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…
A Circuit-Theoretic Approach to State Estimation
Shimiao Li, Amritanshu Pandey, Soummya Kar +1
Traditional state estimation (SE) methods that are based on nonlinear minimization of the sum of localized measurement error functionals are known to suffer from non-convergence an…
SUGAR-R: Robust Online Restoration Platform for SCADA-Absent Grid
Amritanshu Pandey, Aayushya Agrawal, Marko Jereminov +1
Secure and fast grid restoration from a collapsed state is increasingly critical as blackouts are becoming more prevalent around the globe. Generally, the restoration of grid durin…
Implicitly Modeling Frequency Control within Power Flow
Aayushya Agarwal, Amritanshu Pandey, Marko Jereminov +1
In this paper, we extend a circuit-based, current-voltage power flow formulation to include frequency deviations and implicitly model generator primary and secondary control action…
Steady-State Simulation for Combined Transmission and Distribution Systems
Amritanshu Pandey, Larry Pileggi
The future electric grid will consist of significant penetration of renewable and distributed generation that is likely to create a homogenous transmission and distribution (T&D) s…
Enhanced Modelling Framework for Equivalent Circuit-Based Power System State Estimation
Aleksandar Jovicic, Marko Jereminov, Larry Pileggi +1
The equivalent split-circuit formulation is a novel approach that has recently been applied to a range of power system related problems. As a result, a linear and a nonlinear metho…
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…
A Probabilistic Approach to Power System State Estimation using a Linear Algorithm
Martin R. Wagner, Marko Jereminov, Amritanshu Pandey +1
An equivalent circuit formulation for power system analysis was demonstrated to improve robustness of Power Flow and enable more generalized modeling, including that for RTUs (Remo…
Robust and Efficient Power Flow Convergence with G-min Stepping Homotopy Method
Marko Jereminov, Athanasios Terzakis, Martin Wagner +2
Recent advances have shown that the circuit simulation algorithms that allow for solving highly nonlinear circuits of over one billion variables can be applicable to power system s…
Equivalent Circuit Programming for Estimating the State of a Power System
Marko Jereminov, Aleksandar Jovicic, Martin R. Wagner +2
An Equivalent Circuit Programming (ECP) approach that expresses the optimality conditions of an optimization problem in terms of an equivalent circuit model and uses circuit simula…
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…
Impact of Load Models on Power Flow Optimization
Marko Jereminov, Bryan Hooi, Amritanshu Pandey +3
Aggregated load models, such as PQ and ZIP, are used to represent the approximated load demand at specific buses in grid simulation and optimization problems. In this paper we exam…
