Research on dynamic layout optimization of micro site selection for floating offshore wind farm
Given that existing micro-siting methods for offshore wind farms seldom consider the displacement of floating wind turbines due to wind and wave effects,this article proposes a micro-siting optimization method for floating wind farms that takes into account the displacement of the mooring system.This method employs an improved grid enumera-tion optimization algorithm to obtain the static optimal layout of floating wind turbines.Based on this,it considers the impact of mooring system displacement,introduces a quasi-static mooring model to calculate the displacement of each wind turbine,and aims to maximize the power generation of the wind farm as the optimization objective,achieving dy-namic optimization of floating wind turbines.Ultimately,this method facilitates the rapid generation of a floating wind turbine arrangement plan that meets optimization objectives and constraints.Finally,a case study is conducted on a wind farm in a certain sea area in the eastern South China Sea.The results show that compared to the static layout,the dynamic layout under various wake flows has varying degrees of power generation improvement,which can be applied to practical engineering for micro-siting layout of offshore floating wind farms.
