The Padé matrix pencil method with spurious pole information assimilation

Daniel Tylavsky, Songyan Li, Di Shi

We present a novel method for calculating Padé approximants that is capable of eliminating spurious poles placed at the point of development and of identifying and eliminating spur…

Root Distribution in Padé Approximants and its Effect on Holomorphic Embedding Method Convergence

Songyan Li, Abhinav Dronamraju, Daniel Tylavsky

The requirement for solving nonlinear algebraic equations is ubiquitous in the field of electric power system simulations. While Newton-based methods have been used to advantage, t…

Implications of Stahl's Theorems to Holomorphic Embedding Pt. 1: Theoretical Convergence

Songyan Li, Daniel Tylavsky, Di Shi +1

What has become known as Stahl's Theorem in power engineering circles has been used to justify a convergence guarantee of the Holormorphic Embedding Method (HEM) as it applies to t…

Two-Bus Holomorphic Embedding Method-based Equivalents and Weak-Bus Determination

Shruti Rao, Daniel Tylavsky, Weili Yi +3

A new method of solving the power-flow problem, the holomorphically embedded load-flow method (HELM) is theoretically guaranteed to find the high-voltage solution, if one exists, u…
