Abstract Firstly, this paper makes a preliminary analysis of the structure of a typical offshore high-voltage full DC wind farm. Focusing on the comparative study of the series-parallel structure and the new hybrid matrix structure, the dynamic cost-benefit analysis model of the two structures is established by theoretical derivation, with the cost-benefit as the core and considering the reliability. The economic advantages and disadvantages of the two structures are quantitatively compared in detail, and it is concluded that the economy of the full DC wind farm based on the hybrid matrix structure is better than the series parallel structure.

Key words： offshore wind farm full DC convergence economy hybrid matrix structure series- parallel structure cost-benefit analysis model
