In engineering construction, the accurate estimation of the investment cost can provide a reasonable basis for the formulation and decision-making of the construction scheme. In this paper, the wind-storage combined operation power station is taken as the research object, the investment cost estimation model is established, and the combined operation mode is analysed to obtain the annual power generation. Finally, according to the investment cost and annual power generation, the cost per unit of electricity model is established. In the past, wind farm and pumped storage power station are usually studied as two independent individuals, but in practical application, there are power conversion, regulation and control operations between them, which are interrelated and interactive. This paper regards the two as a whole and analyses their annual power generation under different cooperative operation modes. The research results of this paper can provide a theoretical basis for the preliminary cost estimation of engineering construction, so as to better determine the construction scheme of power plant.
