Mr. Wang, Q. (author), Xu, Tangjie (author), von Terzi, D.A. (author), Xia, Wei (author), Wang, Zhenhai (author), Zhang, Haoran (author)In existing wind farms, the overall power output can be increased through yaw control. However, the cooperative control of start/stop, yaw and turbines positions is often overlooked, leading to wake superposition to downstream wind turbines and suboptimal power output. This paper proposes a synchronized optimized method that considers start...journal article 2024

van der Hoek, D.C. (author), Van den Abbeele, B.H.L. (author), Ferreira, Carlos (author), van Wingerden, J.W. (author)Wind farm control can play a key role in reducing the negative impact of wakes on wind turbine power production. The helix approach is a recent innovation in the field of wind farm control, which employs individual blade pitch control to induce a helical velocity profile in a wind turbine wake. This forced meandering of the wake has turned...journal article 2024

Kingma, Enzo M. (author), ter Hofstede, R. (author), Kardinaal, Edwin (author), Bakker, Rebecca (author), Bittner, Oliver (author), van der Weide, Babeth (author), Coolen, Joop W.P. (author)In the past, a large part of the seabed of the southern North Sea was covered by hard substrates, including oyster beds, coarse peat banks, and glacial erratics. Human activities, particularly bottom trawl fisheries, led to the disappearance of most of these hard substrates, resulting in the loss of its associated diverse benthic life as well...journal article 2024

Cipriani, L. (author), Destro, Alessandro (author)Beginning in the fourteenth century, along the northeastern Italian coastline, Venetians began to create a series of hydraulic structures called “fishing valleys,” which combined aquaculture production with lagoon and seawater management. According to the current scenarios provided by the Intergovernmental Panel on Climate Change, the coastal...journal article 2023

Iglesias, Cristina Botana (author), Novas, María (author)In the first quarter of the 21st century, we are facing the profound impact of overexploitation of the Earth and the consolidation of a globalized capitalism with deep colonial and patriarchal roots. Two major challenges converge at this crucial point: the climate crisis and growing social inequality. In urban and territorial studies, we tend...journal article 2023

Persello, Claudio (author), Grift, Jeroen (author), Fan, X. (author), Paris, Claudia (author), Hansch, Ronny (author), Koeva, Mila (author), Nelson, Andrew (author)Agricultural field polygons within smallholder farming systems are essential to facilitate the collection of geo-spatial data useful for farmers, managers, and policymakers. However, the limited availability of training labels poses a challenge in developing supervised methods to accurately delineate field boundaries using Earth observation ...journal article 2023

Koreman, M.C.J. (author), Korthals Altes, W.K. (author)Across the European Union, farm modernisation results in vacant farm buildings in agricultural areas. This is an issue at the crossroads of rural development and spatial planning. The debate often revolves around the options of either demolishing these buildings or re-using them for residential purposes. There is less emphasis, however, on re...journal article 2023

Muscari, C. (author), Schito, Paolo (author), Viré, A.C. (author), Zasso, Alberto (author), van Wingerden, J.W. (author)In this work, we find a reduced-order model for the wake of a wind turbine controlled with dynamic induction control. We use a physics-informed dynamic mode decomposition algorithm to reduce the model complexity in a way such that the physics of the wake mixing can be investigated and that the model itself can be easily embedded into control...journal article 2023

van Hagen, L.J.A. (author), Petrick, Kristian (author), Wilhelm, Stefan (author), Schmehl, R. (author)A key motivation for airborne wind energy is its potential to reduce the amount of material required for the generation of renewable energy. On the other hand, the materials used for airborne systems’ components are generally linked to higher environmental impacts. This study presents comparative life-cycle analyses for future multi-megawatt...journal article 2023

van den Broek, M.J. (author), van den Berg, D.G. (author), Sanderse, Benjamin (author), van Wingerden, J.W. (author)Dynamic induction control is a wind farm flow control strategy that utilises wind turbine thrust variations to accelerate breakdown of the aerodynamic wake and improve downstream turbine performance. However, when floating wind turbines are considered, additional dynamics and challenges appear that make optimal control difficult. In this work...journal article 2023

Gonzalez Silva, J. (author), Ferrari, Riccardo M.G. (author), van Wingerden, J.W. (author)As renewable energy sources such as wind farms become dominant, new challenges emerge for operating and controlling them. Traditionally, wind farm control aims to dispatch power set-points to individual turbines to maximize energy extraction and, thus, their usage as assets. Yet, grid balance and frequency support are fundamental in presence...journal article 2023

Liu, Zhihao (author), Zhou, Jianfeng (author), Reniers, G.L.L.M.E. (author)In order to identify and clarify the association between the factors leading to accidents in a petrochemical tank area, this study analyzes investigation reports of 212 petrochemical tank farm accidents and combines this with the “association rule” mining and science related to complex networks. The main risk factors are determined and a risk...journal article 2023

Intriago Zambrano, J.C. (author), Diehl, J.C. (author), Ertsen, M.W. (author)Smallholder farmers (SFs) are cornerstone actors in eradicating poverty and hunger. Companies have recently focused on SFs as potential customers and suppliers. Several hindrances yet prevent SFs to be commercially viable actors. In this respect, sustainable business models (SBMs) bring opportunities for companies to increase profit, improve...journal article 2023

Liu, Tianzhu (author), Korthals Altes, W.K. (author), Melot, Romain (author), Wallet, Frédéric (author)The reterritorialisation of agricultural activities (RAA) consists of reinforcing local food production and its diversification activities oriented toward local consumers. RAA helps shape the local food system, which is an increasingly studied topic in the planning field. However, institutional impacts on planning approaches for RAA remain...journal article 2023

Frederik, J.A. (author), van Wingerden, J.W. (author)In recent studies, the effectiveness of different so-called wake mixing strategies has been assessed in terms of wind farm power maximization. These studies show that by dynamically varying the pitch angles of a wind turbine, wake mixing can be enhanced to increase the overall power production of a wind farm. However, such strategies also...journal article 2022
