| 基于常规水电站进行混合抽蓄开发可以有效促进新能源消纳,保障多能互补系统并网发电。针对混合抽蓄开发需要,本文提出了一种基于全生命周期综合评价的混合抽蓄-风-光多能互补系统容量优化配置方法。首先提出了表征新能源出力及径流不确定性的组合情景生成方法；然后在多能互补系统多段线送出的模式下,构建了混合抽蓄-风-光多能互补系统短期协同运行优化模型；最后建立了混合抽蓄-风-光多能互补系统不同时间尺度评价指标体系,通过全生命周期综合评价进行最优容量配置决策。黄河上游尔多水电站的案例研究结果表明：配置混合抽蓄与水电站等容量的情况下,系统的最优容量配置为风电3000 MW、光伏1500 MW,需配套送出通道容量3700 MW,此方案下的系统的净现值为158.6亿元。 |

| The integration of renewable energy development can be significantly enhanced by constructing pumped hydro storage plants （PHS） alongside conventional hydropower plants. This not only promotes the utilization of renewable energy but also ensures the stable operation of hybrid energy systems. In response to the development needs of PHS, this paper proposed a capacity optimization method tailored for hybrid PHS-wind-PV power system based on a comprehensive life cycle assessment. To characterize the uncertainties of renewable energy output and runoff, this paper introduced a scenario generation method for renewable energy output. Furthermore, a short-term coordinated operation optimization model was established specifically for the hybrid PHS-wind-PV power system, which operates under the mode of multi-segment transmission lines. In addition, a set of assessment indicators was developed that across different time scales for the hybrid system, and the capacity configuration decisions are based on a comprehensive life-cycle assessment. A case study of the Erduo Hydropower Station in the upper Yellow River shows that integrating hybrid pumped storage with equivalent hydropower capacity results in an optimal configuration of 3000 MW wind and 1500 MW PV power, necessitating a 3700 MW UHV transmission capacity, yielding in a net present value of 15.86 billion yuan. |
