Large-Scale Network Utility Maximization via GPU-Accelerated Proximal Message Passing
Akshay Sreekumar, Anthony Degleris, Ram Rajagopal
We present a GPU-accelerated proximal message passing algorithm for large-scale network utility maximization (NUM). NUM is a fundamental problem in resource allocation, where resou…
GPU Accelerated Security Constrained Optimal Power Flow
Anthony Degleris, Abbas El Gamal, Ram Rajagopal
We propose a GPU accelerated proximal message passing algorithm for solving contingency-constrained DC optimal power flow problems (OPF). We consider a highly general formulation o…
Scalable and Interactive Electricity Grid Expansion Planning
Anthony Degleris, Abbas El Gamal, Ram Rajagopal
Large scale grid expansion planning studies are essential to rapidly and efficiently decarbonizing the electricity sector. These studies help policy makers and grid participants un…
Fast Grid Emissions Sensitivities using Parallel Decentralized Implicit Differentiation
Anthony Degleris, Lucas Fuentes Valenzuela, Ram Rajagopal +2
Marginal emissions rates -- the sensitivity of carbon emissions to electricity demand -- are important for evaluating the impact of emissions mitigation measures. Like locational m…
Gradient Methods for Scalable Multi-value Electricity Network Expansion Planning
Anthony Degleris, Abbas El Gamal, Ram Rajagopal
We consider multi-value expansion planning (MEP), a general bilevel optimization model in which a planner optimizes arbitrary functions of the dispatch outcome in the presence of a…
Equitable dynamic electricity pricing via implicitly constrained dual and subgradient methods
Emmanuel Balogun, Sonia Martin, Anthony Degleris +1
Coordination of distributed energy resources is critical for electricity grid management. Although nodal pricing schemes can mitigate congestion and voltage deviations, the resulti…
Dynamic locational marginal emissions via implicit differentiation
Lucas Fuentes Valenzuela, Anthony Degleris, Abbas El Gamal +2
Locational marginal emissions rates (LMEs) estimate the rate of change in emissions due to a small change in demand in a transmission network, and are an important metric for asses…
A Provably Correct and Robust Algorithm for Convolutive Nonnegative Matrix Factorization
Anthony Degleris, Nicolas Gillis
In this paper, we propose a provably correct algorithm for convolutive nonnegative matrix factorization (CNMF) under separability assumptions. CNMF is a convolutive variant of nonn…
