论文摘要
本文评估AC系统的频率性能是由位于遥控区域的基于逆变器的资源提供的。由于潜在的较大的波传播常数在较长的线上，因此基于逆变器的资源的快速积极功率响应可能会对系统频率响应产生负面影响。在此上下文中，本文介绍了一个控制性能分析，以确定在远程位置的基于逆变器的资源使用本地频率测量值时，以确定改善频率稳定性的局限性。我们的结果表明，在分配初级频率控制时，在干扰排斥和稳定性之间存在一个trafeoff。特别是，快速频率控制可能会对阻尼不良的机电模式的阻尼比产生负面影响。
This paper evaluates the frequency performance of an AC system when primary frequency response is provided by inverter-based resources located at remote-areas. Due to potentially larger wave propagation constants over longer lines, fast active power response from inverter based resources may have a negative impact on the system frequency response. Within this context, this paper presents a control performance analysis is presented in order to identify limitations for improving the frequency stability when inverter-based resources in remote locations use local frequency measurements. Our results suggest that there exists a trafeoff between disturbance rejection and stability robustness when allocating primary frequency control. In particular, fast frequency control can have a negative impact on the damping ratio of poorly damped electromechanical modes.
