Special Issue Information

Dear Colleagues,

The new future of power production within the wind energy sector is floating offshore wind farms. This emerging technology is opening new possibilities for wind power locations and will play a critical role in the transition to a cleaner energy supply, contributing significantly to an increase in wind power. However, the challenges faced in developing this new technology are significant, and outstanding research and innovation are required in areas such as design, energy extraction, installation, maintenance, monitoring, etc., to minimize risks and maximize the chances of a successful future installations.

This Special Issue aims to address the challenges the floating offshore wind turbines sector is facing by providing innovative research ideas and reporting current advances in the field of modeling and simulation of wind farms. Contributions across a broad spectrum of scientific and engineering disciplines concerned with technological developments in offshore wind power generation, energy conversion, and integration are of great importance for the journal.

This Special Issue seeks to disseminate knowledge on various aspects of offshore wind farm modeling and simulation and promote fundamental, multidisciplinary, and applied research in the field. This Special Issue offers a significant opportunity for reporting advancements in the field that can help to realize the potential of floating offshore wind farms. This Special Issue covers but is not limited to a wide range of topics, including:

Offshore wind farms

How Does the Accessibility of Floating Wind Farm Sites Compare to Existing Fixed Bottom Sites?

Abstract

Offshore wind is poised for huge growth in the coming years, the UK government has set targets of 40 GW of offshore wind, including 1 GW of floating wind, to be installed in the UK by 2030. Many proposed wind development sites are in deeper waters, farther from shore and will therefore need to be developed as floating wind sites. Developing sites in deeper waters provides access to higher, more consistent wind speeds, however this also means increased wave heights and tougher operating conditions. This makes the challenge of site accessibility critical to the goal of lowering the costs of offshore wind. Accessibility is the amount of time that vessels can safely access a given site. The objective of this study was to make a comparison of the accessibility of potential future floating wind sites to existing fixed bottom wind farm sites. Accessibility was calculated by developing Matlab code using established techniques and definitions found in the literature. A case study was then completed using sites in Scottish waters proposed for development as part of the Scotwind leasing plan. The majority of the Scotwind sites will need to be developed as floating wind sites due to the large water depths. This study assesses the accessibility of the Scotwind leasing sites and compares them to a typical fixed bottom site. The study found that accessibility will be a greater challenge for floating farm wind sites compared to fixed bottom sites. Increased access to vessels that can operate in larger wave heights will likely be necessary to operate and maintain floating wind farm sites. Full article

Abstract

Vertical Axis Wind Turbines (VAWTs) are omni-directional, low-cost, low-efficiency wind power extractors. A conventional drag-based VAWT consists of multiple thin rotor blades with a typical peak Tip Speed Ratio (λ) of < 1. Their lower cut-in speed and maintenance cost make them ideal for power generation in urban environments. Numerous studies have been carried out analysing steady operation of VAWTs and quantifying their performance characteristics, however, minimal attention has been paid to their start-up dynamics. There are a few recent studies in which start-up dynamics of lift-based VAWTs have been analysed but such studies for drag-based VAWTs are severely limited. In this study, start-up dynamics of a conventional multi-blade drag-based VAWT have been numerically investigated using a time-dependant Computational Fluid Dynamics (CFD) solver. In order to enhance the start-up characteristics of the drag-based VAWT, a stator has been integrated in the design assembly. The numerical results obtained in this study indicate that an appropriately designed stator can significantly enhance the start-up of a VAWT by directing the flow towards the rotor blades, leading to higher rotational velocity (ω) and λ. With the addition of a stator, the flow fields downstream the VAWT becomes more uniform. Full article
