摘　　要：基于我国抽水蓄能电站存在投资成本回收压力大、社会投资意愿不强、与市场发展不够衔接等生存发展问题,设计抽水蓄能电站两部制电价市场衔接机制,并建立市场化模式下抽水蓄能全寿命周期效益评估模型,对抽水蓄能参与市场的利润空间进行测算。通过对容量电价与容量电费进行电站全寿命周期仿真,发现核定容量电价有下降的趋势并趋于平稳,容量电费呈“U”型变动趋势。研究结果表明设计的两部制电价市场衔接机制可以使抽水蓄能电站在电力市场中获得合理收益,阶梯式逐步降低核定容量电价覆盖电站容量的比重,帮助抽水蓄能电站较平稳地转换到独立市场主体的身份。To cope with such problems existed in pumped storage power stations in China as the pressure of investment cost recovery, the lack of social investment willingness and the lack of connection with market development, a two-part electricity price market connection mechanism of pumped storage power station was designed, in addition, a life cycle benefit evaluation model of pumped storage under the market-oriented mode was established to calculate the profit space of pumped storage participating in the market. By means of the life cycle period simulation of pumped storage power stations by capacity electric price and electrical capacity charge, it was found that the approved capacity electricity price existed a downward trend and this trend tended to be stable, and the capacity electricity charge emerged the U-shaped changing trend. Research results show that the designed two-part electricity price market connection mechanism can make the pumped storage power stations obtaining reasonable income in the electricity market and stepwisely reducing the proportion of the approved capacity electricity price covering the power station capacity to help the pumped storage power stations smoothly converted to the identity of an independent market subject.
