Electrical Components for Marine Renewable Energy Arrays: A Techno-Economic Review

This paper presents a review of the main electrical components that are expected to be present in marine renewable energy arrays. The review is put in context by appraising the current needs of the industry and identifying the key components required in both device and array-scale developments. For each component, electrical, mechanical and cost considerations are discussed; with quantitative data collected during the review made freely available for use by the community via an open access online repository. This data collection updates previous research and addresses gaps specific to emerging offshore technologies, such as marine and floating wind, and provides a comprehensive resource for the techno-economic assessment of offshore energy arrays

A 4 GW AC submarine Turkish power grid reinforcement under the Dardanelles Strait

none5The paper describes the 400 kV AC submarine link under the Dardanelles Strait composed of 12 submarine armoured single-core XLPE-insulated cables (plus a back-up power cable). The link consists of two parallel-operated double-circuit link named Lâpseki-Sütlüce I and Lâpseki-Sütlüce II. The whole transmissible power is 4000 MW (1000 MW per circuit) and the average length for a single-core cable is about 4,6 km: the submarine cables are part of overhead lines. The paper gives a wide overview of the cable installations and chiefly of the cable protections on the seabed: different protection choices have been extensively used (i.e. water jetting and mattressing).noneBenato, R.; Balanuye, I.; Koksal, F.; Ozan, N.; Ozdemirci, E.Benato, R.; Balanuye, I.; Koksal, F.; Ozan, N.; Ozdemirci, E
