A Framework for Robust Long-Term Voltage Stability of Distribution Systems by Nguyen, Hung D., Dvijotham, Krishnamurthy, Yu, Suhyoun, Turitsyn, Konstantin

“…IEEE Power injection uncertainties in distribution power grids, which are mostly induced by aggressive introduction of intermittent renewable sources, may drive the system away from normal operating regimes and potentially lead to the loss of long-term voltage stability (LTVS). Naturally, there is an ever increasing need for a tool for assessing the LTVS of a distribution system. …”
