Small-Signal Dynamics of Lossy Inverter-Based Microgrids for Generalized Droop Controls

no code implementations4 Apr 2024 Abdullah Al Maruf, Anamika Dubey, Sandip Roy

Simulated transient responses of a modified IEEE 9-bus system are presented to validate the theoretical findings which show the effectiveness of generalized droop controls in independently shaping the settling times of the angle and voltage responses of the lossy microgrid system.

Using Demand Response to Improve Power System Small-Signal Stability

no code implementations12 Apr 2023 Mengqi Yao, Sandip Roy, Johanna L. Mathieu

Our results show that shifting the load between buses, can improve a small-signal stability margin.

Graph-Theoretic Analyses and Model Reduction for an Open Jackson Queueing Network

no code implementations10 Feb 2023 Chenyan Zhu, Sandip Roy

A graph-theoretic analysis of the steady-state behavior of an open Jackson queueing network is developed.

Propagation Stability Concepts for Network Synchronization Processes

no code implementations9 Oct 2022 Sandip Roy, Subir Sarker, Mengran Xue

A notion of disturbance propagation stability is defined for dynamical network processes, in terms of decrescence of an input-output energy metric along cutsets away from the disturbance source.

On the Spatial Pattern of Input-Output Metrics for a Network Synchronization Process

no code implementations22 Jul 2022 Subir Sarker, Sandip Roy

A graph-theoretic analysis is undertaken for a compendium of input-output (transfer) metrics of a standard discrete-time linear synchronization model, including lp gains, frequency responses, frequency-band energy, and Markov parameters.

Compressive Representations of Weather Scenes for Strategic Air Traffic Flow Management

no code implementations2 Jul 2021 Sandip Roy

Terse representation of high-dimensional weather scene data is explored, in support of strategic air traffic flow management objectives.

Distinguishing Aerial Intruders from Trajectory Data: A Model-Based Hypothesis-Testing Approach

no code implementations16 May 2021 David Petrizze, Kasra Koorehdavoudi, Mengran Xue, Sandip Roy

The maximum a posteriori probability detector is obtained, and then is simplified to an explicit computation based on two points in the sample autocorrelation of the data.

Compressibility of Network Opinion and Spread States in the Laplacian-Eigenvector Basis

no code implementations28 Mar 2021 Sandip Roy, Mengran Xue

In this study, we explore whether snapshot data from these processes can admit terse representations.

Observability-Blocking Control using Sparser and Regional Feedback for Network Synchronization Processes

no code implementations15 Mar 2021 Abdullah Al Maruf, Sandip Roy

Next, the topological structure of the network is exploited to reduce the number of controllers required for blocking observability; the result is based on blocking observability on the nodes associated with a vertex-cutset separating the actuation and measurement locations.

A Note on Surgical Eigenstructure Assignment via State Feedback

no code implementations5 Oct 2020 Abdullah Al Maruf, Sandip Roy

Assignability of all eigenvalues and a subset of key eigenvectors/generalized eigenvectors of a linear time-invariant system via state feedback is considered.
