A Conception of a New Generation of Pumped Storage Power Station with Multiple Energy Coupling

This paper proposes a new type of pumped storage power station, a new generation of pumped storage power station that combines the multiple energy coupling of variable speed unit technology, chemical energy storage system, wind energy, solar energy and other new energy storage systems. The advantages of variable speed pumping technology, better stability, greater adjustment range and reactive power compensation capability are introduced in detail. The addition of mature energy storage technology has enabled the power station to respond to faults with a speed of up to milliseconds. New energy sources such as light work together to build a green pumped storage power station. Based on the in-depth analysis of the characteristics of the new pumping station, three areas of the new generation of pumped storage power stations are proposed in the load concentration area, the new energy concentration area and the ultra-high voltage (UHV) drop-end concentration area, respectively. The reconstruction of Mount Langya Pumped Storage Power Station in Anhui power grid is taken as an example in paper. The new generation of pumped storage power station with multiple energy interaction and synergistic complementation can greatly enhance the comprehensive performance of traditional power station.
