Abstract.A new control scheme for the operation of offshore wind farms connected through a VSC-HVDC link to the main onshore grid is presented in the paper. The control strategy has been developed to allow the islanded operation and blackstart of the wind farm as these requirements will probably be of great interest in the future due to the progressive increase of distributed generation. A complete model of the offshore wind farm with a VSC-HVDC link and its control scheme has been developed and analyzed through PSCAD simulations. Results show that the proposed control scheme is able to operate the plant under different steady-state and transient conditions. Key wordsOffshore wind power, VSC-HVDC transmission systems, islanded operation of wind farms, VSC control.

“…Literature reports only several HVRT strategies for FCWGs, which primarily uses additional auxiliary devices for the FCWG (Alharbi, Shiddiq Yunus, & Abu‐Siada, ; Chaudhary, Teodorescu, Rodriguez, & Kjær, ). Alharbi et al () proposed a STATCOM to ride‐through high voltage faults, where STATCOM absorbs reactive power from the network (essentially behaves as an inductor) to maintain voltage within upper limit stipulated by the grid code.…”

Electricity networks are evolving rapidly with the large-scale integration of power electronic (PE)-interfaced distributed renewable energy resources (DRERs). With this rapid deployment of PE-interfaced renewables, requirements set for the PE-interfaced DRERs have also evolved to maintain grid security and reliability. Fault ride-through (FRT) is an essential requirement which should be adhered by DRERs, which will ensure security and reliability of the power system during grid faults. This paper critically reviews the existing FRT standards (grid-code requirements) and FRT strategies implemented/ proposed for major DRERs, such as wind energy conversion systems (WECSs), solar photovoltaic (PV) systems, and microgrids. According to the review, robust FRT strategies are implemented/proposed DRERs, however, the FRT grid codes are presently developed with the perspective of both synchronous and renewable generation operating in the power system. However, this current approach should be augmented considering 100% PE-based renewable energy scenarios, and emerging issues, such as high penetration of PE-interfaced small-scale renewable generators (e.g., domestic solar-PV systems) and recurring grid faults, to achieve a sustainable renewable energy future. This article is categorized under: Concentrating Solar Power > Systems and Infrastructure Wind Power > Systems and Infrastructure Photovoltaics > Systems and Infrastructure K E Y W O R D S distributed renewable energy resources (DRERs), fault ride-through (FRT), gridcode requirements, microgrids, power electronic converters, solar-PV, wind energy conversion systems (WECSs)

This paper presents a recovery strategy that enables DC transmission systems based on voltage source converters to ride-through different ac faults with minimum current and voltage stresses on the converter switching devices. The proposed recovery strategy eliminates the trapped energy in the dc link during ac faults; as a result the rise in the dc link voltage is prevented. This may eliminate the need for the dc chopper in the dc link, as proposed in the literature, to dissipate the trapped energy. To demonstrate the effectiveness of the recovery strategy, several fault conditions are considered, including, symmetrical and asymmetrical faults. The proposed recovery strategy improves the resiliency of the VSC-HVDC transmission system to different ac faults, which can be summarized as follows: limited current contribution to the fault and limited current and voltage stress on the switching devices as the rise in the dc link voltage is significantly reduced or prevented
