IMPACTS OF WIND POWER PLANT ON VOLTAGE STABILITY IN CASE STUDY OF QUANG TRI 110kV POWER GRID USING DIGSILENT SOFTWARE

Abstract

This paper focuses on analyzing voltage stability for the 110kV power
system in Quang Tri region through the PV and QV curve built by DIgSILENT
software. Based on this analysis, it is possible to identify weak nodes in voltage
stability corresponding to operating scenarios to propose necessary solutions to
improve voltage stability reserve at the nodes. Therefore, the article ensures high
science and practicality, in line with the current situation in Vietnam in general
and the Central region (Quang Tri) in particular.
