Abstract

Unidirectional power flow voltage source converter high voltage direct current (VSC-HVDC) systems can be advantageously used in future dc subsea electric transmission and distribution systems (DC-SETDS) in order to reduce cost, increase efficiency and reliability. This work proposes a unidirectional modular multilevel converter (uMMC) suitable for VSC-HVDC systems used in DC-SETDS. The main advantage of the proposal is the reduced number of active switches, lowering costs and increasing reliability. Suitable currents and voltages control strategies are presented, as well as simulation results.
