论文摘要
本文介绍了大型互连电源系统的动态频率调节（FR）模型，包括储能系统（ESS），例如电池能量存储系统（BESS）和飞轮储能系统（FESSS），考虑了频率控制过程中的所有相关阶段。在FR控制循环和ESS中的信号传输时，考虑了沟通延迟，并且考虑了它们的负责状态（SOC）管理模型。系统，ESS和SOC组件从FR的角度详细建模。基于北美东部互连（NAEI）的实用瞬态稳定模型（NAEI）的实用瞬态稳定性模型对该模型进行了验证，结果表明，所提出的模型准确地代表了包括ESS在内的大型互连电力网络的FR过程，并且可以用于长期FR研究。还研究和讨论了ESS设施在区域控制错误（ACE）中的沟通延迟和SOC管理的影响
This paper presents a dynamic Frequency Regulation (FR) model of a large interconnected power system including Energy Storage Systems (ESSs) such as Battery Energy Storage Systems (BESSs) and Flywheel Energy Storage Systems (FESSs), considering all relevant stages in the frequency control process. Communication delays are considered in the transmission of the signals in the FR control loop and ESSs, and their State of Charge (SoC) management model is considered. The system, ESSs and SoC components are modelled in detail from a FR perspective. The model is validated using real system and ESSs data, based on a practical transient stability model of the North American Eastern Interconnection (NAEI), and the results show that the proposed model accurately represents the FR process of a large interconnected power network including ESS, and can be used for long-term FR studies. The impact of communication delays and SoC management of ESS facilities in the Area Control Error (ACE) is also studied and discussed
