Centralized calibration of power system dynamic models using variational data assimilation
Ahmed Attia, D. Adrian Maldonado, Emil Constantinescu +1
This paper presents a novel centralized, variational data assimilation approach for calibrating transient dynamic models in electrical power systems, focusing on load model paramet…
Heuristic Algorithms for Placing Geomagnetically Induced Current Blocking Devices
Minseok Ryu, Ahmed Attia, Arthur Barnes +3
We propose a new heuristic approach for solving the challenge of determining optimal placements for geomagnetically induced current blocking devices on electrical grids. Traditiona…
Robust A-Optimal Experimental Design for Bayesian Inverse Problems
Ahmed Attia, Sven Leyffer, Todd Munson
Optimal design of experiments for Bayesian inverse problems has recently gained wide popularity and attracted much attention, especially in the computational science and Bayesian i…
A Sampling Filter for Non-Gaussian Data Assimilation
Ahmed Attia, Adrian Sandu
Data assimilation combines information from models, measurements, and priors to estimate the state of a dynamical system such as the atmosphere. The Ensemble Kalman filter (EnKF) i…
