In recent years

the scale of wind power is growing rapidly

its economic analysis and cost modeling methods are also constantly improving. In order to summarize the existing methods and clarify the follow-up research ideas

the four stages of the whole life cycle of the wind power project are first explained. Then

the cost composition and modeling method of the whole life cycle of wind power projects are introduced

and the differences between onshore and offshore wind farms in this part are compared

and the relationship between life cycle and investment cost is discussed based on the above contents. In order to introduce the benefits of cost investment

the basic economic evaluation indexes and applicability of wind power projects are compared. On this basis

the future development trend is analyzed according to the existing problems

and some suggestions are put forward for the economic evaluation of wind power in different regions and environments. It is hoped that the work of this paper can provide reference for wind power cost modeling and economic evaluation under the new development trend.
