With the increasing scale of wind power

the transmission capacity limits of the existing power grid will result in a large area of wind curtailment

and the effective way to solve this problem is to build wind power delivery channel. So the transmission capacity planning of wind power delivery is an important research topic. Through constructing the economic evaluation model of transmission projects

the planning method for transmission capacity of wind power delivery is proposed based on wind power distribution characteristics and the economy of transmission projects. Finally

taking an actual power grid system for example

the proposed method is verified

which can reduce the investment cost of transmission projects and can effectively increase the economic benefits of transmission projects.
