“…The aforementioned studies did not consider the use of HVDC diode rectifier DR stations. To the authors knowledge, the only published stability analysis of a point-to-point HVDC diode rectifier connected off-shore WPP was carried out in [16] and recently in [17]. However, [16] included only point-to-point links and did not cover important aspects required for an accurate model, namely, the use of a precise dynamic model of the diode rectifier unit, the influence of the on-shore grid and a thorough validation against EMT (PSCAD) models.…”

This paper presents a diode rectifier (DR)‐based hybrid converter topology for high‐voltage direct current (HVDC) transmission system with offshore wind farms (OWFs). The hybrid converter consists of a DR and an auxiliary converter. A high conversion ratio ac/dc converter is designed as the auxiliary converter, which can form the offshore grid voltage for OWFs to achieve black‐start. Under steady state, all the active power output from OWFs is delivered through the DR. Meanwhile, the auxiliary converter is able to compensate the reactive power and harmonic currents of the system. Comparing with the conventional modular multilevel converter (MMC), the number of submodules (SM) of the proposed hybrid converter is significantly reduced, which decreases the construction cost and size of the system. The topology and operation principle of the hybrid HVDC converter are introduced. Then the corresponding control strategy is designed to achieve energy balance and power transmission. Based on the mathematic model, a design method for the parameters of the auxiliary converter is proposed. Finally, the feasibility of the proposed hybrid HVDC converter is verified by both the simulation and hardware‐in‐the‐loop experiment results.

The diode‐rectifier (DR)‐based high‐voltage direct current (HVDC) transmission is regarded as a low‐cost alternative to the HVDC transmission for offshore wind farms (OWFs) integration. However, the DR would generate harmonic voltages in the offshore grid, which greatly affects the power quality. To solve this problem, this paper utilizes a parallel‐connected small‐capacity auxiliary converter to suppress the harmonic voltages and provide black‐start energy for the OWFs. In addition, the submodule branches (SMBs) of the auxiliary converter can be used as part of the HVDC chopper. On this basis, a coordinated grid fault ride‐through (FRT) strategy is proposed in this paper. After a grid fault occurs, the HVDC chopper constructed by the auxiliary converter is able to constrain the DC‐link voltage. At the same time, the OWFs are controlled to reduce the output active power. As a result, the cost of the FRT can be significantly reduced. The proposed harmonic voltage suppression and the FRT method are verified through the simulation model in Simulink.
