In the context of large-scale development and clustering integration of offshore wind power,fairly and eq-uitably recovering the transmission costs of offshore wind power integration systems and allocating them to wind farms has become a pressing issue in the offshore wind power industry.To address this challenge,a method for allo-cating fixed costs in offshore wind power integration systems,taking into account the correlation of wind power out-put,is proposed.Firstly,the Vine copula function is employed to construct a correlation model for the output of mul-tiple offshore wind farms.Additionally,it is assumed that the system's load demand model follows a normal distribu-tion,and the generators follow a[0,1]probability distribution.Then,using a combination of Monte Carlo sampling and the probability flow power flow tracking method,the fixed cost allocation for each integrated offshore wind farm is calculated.Finally,through case simulation analysis,the reasonableness and effectiveness of the proposed method are validated.
