DC Fault Current Analysis and Control for Modular Multilevel Converters
… near ideal current and voltage scalability. The fault response, on the other hand, is a big challenge for the MVDC distribution systems and the traditional MMCs with the Half-Bridge submodule configuration, especially when a DC short circuit fault happens. In this study, the fault current …

A hybrid solution for distributed energy storage for microgeneration in microgrids: Design of the electronic power and control system
… storage units are interfaced to the main system through dedicated power converters. The control schemes implemented in these converters need to be coordinated as to manage the power flows according to the system performance requirements. The main objective of the research is, thus, to propose and …
