摘　　要：为了实现“双碳”战略,国家正逐步采取措施降低燃煤火电比重,增加清洁能源太阳能和风能等的使用。近些年由于可再生能源的时空不确定性和大型储能设施的匮乏,弃风弃电弃光现象愈演愈烈。为了提高风能和太阳能的利用率,提出在太阳能风能富集地区利用废弃煤矿采空区作为地下抽水蓄能水库,以促进可再生能源的转储并用。论文从采空区最大库容、可用库容和气液交换等方面分析了采空区作为抽水蓄能地下水库的储存能力,并结合我国典型废弃煤矿采空区特点和相关气象数据,分析了拟建采空区地下水库的储能系统的能量和库容变化特征。综合分析得出结论:在风能和太阳能丰富的中国西北和西南地区,利用废弃煤矿采空区开发抽水蓄能电厂在技术上是可行的。In order to realize the"Double Carbon"strategy,the state is gradually taking measures to reduce the proportion of coal-fired thermal power and increase the use of clean energy such as solar energy and wind energy.In recent years,due to the temporal and spatial uncertainty of renewable energy and the lack of large-scale energy storage facilities,the phenomenon of abandoning wind and power(abandonment of light)is becoming more and more serious.In order to improve the utilization rate of wind and solar energy,it is proposed to use abandoned coal mine goafs as an underground large-scale pumped hydro storage reservoir in areas rich in solar and wind energy to promote the combined use of available energy.The storage capacity of the goaf as a large-scale pumped hydro storage reservoir is analyzed from the aspects of storage capacity,usable capacity and gas-liquid exchange in the goaf.Combined with the characteristics of goaf and related meteorological characteristics of typical abandoned coal mines in China,the energy storage characteristics of underground reservoirs in goaf are analyzed.It has been found that using abandoned coal mine goafs to develop pumped hydro storage plants is technically feasible in wind and solar-rich northwestern and southwestern China.
