Voltage reduction is one of the most common measures implemented to increase power reserves in emergency conditions. Since the power consumption of a composite load depends on the voltage, the power demand can be reduced by reducing the distribution voltage. Although the voltage reduction has a positive effect on power system in terms of securing reserve power, it may have a negative impact on the voltage stability in some conditions. Thus, it is necessary to analyze the effect of voltage reduction on the voltage stability. This paper analyzes the effect of voltage reduction on the voltage stability by performing PV analysis in various system conditions, such as base case on light load, heavy load, and contingency cases. In addition, we analyzed the effect of the voltage sensitivity characteristic of loads on the voltage stability.
