Abstract
This study introduces a novel methodology for optimizing Wave Energy Converter (WEC) positioning in an array using a continuous domain, surpassing the traditional fixed layout approaches. The Wave Energy Park Layout Assessment Index (WLA), which integrates the wave protection factor (HRA) and power absorption efficiency (q-factor), is employed to evaluate the performance of WEC farms. To enhance computational efficiency, unsupervised classification methods, such as k-means clustering, are used to reduce the number of sea states while accurately representing wave energy, preserving 90% of incoming wave energy. Genetic algorithms, integrating the SNL-SWAN hydrodynamic model, are then used to optimize WEC layout by balancing exploration and computational cost, maintaining solution diversity, and avoiding premature convergence. Compared to the non-optimized designs, the proposed method increases absorbed wave power by 87% and wave height reduction by 46%. The study acknowledges trade-offs between objectives and area restrictions, and provides an open-source code for further research and development in WEC farm optimization. This integrated approach aims to enhance the efficiency and effectiveness of WEC farm designs, offering a robust framework for future advancements in wave energy extraction.
