There are massive abandoned coalmines and corresponding underground space, which provides a viable solution to energy storage of renewable energy generation.
The construction of pumped storage power stations at abandoned mines or with mines as upper or lower reservoirs is clearly a new approach for the further development of PS power stations, and it supports the complete utilization of mine resources. The development and application prospects of this approach are very broad.
By combining the abandoned mine data, eight PS power stations with different parameters were selected for the optimal configuration study. The installed capacity of PS4 and PS5 is consistent with the standard PS mentioned above, but the rated head and adjustable storage capacity are inconsistent.
Based on the existing mine data, there are many abandoned mines that meet the requirements of PS station construction and operation. Different types of PS systems are selected to optimize the configuration at different types of mines. The specific PS parameters for mine transformation are shown in Table 13. Table 13.
Unless properly managed and developed, abandoned mines can create safety, environmental and social problems, including the risk of mine collapse, subsidence and the release of hazardous substances into the environment, as well as the loss of jobs and displacement of communities [20, 21].
The factors affecting the regulation ability of PS systems at mining pits are analysed, and three PSs, namely, 1200 MW PS 4, 1200 MW PS 5 and standard PS, are selected for horizontal analysis. The initial volumes of the upper reservoirs for standard PS, PS 4 and PS 5 are 7 million, 10 million, and 10 million cubic metres, respectively.
