Nowadays, wind is considered as a remarkable renewable energy source to be implemented in power systems. Most wind power plant experiences have been based on onshore installations, as they are considered as a mature technological solution by the electricity sector. However, future power scenarios and roadmaps promote offshore power plants as an alternative and additional power generation source, especially in some regions such as the North and Baltic seas. According to this framework, the present paper discusses and reviews trends and perspectives of offshore wind power plants for massive offshore wind power integration into future power systems. Different offshore trends, including turbine capacity, wind power plant capacity as well as water depth and distance from the shore, are discussed. In addition, electrical transmission high voltage alternating current (HVAC) and high voltage direct current (HVDC) solutions are described by considering the advantages and technical limitations of these alternatives. Several future advancements focused on increasing the offshore wind energy capacity currently under analysis are also included in the paper.

“…HANKS to the extensive research and field applications in the past years, modular multilevel converter based highvoltage direct-current (MMC-HVDC) technology is getting mature and has been deployed in many projects including multiterminal HVDC networks [1]- [2]. Currently, most of the commissioned MMC HVDC projects are symmetrical monopoles [3]. With the increasing demand of bulk-power transmission and high reliability of power supply, there will be more applications using bipoles.…”

The valve-side single-phase-to-ground (SPG) faults in half-bridge modular multilevel converter (HB-MMC) based bipolar high-voltage direct-current (HVDC) systems induce some special fault consequences: overvoltage on the submodule (SM) capacitors in converter upper arms and non-zero-crossing currents in the grid-side ac circuit breaker (ACCB). In this letter, a protection strategy based on converter embedded double-thyristors is proposed to address these issues. The double-thyristors are installed in parallel with each SM in the lower arms of the converter. By triggering the double-thyristors, the SPG fault is converted into a three-phase short-circuit which ensures current zerocrossings in the grid-side ACCB. Moreover, as the voltages of converter AC buses are clamped by the ground through the triggered double-thyristors, the upper arm overvoltage is mitigated. The effectiveness of the proposed protection strategy has been verified in a bipolar HB-MMC HVDC link built in PSCAD/EMTDC.

“…In the UK and Europe ambitious plans exist for offshore wind development, for many of which HVDC is the preferred connection option, with further links planned to Europe and embedded in the UK network [5]. Optimizing the layout of the plant in terms of space saving, enabling incorporation of future technology, and access for maintenance and safety is increasingly important: and it is here that the increased use of 3DV could play a major part.…”
