Special Issue Information

Dear Colleagues,

We are inviting submissions to a Special Issue on “Power Systems for Offshore Renewable Energy”. To ensure social welfare in the future, a central issue will be to secure long-term sustainable solutions for electricity generation. One promising source is energy from the oceans; in this case ocean waves and tides. However, despite the enormous potential in the source, researchers and engineers are still struggling to find cost effective technical solutions. One central aspect for the progress in the field is the importance of conducting research and development of technology from a holistic standpoint. The development should focus on finding sustainable solutions with a high utility factor. This Special Issue will focus on the research and progress within power systems and grid connection issues in the offshore renewable area, including (but not limited to) articles or review papers on connection of marine renewable energy technologies to local grids, small facilities or specific functions (e.g., desalination plants for freshwater production); analyzing system stability, power fluctuations and intermittency; presenting control systems or circuit designs to enhance the power quality and meet system requirements, discuss load variations, etc., through a holistic system approach, describing why the proposed system would benefit society (economically, socially and ecologically), as well as how it could be implemented, or which steps of future research (e.g., offshore experiments) that would be necessary to validate the presented study and increase the pace towards viable grid connected wave- and tidal energy systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Floating turbines are attracting increasing interest today. However, the power generation efficiency of a floating turbine is highly dependent on its motion stability in sea water. This issue is more marked, particularly when the floating turbines operate in relatively shallow water. In order to address this issue, a new concept motion stabilizer is studied in this paper. It is a completely passive device consisting of a number of heave plates. The plates are connected to the foundation of the floating wind turbine via structural arms. Since the heave plates are completely, rather than partially, exposed to water, all surfaces of them can be fully utilized to create the damping forces required to stabilize the floating wind turbine. Moreover, their stabilizing effect can be further amplified due to the application of the structural arms. This is because torques will be generated by the damping forces via the structural arms, and then applied to stabilizing the floating turbine. To verify the proposed concept motion stabilizer, its practical effectiveness on motion reduction is investigated in this paper. Both numerical and experimental testing results have shown that after using the proposed concept stabilizer, the motion stability of the floating turbine has been successfully improved over a wide range of wave periods even in relatively shallow water. Moreover, the comparison has shown that the stabilizer is more effective in stabilizing the floating wind turbine than single heave plate does. This suggests that the proposed concept stabilizer may provide a potentially viable solution for stabilizing floating wind turbines. Full article
