Data-driven multivariate wind turbine performance modeling: Refining wind turbine performance estimations for atmospheric conditions by using machine learning

Traditionally a wind turbine’s power curve is used to model the long-term energy yield of the wind turbine and afterwards assess the performance of the turbine (power curve verification). But the current power curve is typically univariate: only dependent on the wind speed and slightly adjusted for site density, turbulence intensity and wind...

Using polynomial chaos expansion for wind energy

Surrogate models are used to approximate the expensive ‘true’ simulation codes and thus have the potential to speed up the wind farm layout optimisation problem (WFLOP). One technique to make surrogate models is Polynomial Chaos Expansion (PCE). PCE can approximate a (wind farm) model by using orthogonal polynomials which are constructed based...

Simulating Frontal Low Level Jets and Quantifying their Impact on Wind Energy Production

Wind energy is becoming an important source of energy and reliable forecasts for the production of wind energy are needed to improve its integration in the power grid. The increasing height of wind turbines results in higher layers of the atmosphere being reached, where other phenomena than the surface-based ones can be of importance. One of...

Techno-economic assessment of grid connected Power to Heat and Power to Hydrogen technologies: An electricity market scenario approach

Wind energy is the most promising renewable energy source for the Netherlands in the energy transition period. However, the investment costs of the offshore wind are huge. Until now, the government was supporting the investments in wind farms with subsidy schemes irrespective of the electricity market dynamics. The latest large-scale offshore...

Greedy Wind Farm Layout Optimization Using Pre-Averaged Losses

Wind turbine placement in a wind farm can be optimized to limit power losses due to wakes and improve the economic value of the plant. Seeing as wind farms are increasing in number and size, fast methods to generate good quality layouts can be beneficial for designers. Wind Farm Layout Optimization (WFLO) consists in finding a layout that...

An analysis on wind farm design: The comparison between manual and computed design

Wind farms are increasing in size to keep up with the increased demand for renewable energy. Larger wind farms, leads to more complex wind farm design problems for a designer. This study investigates the wind farm design process and compares computed and manual design approaches in order to find the best solution to the wind farm layout...
