Study on integrated development and hybrid operation mode of nuclear power plant and pumped-storage power station

Abstract

The nuclear power plant is suitable for base-load operation, while the pumped-storage unit mainly gives play to capacity benefit in the electric power system; hence, the integrated development and hybrid operation mode of the two can better meet the needs of the electric power system. This article first presents an analysis of the necessity and superiority of such mode, then explains its meaning and analyzes the working routes. Finally, it proposes the business modes as follows: low price pumping water electricity plus nuclear power in the near term; nuclear power shifted to pumped storage power participating in market competition in the middle term; and, in the long term, nuclear power shifted to pumped storage power as primary and serving as an electric power system when needed.
