Abstract

The paper analyses the influence of new energy vehicles on the voltage stability of the power system after grid-connected charging, and introduces two voltage stability indexes (L index and VCPI index) that can intuitively reflect the voltage stability level of the power system. Based on the typical voltage stability test model of the power system, two sets of new energy vehicle loads are added for simulation analysis, and the voltage stability state of the important buses (including the charging buses) in the system under different load combinations is observed. Through the collection of data, the L index and the VCPI index were calculated, and the accuracy of the two indexes was compared and verified.
