Research on development demand and potential of pumped storage power plants combined with abandoned mines in China

摘要

To address the problem of unstable large-scale supply of China's renewable energy, the proposal and accelerated growth of new power systems has promoted the construction and development of pumped storage power plants (PSPPs), and the site selection of conventional PSPPs poses a challenge that needs to be addressed urgently. At the same time, in the process of reducing the share of coal energy, a great number of abandoned mines and resource-exhausted cities or regions have been formed. This study provides a detailed review of China's latest developments in PSPPs, including the current status of conventional PSPP projects, models, and the application potential of pumped storage in abandoned mine (PSAM). The application of conventional PSPPs is reviewed in terms of renewable energy storage demand of PSPPs in the light of China's energy structure. According to a summary of the PSPP models using abandoned mines, the application of PSAM is analyzed, and the combination of pumped storage and abandoned mine demonstrates considerable social and environmental benefits.
