A Study on the Optimal Configuration of Offshore Substation Transformers
EnergiesThe growing scale of offshore wind farms and increasing transmission distances has driven the demand for optimized offshore substation (OSS) configurations. This study proposes a comprehensive techno-economic framework to minimize the total lifecycle cost (LCC) of an OSS by determining the optimal number of OSSs and transformers considering wind farm ...

Offshore underwater substation for wave energy converter arrays
IET Renewable Power Generation, 2010 In this study, the design, construction, deployment and operation of an offshore underwater substation is discussed. The seabed placed substation interconnects three linear generator wave energy converters (WECs) at the Swedish Lysekil wave energy research site. The power from the WECs fluctuates because of their direct-driven topology.

Unified System Analysis for Time-Variant Reliability of a Floating Offshore Substation
Journal of Marine Science and Engineering, 2023 Offshore wind is planned to become the first source of energy by 2050. That requires installing turbines in deeper seas. It is shown that only floating wind turbines will allow dealing with this challenge while keeping a reasonable cost of energy production and transport according to the levelized cost of electricity.

Operations Research Perspectives, 2022 Despite a lot of research about predictive maintenance for onshore and offshore windmill farms, nearly no investigation has been performed to obtain the optimal sequence in which windmills are to be served in a predefined time frame. The higher fuel costs and the increasing time pressure on maintenance jobs urge the need for optimisation, so offshore ...

Offshore substation workers’ exposure to harmful factors – Actions minimizing risk of hazards
Medycyna Pracy, 2015 The current development of electric power industry in Poland, especially in the field of renewable energy sources, including wind power, brings about the need to introduce legislation on new work environment. The development of occupational safety and health (OSH) regulations that must be met by new workplaces, such as offshore substations becomes ...

Control of offshore marine substation for grid-connection of a wave power farm
International Journal of Marine Energy, 2014 Abstract To grid-connect an offshore wave power farm, an intermediate marine substation is suggested. As a part of the Uppsala University wave power project, a marine substation has been designed, assembled and deployed at sea. The substation is capable of connecting up to seven wave energy converters (WECs), and to transfer the power to the onshore ...

Study on Design and Constructure of Offshore Substation
Journal of Physics: Conference Series, 2021 Abstract In recently years, there are more than 70% of power generated by coal station. Based on this, it can be shown that fossil fuels are the main consumption for generating energy. Burning fossil fuels will produce a lot of carbon dioxide and other harmful gas.

Maintenance philosophy for an unmanned platform: A case study for an Offshore wind substation
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Unmanned installations introduce new challenges for the operations and maintenance. In many offshore windfarms there is a need for offshore substations and these substations can be designed as unmanned installations. Thus, the purpose of this paper is to review and discuss the available maintenance philosophies for unmanned ...

Optimal Design of Power Grid and Location of Offshore Substation for Offshore Wind Power Plant
The Transactions of The Korean Institute of Electrical Engineers, 2015 Abstract – This paper presents the methodology for optimal design of power grid for offshore wind power plant (OWPP) and optimum location of offshore substation. The proposed optimization process is based on a genetic algorithm, where the objective cost model is composed of investment, power loss, repair, and reliability cost using the net present ...
