Wake Effect Mitigation of Floating Offshore Wind Farms: Combining Layout Optimization, Turbine Repositioning and Yaw-based Wake Redirection

Floating wind turbines despite the the potential to harness energy from deep offshore areas where higher average wind speeds face challenges in terms of competitiveness. One approach to raising the competitiveness of a wind farm is to mitigate efficiency losses resulting from the wake effect. This report focuses on the combination of three...

Hybrid truss layout optimization for generating multiple design alternatives

As of writing this thesis little research has been done in truss layout optimization for multiple design alternatives. A hybrid scheme is proposed in which the fast gradient-based search of the Ground Structure Method (GSM) is employed for the search of optimal topology and size, while a population-based meta-heuristic algorithm explores the non...

Offshore Wind Farm Optimisation: A Comparison of Performance between Regular and Irregular Wind Turbine Layouts

Wind farm layouts in industry show a range of patterns with an overall trend from regular to irregular patterns over time. Wind farm layout optimisation studies in literature generally result in irregular wind turbine patterns. Review of existing literature shows that the performance of irregular and regular wind farm layouts has not been...

Energy Space Layout: Designing space layout with optimised energy performance

The current housing market in the Netherlands depicts a need for energy-efficient buildings for young professionals. Performative Computational Architecture (PCA), as computational methodology, is a valuable source of knowledge and design support to integrate the buildings’ performances at early stages. By applying PCA, this thesis explores and...

David and the vegetable factory: A Two-stage Optimization Model for Generating a Vegetable Factory's Facility Layout Using the Gradient Descent Approach

In this thesis a two-stage model is proposed, combining the idea of a two-stage model from Anjos and Vieira [1] with a gradient descent approach, much like proposed in Sikaroudi and Shahanaghi [42], in order to solve the facility layout problem for problems consisting of 8 and 12 departments . This method was chosen after analyzing the criteria...

Layout Optimization Methods for Offshore Wind Farms Using Gaussian Processes

Surrogate modeling is a family of engineering techniques that attracts great interest today and can be applied in many challenging fields. A big advantage of it is that surrogate models (models based on these techniques) offer reliable results by being computationally cheaper than other candidate models. The savings in computational time is...
