Fixed Cost Allocation Method of Offshore Wind Farm Integration System Considering Wind Power output Correlation

Abstract

With the large-scale and cluster development of offshore wind farms, it has become an inevitable trend for the development of offshore wind farm integration to form an intensive mode of interconnection of offshore power transmission network and land power network. Aiming at the problem of fixed cost allocation for offshore wind farm integration system under multi-stakeholder investment., this paper proposes a fixed cost allocation method for offshore wind farm integration system considering the correlation of wind power output. First, considering the correlation between wind speeds in offshore wind farms, the PSO is used to optimize the weight coefficient of the mixed Copula function, and a wind speed correlation model based on the mixed Copula function is established. Secondly, for the fixed cost allocation problem of the offshore wind farm integration system, the fixed cost allocation method based on the Shapley value solution of cooperative game is used to establish the cooperative game model of the fixed cost allocation of the offshore wind farm integration system. Taking the IEEE30 node standard test system as an case, the simulation results of the case verify the effectiveness and superiority of the proposed method.
