With the extensive integration of high-penetration renewable energy resources, more fast-response frequency regulation (FR) providers are required to eliminate the impact of uncertainties from loads and distributed generators (DGs) on system security and stability. As a high-quality FR resource, community integrated energy station (CIES) can effectively respond to frequency deviation caused by renewable energy generation, helping to solve the frequency problem of power system. This paper proposes an optimal planning model of CIES considering FR service. First, the model of FR service is established to unify the time scale of FR service and economic operation. Then, an optimal planning model of CIES considering FR service is proposed, with which the revenue of participating in the FR service is obtained under market mechanism. The flexible electricity pricing model is introduced to flatten the peak tie-line power of CIES. Case studies are conducted to analyze the annual cost and the revenue of CIES participating in FR service, which suggest that providing ancillary services can bring potential revenue.

考虑频率调节服务的社区综合能源站优化规划

随着高渗透性可再生能源的广泛集成，需要更多的快速响应频率调节（FR）提供商来消除负载和分布式发电机（DG）的不确定性对系统安全性和稳定性的影响。社区综合能源站（CIES）作为一种优质的阻燃资源，可以有效应对可再生能源发电引起的频率偏差，有助于解决电力系统的频率问题。本文提出了一种考虑了FR服务的CIES最优规划模型。首先，建立了帧中继服务的模型，以统一帧中继服务的时标和经济运行。然后，提出了一种考虑了FR服务的CIES最优计划模型，利用市场机制获得了参与FR服务的收益。引入了灵活的电价模型以平整CIES的峰值联络线电力。通过案例研究来分析参与FR服务的CIES的年度成本和收入，这表明提供辅助服务可以带来潜在的收入。
