论文摘要
基于逆变器的资源（IBR）在当前电力系统上的优势已广泛研究。可再生能源渗透的这种增加引起了人们对现有电网稳定性的一些担忧。从历史上看，功率系统由同步发电机主导，由于惯性高和阻尼特性，可以轻松地对系统不稳定性反应。但是，借助IBR，逆变器的控制在有助于系统稳定性和增强逆变器功能方面起着至关重要的作用。这些新型控制方法之一是下垂控制。下垂特性用于控制电压，频率以及主动和反应能力。本文介绍了频率下垂阻尼对系统频率，实际功率以及通过分布式能源资源的频率变化速率的影响。另外，根据结果建议电池尺寸。结果还表明，在成本和性能方面，需要最佳选择频率下垂阻尼以满足适当的电池大小。模拟是在电磁瞬态程序（EMTP）中进行的
Inverter-based resources (IBR) have been widely studied for their advantages on the current power systems. This increase in the penetration of renewable energy has raised some concerns about the stability of the existing grid. Historically, power systems are dominated by synchronous generators that can easily react to system instability due to high inertia and damping characteristics. However, with IBR, the control of the inverter plays a crucial role in contributing to the system stability and enhancing the functionality of the inverters. One of these novel control methods is droop control. Droop characteristics are used to control voltage, frequency, and active and reactive power. This paper presents the impact of frequency droop damping on system frequency, real power, and the rate of change of frequency with distributed energy resources. Also, battery sizing is suggested based on the results. The results also show the need for optimal selection for the frequency droop damping to fulfill the appropriate battery size in terms of cost and performance. The simulations are carried out in an electromagnetic transient program (EMTP)
