Guaranteeing Service in Connected Microgrids: Storage Planning and Optimal Power Sharing Policy

no code implementations12 Mar 2024 Arnab Dey, Vivek Khatana, Ankur Mani, Murti V. Salapaka

To address this issue, battery energy sources (BESs) are being increasingly used as a promising solution to counter the uncertainty associated with RES power production.

Causal Structure Recovery of Linear Dynamical Systems: An FFT based Approach

no code implementations5 Sep 2023 Mishfad Shaikh Veedu, James Melbourne, Murti V. Salapaka

We demonstrate that the computational complexity of recovering the causation structure for the vector auto-regressive (VAR) model is $O(Tn^3N^2)$, where $n$ is the number of nodes, $T$ is the number of samples, and $N$ is the largest time-lag in the dependency between entities.

Information Theoretically Optimal Sample Complexity of Learning Dynamical Directed Acyclic Graphs

1 code implementation31 Aug 2023 Mishfad Shaikh Veedu, Deepjyoti Deka, Murti V. Salapaka

In this article, the optimal sample complexity of learning the underlying interactions or dependencies of a Linear Dynamical System (LDS) over a Directed Acyclic Graph (DAG) is studied.

Transactive Framework for Dynamic Energy Storage Allocation for Critical Load Management

no code implementations14 Jan 2021 Arnab Dey, Vivek Khatana, Ankur Mani, Murti V. Salapaka

Although the emerging transactive energy management techniques improve the grid reliability, the inherent uncertainty of RES poses a challenge in meeting the power demand of the critical infrastructure in the microgrid unless sufficient battery energy storage is maintained.

Topology Identification under Spatially Correlated Noise

no code implementations8 Dec 2020 Mishfad Shaikh Veedu, Murti V. Salapaka

It is shown, under the assumption that the correlations are affine in nature, such network of nodal interactions is equivalent to a network with added agents, represented by nodes that are latent, where no corresponding time-series measurements are available; however, here all exogenous excitements are spatially (that is, across agents) uncorrelated.

Topology Learning of Linear Dynamical Systems with Latent Nodes using Matrix Decomposition

no code implementations16 Dec 2019 Mishfad S. V., Harish Doddi, Murti V. Salapaka

It is shown that for a large class of systems, the unique decomposition of imaginary part of the IPSDM of observed nodes, a skew symmetric matrix, into the sparse and the low-rank components is sufficient to identify the moral graph of the observed nodes as well as the Markov Blanket of latent nodes.
