“…Furthermore, the power distribution system of the terrestrial mines are traditionally AC, while there has been a tendency toward DC in recent years, due to the wider development of frequency converters [9,10]. Consequently, it would be wise to investigate the DC alternatives for subsea mines as well.…”

The main goal of this paper is to give a framework for designing the power distribution system for seafloor mining vehicles operating in deep and ultra-deep waters. As the starting point prior to the design, the tethered seafloor mining vehicles are compared with their counterparts in the terrestrial mines and the well-developed remotely operated vehicles. Then, various power distribution alternatives are studied and compared taking into account the main design criteria such as efficiency and size of components. Although the major loads of these vehicles are AC motor loads for drilling, pumping and locomotion, it is concluded that the DC distribution, both in topside and subsea sections, is the best option. Typical values for efficiency and volume grades (normalized values) for the major components in the distribution system have been considered in the calculations.

“…The DC-DC converters can be galvanic isolated or non-isolated [5,6]. Several isolated topologies of DC-DC converters have been proposed, such as the modular multilevel dual-active bridge and the inductor-capacitorinductor (LCL) based DC-DC converters, both of which offer independent AC-DC conversion and inherent DC fault tolerate capability [7,8]. However, they require two AC/DC conversion stages, resulting in higher converter power rating and operating power loss.…”

A hybrid AC/DC hub is proposed in this study, where a modular multilevel converter and a line-commutated converter are paralleled at the AC side to integrate onshore wind power, and connected in series at the DC sides to interconnect two DC networks with different voltages. The hybrid AC/DC hub facilitates wind power integration and DC network interconnection with reduced converter ratings and power losses when compared with the 'conventional' approach using DC-DC converters. To investigate the design requirement and performance of the hybrid AC/DC hub, power flow analysis is assessed to evaluate the converter power rating requirement. To ride through DC faults at either side of the interconnected DC networks, a coordinated DC fault protection for the hybrid AC/DC hub is proposed and studied. Simulation results in PSCAD/EMTDC verify the feasibility and effectiveness of the proposed control and protection of the hybrid AC/DC hub under power flow change, AC and DC fault conditions.

“…Nowadays, the use of high step‐up dc–dc converters (HSDCs) has increased due to the existence of various renewable energy sources [1, 2], the increased use of fuel cells [3], hybrid electric vehicles and transportation systems [4, 5] etc. Additionally, the mentioned converters have been widely used in modern applications such as industry [6], DC motor drives [7, 8], DC smart grids [9], uninterruptable power supplies [10, 11] etc. due to their high‐voltage gain.…”
