电压稳定在电力系统稳定的各种分类中被认为是电力系统稳定研究的重要课题之一。经历扰动的电力系统有电压不稳定的危险。造成电压不稳定的主要原因是大扰动电压稳定下的线路突发事件导致各位置无功功率的凹陷。本文的目的是在N-1偶发情况下，确定互联电力系统中统一潮流控制器的最优位置。由于FACTS设备的尺寸和成本很高，因此必须在实际安装之前确定最佳位置和尺寸。我们尝试使用统一潮流控制器改善电压分布和最大负载参数，同时基于Cat群算法确定其最优位置。(C) 2013 Elsevier Ltd.版权所有。
Voltage stability categorized under various classifications of power system stability is considered one of the important subjects in power systems stability studies. A power system, experiencing disturbances, is at risks of voltage instability. Main reason for the cause of voltage instability is the sag in reactive power at various locations due to circuit contingencies classified under large disturbance voltage stability. The aim of this paper is to identify the optimal location of Unified Power Flow Controller in an interconnected power system under N-1 contingency. As the size and the cost of the FACTS devices are high, an optimal location and size has to be identified before they are actually installed. We are trying to improve the voltage profile and Maximum Loading Parameter using Unified Power Flow Controller while determining their optimal location based upon Cat Swarm Optimization.
