Tutorial: Grid-Following Inverter for Electrical Power Grid
Muhammad Hamza Ali, Amritanshu Pandey
The growing use of inverter-based resources in modern power systems has made grid-following inverters a central topic in power-system modeling, control, and simulation. Despite the…
Frequency-Aware Sparse Optimization for Diagnosing Grid Instabilities and Collapses
Swadesh Vhakta, Denis Osipov, Reetam Sen Biswas +3
This paper aims to proactively diagnose and manage frequency instability risks from a steady-state perspective, without the need for derivative-dependent transient modeling. Specif…
Large-scale Grid Optimization: The Workhorse of Future Grid Computations
Amritanshu Pandey, Mads Almassalkhi, Sam Chevalier
Purpose: The computation methods for modeling, controlling and optimizing the transforming grid are evolving rapidly. We review and systemize knowledge for a special class of compu…
Towards Practical Physics-Informed ML Design and Evaluation for Power Grid
Shimiao Li, Amritanshu Pandey, Larry Pileggi
When applied to a real-world safety critical system like the power grid, general machine learning methods suffer from expensive training, non-physical solutions, and limited interp…
Circuit-theoretic Line Outage Distribution Factor
Shimiao Li, Amritanshu Pandey, Larry Pileggi
This work presents the design of AC line outage distribution factor created from the circuit-theoretic power flow models. Experiment results are shown to demonstrate its efficacy i…
Two-Stage Homotopy Method to Incorporate Discrete Control Variables into AC-OPF
Timothy McNamara, Amritanshu Pandey, Aayushya Agarwal +1
Alternating-Current Optimal Power Flow (AC-OPF) is an optimization problem critical for planning and operating the power grid. The problem is traditionally formulated using only co…
