Successive eigenvalue relaxation: a new method for the generalized eigenvalue problem and convergence estimates [PDF]

open access: yes, 2001
We present a new subspace iteration method for the efficient computation of several smallest eigenvalues of the generalized eigenvalue problem Au = lambda Bu for symmetric positive definite operators A and B.

A Recent Analytical Approach for Analysis of Sub-Synchronous Resonance in Doubly-Fed Induction Generator-Based Wind Farm

open access: yesIEEE Access, 2021
Sub-synchronous resonance (SSR) phenomenon occurs due to the interaction between wind turbine generators and series-compensated transmission lines. A doubly-fed induction generator (DFIG) is considered one of the most widely implemented generators in ...

On a Fuzzy Boundary Value Problem with an Eigenvalue Parameter Contained in the Boundary Condition

open access: yesCumhuriyet Science Journal, 2019
A fuzzy boundary value problem with aneigenvalue parameter contained in the boundary condition is investigated inthis paper. The examination is made under the approach of Hukuharadifferentiability.

Computing tensor Z-eigenpairs via an alternating direction method [PDF]

open access: yesPeerJ Computer Science, 2023
Tensor eigenproblems have wide applications in blind source separation, magnetic resonance imaging, and molecular conformation. In this study, we explore an alternating direction method for computing the largest or smallest Z-eigenvalue and corresponding

Dynamic Interactions between Parallel Grid-Forming Inverters in a Microgrid

open access: yesApplied Sciences, 2023
The potential instability issues caused by the dynamic interactions between parallel grid-forming inverters are examined. The approach adopted for analysis is s-domain admittance-based eigenvalue and mode shape analysis.

Fundamental limitations of the eigenvalue continuation approach [PDF]

open access: yes, 2022
[EN] In this work, we show that the eigenvalue continuation approach introduced recently by Frame et al. [Phys. Rev. Lett. 121, 032501 (2018)], despite its many advantages, has some fundamental limitations which cannot be overcome when strongly ...

Attack detection design for dc microgrid using eigenvalue assignment approach

open access: yesEnergy Reports, 2021
DC microgrids (MGs) are complex systems connecting a number of renewable energy sources to different types of loads based on distributed networks. However, the strong reliance on communication networks makes DC MGs vulnerable to intentional cyber-attacks.

Existence Theorems for Some Classes of Boundary Value Problems Involving the P(X)-Laplacian

open access: yesNonlinear Analysis, 2008
We prove an alternative for a nonlinear eigenvalue problem involving the p(x)-Laplacian and study a subcritical boundary value problem for the same operator.
