Assesment of soft error sensitivity of power flow analysis
Yetkin, Emrullah Fatih (Gazi Univ, Fac Engineering Architecture, 2023)Today's power systems are large and interconnected to each other with many buses, lines, loads, and generators. Even the solution of a single snapshot of the system for specific conditions requires the solution of systems ... -
ON SOFT ERRORS IN THE CONJUGATE GRADIENT METHOD: SENSITIVITY AND ROBUST NUMERICAL DETECTION
Agullo, Emmanuel; Cools, Siegfried; Yetkin, Emrullah Fatih; Giraud, Luc; Schenkels, Nick; Vanroose, Wim (SIAM PUBLICATIONS, 2020)The conjugate gradient (CG) method is the most widely used iterative scheme for the solution of large sparse systems of linear equations when the matrix is symmetric positive definite. Although more than 60 years old, it ... -
A sparsity-preserving spectral preconditioner for power flow analysis
Yetkin, Emrullah Fatih; Dağ, Hasan (TUBITAK Scientific & Technical Research Council Turkey, 2016)Due to the ever-increasing demand for more detailed and accurate power system simulations the dimensions of mathematical models increase. Although the traditional direct linear equation solvers based on LU factorization ...
