Title: Comparison of compensation methods applied to the analysis of topological changes in electrical networks
Author: Castro, CA

Abstract: This paper focuses on compensation methods used in the analysis of topological changes in power systems. The objectives are twofold: (a) listing the main methods available in the literature and (b) comparing them. Methods based on the inverse matrix modification lemma, diakoptics and sensitivities are implemented and tested. The comparison is based on memory storage requirements, precision of results, number of operations (mult/div and sum/sub) and processing times. It is shown that there is a best compensation method to be used depending on the adopted network power flow equations. It is also shown that the compensation method based on sensitivities applied to changes in the Jacobian matrix has the best performance among all other methods. The results of simulations using those methods applied to a number of small and large power systems are presented. (C) 1997 Elsevier Science Ltd.
