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…
A Convex Method of Generalized State Estimation using Circuit-theoretic Node-breaker Model
Shimiao Li, Amritanshu Pandey, Larry Pileggi
An accurate and up-to-date topology is critical for situational awareness of a power grid; however, wrong switch statuses due to physical damage, communication error, or cyber-atta…
