Derivation of Distribution Network Vulnerability Indicators Based on Voltage Stability

Abstract

Whether the voltage of the distribution network is stable or not, needs to be judged by indexes, and different analysis methods of voltage stability correspond to different analysis indexes. The chapter introduces the current analysis indexes of voltage stability, as well as the voltage index L. Based on the voltage index L of the existing two nodes system, the multinode system is extended to deduce the expression of voltage index L of the load node in the multinode system, and to put forward the fast calculation method to get the accurate value of index L.
