Towards Faster Givens Rotations Based Power System State Estimator
Nunierically stable and computationally efficient Power System Statc Estimation (PSSE) algorithms are designed using Orthogonalization (QR decomposition) approach. They u3e Givens rotations for orthogonalization which enables sparsity exploitation during factorization of large sparse auginentecl Ja,cobian. Apriori row and column ordering is usiially performed to reduce intermediate a.nd and ove...
متن کاملDynamic State Estimator Based on Wide Area Measurement System During Power System Electromechanical Transient Process
The wide area measurement system (WAMS) developed rapidly in recent years [1-3]. It has been applied to the studies on many topics in monitoring and control of power systems. But as a kind of measurement system, WAMS has the measurement error and bad data unavoidably. The steady measurement errors of WAMS have been prescribed in corresponding IEEE standard [4], but the dynamic measurement error...
متن کاملEfficient coordinate-descent for orthogonal matrices through Givens rotations
Optimizing over the set of orthogonal matrices is a central component in problems like sparse-PCA or tensor decomposition. Unfortunately, such optimization is hard since simple operations on orthogonal matrices easily break orthogonality, and correcting orthogonality usually costs a large amount of computation. Here we propose a framework for optimizing orthogonal matrices, that is the parallel...
متن کاملA new family of EVD tracking algorithms using Givens rotations
In this work, we derive new algorithms for tracking the eigenvalue decomposition (EVD) of a time-varying data co-variance matrix. These algorithms have parallel structures, low operation counts and good convergence behavior. Their main feature is the use of Givens rotations to update the eigenvector estimates. As a result, orthonormality of the latter can be maintained at all time, which is cri...
متن کاملPipelined RLS adaptive architecture using relaxed Givens rotations (RGR)
In this paper, we focus on developing a new relaxed Givens rotations (RGR)-RLS algorithm and the corresponding RGR-RLS systolic array. The resulting algorithm and architecture possess fine-grain pipelining, nearly the same convergence as the QRD-RLS, good robustness for , and square-root free computation with a little area overhead.
