Abstract
This paper introduces a modal analysis approach
termed as the Iterative Matrix Pencil method. It uses
the Matrix Pencil Method as the primary tool for mode
identification, and adds to it by utilizing the concept
of a cost function in order to reduce the number of
signals needed to identify the modes for a large system.
The method is tested for a variety of large synthetic
power grids in this paper, with the cost function being
reported to measure accuracy. A sensitivity analysis is
also considered, showing how this new method behaves
when adjusting the two primary user-based inputs; the
number of iterations, and the SVD threshold.
