Abstract

As international efforts to address climate change grow, an increasing number of countries and companies have put forward a clear “net zero” goal through accelerated renewable-energy development. As a renewable energy source, offshore wind energy has received particular attention from many countries and is a highly active research area. However, the design of offshore wind turbine structures faces challenges due to the large and complex design parameter space as well as different operational requirements and environmental conditions. Advanced optimization technology must be employed to address these challenges. Using an efficient optimization algorithm, it is possible to obtain optimized parameters for offshore wind turbine structures, balancing energy generation performance and the life of the floating wind turbine. This paper presents a review of the types and fundamental principles of several critical optimization technologies along with their application in the design process, with a focus on offshore wind turbine structures. It concludes with a discussion of the future prospects of optimization technology in offshore wind research.

Highlights

  • With the rapid growth of global energy, climate change and ecological and environmental issues are increasingly concerning

  • For the design optimization of offshore wind turbines, based on a coupled parametric finite-element analysis (FEA) and genetic algorithm (GA), the study by Gentils et al [64] minimized the mass of the support structure under multicriteria constraints for a 5 MW offshore wind turbine on an OC3 monopile

  • Optimized a full lattice tower using sequential quadratic programming (SQP) in the frequency domain, where static design was obtained from extreme load analysis followed by a redesign of member thickness against the fatigue loads

Summary

Introduction

With the rapid growth of global energy, climate change and ecological and environmental issues are increasingly concerning. Most existing shallow offshore wind farms use this kind of foundation This structure is restricted by geological conditions and water depth. For large water depths and a soft seabed, floating wind turbines (FWTs) are generally more cost-effective, as the overall cost only marginally increases with the additional length of mooring lines. Because they are installed far from the shore, they are less restricted by size, noise, scenery, and other regulations. Henderson et al [3] discussed the advantages of utilizing floating foundations and outlined the technical challenges for different types They provided a detailed overview of the potential new markets for FWT technology.
