“…In [64], the break-even distance for a farm of 1 GW was estimated to be 120-160 km. The aforementioned studies and [65][66][67][68][69] are summarized in Figure 18. At what distance cost parity between HVDC and HVAC transmission occurs depends on factors such as the need for reactive compensation, voltage levels and right of way, and will be more or less unique for every project.…”

Marine energy resources could be crucial in meeting the increased demand for clean electricity. To enable the use of marine energy resources, developing efficient and durable offshore electrical systems is vital. Currently, there are no large-scale commercial projects with marine energy resources, and the question of how to design such electrical systems is still not settled. A natural starting point in investigating this is to draw on experiences and research from offshore wind power. This article reviews different collection grid topologies and key components for AC and DC grid structures. The review covers aspects such as the type of components, operation and estimated costs of commercially available components. A DC collection grid can be especially suitable for offshore marine energy resources, since the transmission losses are expected to be lower, and the electrical components could possibly be made smaller. Therefore, five DC collection grid topologies are proposed and qualitatively evaluated for marine energy resources using submerged and non-submerged marine energy converters. The properties, advantages and disadvantages of the proposed topologies are discussed, and it is concluded that a suitable electrical system for a marine energy farm will most surely be based on a site-specific techno-economic analysis.

“…HVDC systems offer several advantages over AC power transmission systems, such as reactive power compensation and uniform current density in cables, all of which lead to increased power transmission capacity and distance when using cables of the same cross-sectional area [7], [8]. The break-even distance for the application of HVDC is reported to be approximately 50 km and 300 km for submarine cables and overhead lines, respectively [9], [10].…”

AC Fault Ride-Through Method of HVDC Interconnector for Islanded AC Grid With Offshore Wind Farm and Loads

This paper proposes an ac fault ride-through (FRT) method for high-voltage dc (HVDC) transmission systems that serve as an interconnector between the onshore ac grid and an islanded offshore ac grid. The conventional HVDC system for offshore wind farms has realized its FRT by consuming excess power by a braking resistor. However, the same method cannot be applied if the offshore ac grid includes not only wind farms but also various loads, which are recently envisioned in multipurpose interconnectors or energy islands. In this article, a novel FRT method based on voltage control for HVDC interconnectors operating with bidirectional power flow is proposed. The proposed method curtails the ac voltage formed by the offshore converter according to the converter's dc current and voltage. The effectiveness of the proposed FRT method is established through experiments on a mini model.INDEX TERMS Deloading, islanding, HVDC transmission, fault ride-through (FRT), voltage control.
