A priori error estimation of the structure-preserving modal model reduction by state residualization of a grid forming converter for use in 100% power electronics transmission systems
TypeCommunications avec actes
This article deals with the model order reduction by state residualization of power electronic converters. It presents a method to a priori estimate the error induced by this reduction. This method helps choosing the most suitable reduced model, the one that minimizes the error, depending on the simulated events. When applied to a system with several converters, it helps choosing which converter to reduce and how much, in order to simplify the models while keeping a sufficient accuracy.

Simplified converters models for the analysis and simulation of large transmission systems using 100% power electronics COSSART, Quentin; COLAS, Frédéric; KESTELYN, Xavier (2018)In this paper, a model order reduction method is proposed, to simplify power electronics converters and allow simulating large transmission systems using 100% power electronics. Unlike existing methods it keeps the system's ...
