Abstract

Nowadays, for economic and environmental reasons, power systems usually work close to the limits of stability to make the most of existing networks. However, in such systems, sudden faults can cause severe instability between all equipment of the system. As a result, the voltage and frequency of the island system exceed the allowable limit. Due to this fact, voltage and frequency control is essential in the operation mode of the island. This paper investigates the effect of ramp rejecting electric power pre-filter stabilizer (RRPP) on voltage and frequency oscillations of a stand-alone network. It provides a taxonomy of the dynamic behavior of the system in various scenarios: no power system stabilizer (PSS), conventional PSS, and RRPP stabilizer. The accurate model of BESS and wind turbine is incorporated to cope with real conditions. Small signal analysis is used to evaluate and analyze the stability of the understudy network using the proposed method.
孤岛电网电压频率稳定性的增强
如今,出于经济和环境原因,电力系统通常在接近稳定极限的情况下工作,以充分利用现有网络。然而,在这样的系统中,突发故障会导致系统中所有设备之间的严重不稳定。因此,孤岛系统的电压和频率超过了允许的极限。由于这一事实,电压和频率控制是必不可少的岛的运行模式。研究了阻斜电力预滤波稳定器(RRPP)对独立电网电压和频率振荡的影响。它提供了系统在各种场景下动态行为的分类:无电力系统稳定器(PSS)、常规PSS和RRPP稳定器。结合BESS和风力机的精确模型,以适应实际情况。采用小信号分析方法对替补网络的稳定性进行评价和分析。
