摘　　要：目前,抽水蓄能电站容量电价核定办法已通过两部制电价进一步完善,但缺少具体的电价实施细则,且尚未明确抽水蓄能电站配合新能源开发的价格分摊机制。为了解决抽水蓄能价格分摊机制和方式,以河西地区某抽水蓄能电站与新能源联合开发为切入点,采用“抽水蓄能电站+新能源电站”一体化开发方式,研究新能源不同弃电率、不同收益率情况下抽水蓄能电站带动的经济规模。结果表明:抽水蓄能与新能源联合开发的方式有利于抽水蓄能容量电价疏导,新能源规模为抽水蓄能规模的3~4倍时项目整体最为经济;河西地区新能源资源丰富,抽水蓄能供电甘肃电网的同时服务于新能源消纳,容量电价合理疏导方式为与当地新能源一体化开发,可优化资源配置、提升经济竞争力、共同获利,较为经济的抽水蓄能与新能源开发比例约为1∶3~1∶4。本研究可为新能源丰富地区后续核准、投运抽水蓄能电站的容量电费疏导途径提供思路,也为三北地区其他新能源基地配套抽水蓄能电站的合理规模提供参考。At present,the method for determining the capacity electricity price of pumped storage power stations has been further improved through a two-part electricity price system,but there is a lack of specific implementation rules for electricity prices,and the price sharing mechanism for pumped storage power stations to cooperate with new energy development has not been clearly defined.To resolve the price sharing mechanism and mode of pumped storage power stations,this study takes the joint development of a pumped storage power station and new energy power station in the Hexi region as the starting point,adopts the integrated development method of"pumped storage power station+new energy power station"and studies the economic scale driven by pumped storage power stations under different abandonment rates and returns of new energy.The study result shows that the joint development of pumped storage and new energy is beneficial for regulating the capacity price of pumped storage power station,and the overall project is the most economical when the capacity of new energy is 3~4 times of the pumped storage capacity.The Hexi region is rich in new energy resources,and pumped storage power supplies the Gansu power grid while serving the consumption of new energy.The reasonable way to divert capacity and electricity prices is to integrate with local new energy development,which can optimize resource allocation,enhance economic competitiveness,and jointly benefit all parties.The economical ratio of pumped storage to new energy development is about 1∶3 to 1∶4.This study provides ideas for the capacity price diversion modes for the subsequent approval and operation of pumped storage power stations in areas rich in new energy,and also provides reference for the reasonable scale of supporting pumped storage power stations in other new energy bases in the"Three North"region.
