Beyond Uptime: Actionable Performance Metrics for EV Charging Site Operators
Brandon D'Agostino, Jimmy Chen, Ram Rajagopal
The transition to electric vehicles (EVs) depends heavily on the reliability of charging infrastructure, yet approximately 1 in 5 drivers report being unable to charge during stati…
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…
