Abstract
Circuit simulation for power grid models leads to the challenge of model order reduction for linear descriptor systems with many ports. Based on the ESVDMOR idea of Feldmann and Liu [Proceedings of the 2004 IEEE/ACMInternational Conference on Computer-aided design (2004)],we have proposed several numerical improvements for ESVDMOR to enable the application to sparse and very largescale systems. In further investigations we have proven that ESVDMOR is, under a few assumptions, stability, passivity, and reciprocity preserving. This paper provides a survey of these developments and outlines error estimation for ESVDMOR.
