Abstract

Voltage Collapse is instability of a heavily loaded electric power system, which leads to declining voltages and blackout, and it is typically associated with reactive power limitations of the power system. Therefore, knowledge of the critical loading point is vital to ensure a secure mode of operation for the power system. Over the years, different methods were proposed in the literature to identify proximity to voltage collapse. However, these techniques were derived utilizing only the voltage limitation of the load buses. Voltage collapse is often interlinked with static transfer stability limit. In this work, different voltage collapse modes are addressed and a new algorithm that takes into account both load bus voltage and generator bus angle behavior is proposed to estimate the collapse point. The proposed method was examined on several IEEE test systems. Also, superiority of the proposed method in comparison with the other techniques was proven.
