1. An electric power system comprising first and second direct voltage buses wherein:
the electric power system further comprises at least two bus-tie links connected in parallel between the first and second direct voltage buses,
each of the bus-tie links having a first pole connected to first poles of the first and second direct voltage buses and a second pole connected to second poles of the first and second direct voltage buses,
each of the bus-tie links comprises at least one capacitor between the first and second poles of the bus-tie link, and
at least the first pole of each of the bus-tie links is connected via overcurrent protection devices to the first poles of the first and second direct voltage buses, each of the overcurrent protection devices being configured to break current in response to an overcurrent situation of the overcurrent protection device.
