Abstract
An electric power system includes direct voltage buses () and at least two bus-tie links (-) each being connected between the direct voltage buses. Each bus-tie link has at least one capacitor (-) between positive and negative poles of the bus-tie link. At least one pole of each bus-tie link is connected via overcurrent protection devices (-), such as fuses, to respective poles () of the direct voltage buses. The capacitors of the bus-tie links form a distributed capacitor storage that is capable of providing fault currents to the electric power system to operate overcurrent protection devices so that zonal selectivity is achieved. The electric power system can be for example an electric power system of a ship or another marine vessel.
