Dynamics and Control of Offshore and Onshore Wind Turbine Structures

Dear Colleagues,

We are organizing a special issue that may be of interest to you. As *Guest Editor*, I cordially invite you to submit a manuscript for consideration and possible publication in a special issue on "Dynamics and Control of Offshore and Onshore Wind Turbine Structures" to be published in *Energies* (http://www.mdpi.com/journal/energies), an open access journal publishing related scientific research and studies, is published by MDPI online monthly. Since its launch in 2008, the journal has been indexed by Science Citation Index Expanded, COMPENDEX and other large databases. The latest Impact Factor for 2019 is 2.702.

Renewable energies, and particularly wind energy, are playing a decisive role on helping to meet the global energy demand in an eco-friendly and clean environment. Along with well-established status of onshore wind, offshore wind turbines (both floating and fixed in the seabed) have emerged as a favorable solution for countries with sea waters. However, wind turbine structures are subject to large loads and undesirable vibrations caused by prolonged strong winds, sea currents as well as large waves, which may reduce energy efficiency and lead to damage (in addition to shortening the fatigue life). Hence, reducing the load impact on these land-based and marine structures is a fundamental challenge in order to increase reliability, and possibly reduce maintenance. Wind turbine control methods would be enhanced and ultimately, energy extraction could then be optimized.

In order to address these issues, the identification of computational models that can represent these strongly non-linear systems is essential. Additionally, various control aspects involved in the performance of these renewable energy solutions should also be addressed in order to improve the energy extraction efficiency and reduce vibration, leading to the increased fatigue life.

This Special Issue will focus on new approaches for the modelling, simulation, and control of offshore and onshore wind turbines. Topics of interest for publication include, but are not limited to:

• Modelling and identification of offshore and onshore wind turbine structures;
• Wind and waves models for wind turbines, wind- and waves-structure interaction;
• Soil- and seabed-structure interaction, including land subsidence;
• Offshore and onshore wind turbines vibration analysis;
• Offshore and onshore wind turbine control problems, including structural control;
• Optimisation of wind turbines performance and fatigue life;
• Energy efficiency of offshore and onshore wind turbines.

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 250 words) can be sent to the Editorial Office for assessment.

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.
