Pushpak Nandanoori, Soumya Kundu, Jianming Lian, Umesh Vaidya, Draguna Vrabie, Karanjit Kalsi

Detailed numerical studies are carried out on IEEE 39-bus system to demonstrate the closed-loop stochastic stabilizing performance of the sparse controllers in enhancing frequency response under load uncertainties; as well as illustrate the fundamental trade-off between the allowable uncertainties and optimal control efforts.

Stochastic Virtual Battery Modeling of Uncertain Electrical Loads Using Variational Autoencoder

no code implementations18 Mar 2020 Indrasis Chakraborty, Sai Pushpak Nandanoori, Soumya Kundu, Karanjit Kalsi

Effective utilization of flexible loads for grid services, while satisfying end-user preferences and constraints, requires an accurate estimation of the aggregated predictive flexibility offered by the electrical loads.
