This is a data acquisition-based methodology to construct a state-space model of black-box Voltage Source Converters (VSCs) for application in small-signal stability analysis in modern power-systems using the Component Connection Method (CCM). This approach determines the fitted state-space (FSS) model through the frequency-domain (FD) identification of the VSC via the input-output responses of voltage and current (even frequency) at the point of connection (POC).
The fitss has been developed as part of the MSCA-ADOreD project, funded by the European Union’s Horizon Europe Research and Innovation Programme under the Marie Skłodowska-Curie grant agreement No. 101073554.
The fitss has been validated and documented in the following scientific publication. Users must cite this work in any academic, scientific, or industrial document where the tool is used, following the terms of the GPL-3.0 license under which the fitss is distributed.
