Assessment and Enhancement of Static Voltage Stability With Inverter-Based Generators.

In this letter, a systematic static voltage stability index for evaluating system loading status in distribution networks is deduced from complex power flow models. The proposed index facilitates impact analysis on the integration of inverter-based distributed generators under different control modes, which may affect the static voltage stability. The case study, including various scenarios, is performed to validate the accuracy of the theoretical results. [ABSTRACT FROM AUTHOR]
