Economic Analysis of the Integrated Operation Mode of Nuclear Power Station and Pumped-storage Power Station

摘要

This paper proposes the integrated operation mode of nuclear power station and pumped-storage power station, and makes an intensive economic analysis of the integrated operation mode based on the position of investors. Firstly, this paper thoroughly discussed the calculation method of annual cost in two schemes: (a) investors only operate nuclear power station and pay peak load regulation compensation; (b) investors operate nuclear power station and pumped-storage power station jointly to participate in electricity network load adjustment. And cost comparison method was used to compare the economy of two schemes. Secondly, this paper took a nuclear power investor's two operation schemes as an example, and compared the annual cost of each scheme. Ultimately, the case study shows that: the annual cost of integrated operation mode is lower than the annual cost of peak load regulation compensation borne by nuclear power investor, that is to say, the integrated operation mode of nuclear power station and pumped-storage power station is more economical.
