The effectiveness of using IEC61660 for characterising short-circuit currents of future low voltage DC distribution networks

Low voltage direct current (LVDC) distribution systems have the potential to be considered as an enabler of increased penetration of distributed renewables, electric vehicles, and heat pump systems. They do however present significant challenges for understanding fault behaviour and effective protection systems. This paper presents these challenges, and investigates the effectiveness of using IEC61660 for the short-circuit characterisation of LVDC networks.
