AbstractThis paper will provide an update on the current state of the art with regards to the use of medium voltage direct current (henceforth abbreviated as MVDC) links to provide transmission network style flexibility to constrained distribution networks. MVDC is starting to be considered as an option for enhancing transfer capacity and providing increased power quality at distribution networks. Certain configurations can provide controlled power transfer between two 11 or 33 kV distribution groups, without affecting short-circuit levels, voltage differences, loop flows or limitations due to phase-angle differences. There are future technology opportunities including enhancement of existing corridors through the conversion of existing AC lines to DC. This paper will provide a technology update as well as information on recently deployed projects. It will summarise the benefits of MVDC and the applications where it may provide a competitive or preferential alternative solution to conventional technology.Keywords: MVDC, distribution, VSCCite this ArticleAvik Ganguly, Lalit Tejwani.
