Abstract

This paper presents an economic assessment of the integration of battery energy storage systems for providing frequency regulation reserves in island power systems that are undergoing a transition to a decarbonized energy mix. The Dominican Republic system is used as a paradigmatic case study. The study employs actual data from 2022 and multiple mixed-integer linear programming optimization models to evaluate the operational and frequency regulation provision costs in different scenarios, both with and without accounting for the contribution of the storage systems to primary and secondary frequency regulation. The findings indicate that the integration of battery energy storage systems can lead to a reduction in annual operational costs of 10%, and enhance the penetration of renewable energy by 12% for 2030. Moreover, the economic analysis reveals that currently, the payback period for such investments is less than one year for primary frequency regulation and less than two years for secondary frequency regulation. The results highlight the dual benefits of storage systems in enhancing grid stability and supporting the integration of renewable energy, thus contributing to a more sustainable and resilient power system.

用于频率调节储备供应的电池储能系统的经济评估：以多米尼加共和国为例

本文提出了电池储能系统集成的经济评估，为正在向脱碳能源组合过渡的岛屿电力系统提供频率调节储备。多米尼加共和国的系统被用作一个范例案例研究。该研究采用2022年的实际数据和多个混合整数线性规划优化模型，在考虑和不考虑存储系统对一次和二次频率调节的贡献的情况下，评估不同情景下的运行和频率调节提供成本。研究结果表明，电池储能系统的整合可以使年运营成本降低10%，并在2030年将可再生能源的渗透率提高12%。经济分析表明，目前该类投资一次调频的投资回收期不足一年，二次调频的投资回收期不足两年。研究结果强调了储能系统在提高电网稳定性和支持可再生能源整合方面的双重效益，从而有助于建立一个更具可持续性和弹性的电力系统。
