Voltage Stability
Small Disturbance Voltage Collapse. At constant frequency (e.g., 60 Hz) the complex power transferred down a transmission line is S=VI*. V is phasor voltage, I is phasor current. This is the reason for using a high voltage grid. Line real power losses are given by RI2 and reactive power losses by XI2.

Hybrid Energy Storage System for Voltage Stability in a DC …
In renewable based DC microgrids, energy storage devices are implemented to compensate for the generation-load power mismatch. Usually, Battery Energy Storage Systems (BESS) are used, but they cannot meet the transient load demand due to low power density leading to voltage fluctuations. For this reason, Supercapacitor Storage …

Voltage Stability
6.3.2 Voltage stability. Voltage stability is described as a capability of a power system to maintain steady voltage at each bus after disturbances, and it is related to the ability to supply power to load. According to time scales, it can be divided into short-term voltage stability and long-term voltage stability.
