(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In an effort to minimize the power disruption between a dc grid and ac grids that host power converters during ac and dc network faults, this paper proposes a novel converter station structure to improve ac and dc fault ...
Quasi two-level operation of modular multilevel converter for use in a high-power DC transformer with DC fault isolation capability
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
DC fault protection is one challenge impeding the development of multiterminal dc grids. The absence of manufacturing and operational standards has led to many point-to-point HVDC links built at different voltage levels, ...
Modular multilevel structure of a high power dual active bridge DC transformer with stepped two-level output
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper addresses the issues of dc voltage matching and dc fault protection in potential super-grids. An approach for high power dc-dc conversion is proposed and analyzed. A front-to-front connection of modular-multilevel ...
