Abstract

As the proportion of new and renewable energy increases, power control demands are becoming more frequent due to variability in power generation. As a complementary means against this, the pumped storage hydropower plants (PSHP) are attracting attention as energy storage systems (ESS), but it has high construction costs. Therefore, this study aims to improve the economic feasibility by developing the evaluation model of the existing infrastructure into an upper/lower dam suitable for PSHP. The concept of upper dam capacity is newly defined, and the evaluation index is constructed using normalization. A new evaluation system is presented for five factors: environment, stability, energy, capacity, and economy. Finally, it is tested in the pilot area in Korea. Several candidates, including the PSHP in operation, are found to have been distributed with higher scores. These results will help to satisfy the selection of candidates during the preliminary feasibility study phase, and programming them will enable more accurate and rapid assessment.

基于评分的现有抽水蓄能水电站修复建设评估模型

随着新能源和可再生能源比例的增加，由于发电的不稳定性，对电力控制的要求也越来越频繁。作为补充手段，抽水蓄能水电站（PSHP）作为储能系统（ESS）备受关注，但其建设成本较高。因此，本研究旨在通过将现有基础设施开发成适合 PSHP 的上/下坝评估模型来提高经济可行性。新定义了上坝容量的概念，并采用归一化方法构建了评价指标。针对环境、稳定性、能源、容量和经济性五个因素提出了新的评价体系。最后，在韩国试点地区进行了测试。结果发现，包括运行中的 PSHP 在内的几个候选方案的分布得分都较高。这些结果将有助于满足初步可行性研究阶段对候选方案的选择，对候选方案进行编程将使评估更加准确和快速。
