A LASSO-Inspired Approach for Localizing Power System Infeasibility
Shimiao Li, Amritanshu Pandey, Aayushya Agarwal +2
A method is proposed to identify and localize the cause of network collapse with augmented power flow analysis for a grid model with insufficient resources. Owing to heavy network…
Improving Voltage Profile of the Nigerian Power Grid
Amritanshu Pandey, Aayushya Agarwal, Marko Jereminov +3
Extreme voltages at the system nodes are one of the primary causes for total and partial collapse of the Nigerian grid. In this paper, we develop a framework to re-dispatch the vol…
Robust Sequential Steady-State Analysis of Cascading Outages
Amritanshu Pandey, Aayushya Agarwal, Marko Jereminov +3
Simulating potential cascading failures can be useful for avoiding or mitigating such events. Currently, existing steady-state analysis tools are ill-suited for simulating cascadin…
Continuously Differentiable Analytical Models for Implicit Control within Power Flow
Aayushya Agarwal, Amritanshu Pandey, Marko Jereminov +1
Achieving robust and scalable convergence for simulation of realistic power flow cases can be challenging. One specific issue relates to the disconnected solution space that is cre…
