From laggard to leader: explaining offshore wind developments in the UK [PDF]

, 2013
Offshore wind technology has recently undergone rapid deployment in the UK. And yet, up until recently, the UK was considered a laggard in terms of deploying renewable energy. How can this burst of offshore wind activity be explained?

Wind Energy Potential in Gaza Strip-Palestine state

Solar Energy and Sustainable Development journal, 2021
In this study, wind speed and direction data provided by Meteoblue AG-Switzerland as hourly time-series for 16 years from 2000 to 2015 for selected three cities in Gaza Strip, are used directly to evaluate the wind energy in the three selected sites ...

Low-level jets in the North and Baltic seas: mesoscale model sensitivity and climatology using WRF V4.2.1 [PDF]

Geoscientific Model Development
Low-level jets (LLJs), characterized by wind speed maxima in the lower part of the atmospheric boundary layer, play a crucial role in shaping wind resource availability, particularly as modern wind turbines reach heights exceeding 200 m.

Analysis of control-oriented wake modeling tools using lidar field results [PDF]

Wind Energy Science, 2018
The objective of this paper is to compare field data from a scanning lidar mounted on a turbine to control-oriented wind turbine wake models. The measurements were taken from the turbine nacelle looking downstream at the turbine wake.

The Making of the New European Wind Atlas – Part 2: Production and evaluation [PDF]

Geoscientific Model Development, 2020
This is the second of two papers that document the creation of the New European Wind Atlas (NEWA). In Part 1, we described the sensitivity experiments and accompanying evaluation done to arrive at the final mesoscale model setup used to produce the ...

Bidding wind energy under uncertainty [PDF]

, 2007
The integration of wind energy into electricity markets implies that the wind energy must commit their production for a given time period. This requires the use of short term wind power prediction tools to prepare the bids for the spot market.

Streaming dynamic mode decomposition for short‐term forecasting in wind farms

Wind Energy, 2022
Forecasting in wind energy is a crucial task to perform adequate wind farm flow control or to participate in the energy market. While many power forecasting methods exist, it is notoriously difficult to capture both short‐ and long‐term variations in the

Stellar wind bubbles around WR and [WR] stars [PDF]

, 2002
We study the dynamics of stellar wind bubbles around hydrogen-deficient stars using numerical simulations with time- and ion dependent cooling. We consider two types of hydrogen-deficient stars, massive WR stars, producing Ring Nebulae, and low mass [WR]
