Abstract: Aiming at the deficiency of large-scale premium wind resource in mid-east and south region of China,and frequent rationing of power supply in north area of China,this paper puts forward development and construction mode with the characteristics of miniaturization,decentralization,intelligence and specialization in wind power project.Firstly,ten key indices are selected,which affect the decision-making of construction and the evaluation model of decision-making is built.Based on the theory of bilayer interactive finite rational decision,and the idea of miniaturization,decentralization,intelligence and specialization is utilized to optimize the indices of design scheme,which acquires as construction scheme that satisfies the decision maker.Finally,by taking construction decision of a wind farm in a certain area as an example,the practicability is verified and provides a new scheme for distributed wind power.
