With the growing demand for renewable energy and the increasing emphasis on environmental protection

large-scale offshore wind power has become an important part of the clean energy sector.How to efficiently and safely send out the power of offshore wind farms is the key to realizing its large-scale application.This paper focuses on the decision-making research of power delivery mode of large-scale offshore wind turbines in order to maximize the efficiency and reliability of wind power systems.Taking an offshore wind power cluster in the east coast as an example

this paper evaluates the economy and feasibility of various power transmission methods

such as DC transmission and AC transmission

considering the scale and layout of offshore wind farms.Finally

by comparing the comprehensive indicators of cost

reliability and environmental impact of different schemes

the corresponding power delivery method decision-making suggestions are put forward

which provides a useful reference for the sustainable development of large-scale offshore wind power.
