论文摘要
本文为低阶系统频率响应(SFR)模型提供了一种新颖的闭合解决方案,该解决方案在所有时间段中都是准确的,并且伴随近似值,用于以两个不同的速度表示初级频率响应,同时仍保持数学障碍性。这允许在单个SFR公式中包括快速频率响应(例如,来自电池储能系统)和更多常规响应(例如,从热产生中)。封闭式表达式可以有效地用于使用SFR模型的应用中,例如频率稳定性研究和安全受限的单位承诺(SCUC)研究。
This paper presents a novel closed-form solution for a low-order system frequency response (SFR) model that is accurate for all time periods and an accompanying approximation for representing primary frequency responses at two different speeds while still maintaining mathematical tractability. This allows for the inclusion of both fast frequency responses (e.g. from battery energy storage systems) and more conventional responses (e.g. from thermal generation) in a single SFR formulation. The closed-form expressions can be efficiently used in applications that use the SFR model such as frequency stability studies and security-constrained unit commitment (SCUC) studies.
