Abstract :
In recent years, methods for timely detection of areas close to voltage instability have been proposed, which, unlike conventional methods, have simpler and faster calculations based on the measurement of local voltage and current phases at bus or grid lines. But some of them do not work well in real networks, so in this article, we will compare the performance of two of these indices and finally show that the performance of the ZL / ZS index is better and more reliable than the Indicator index.
