Abstract

This report aims to give a approach to the problem of voltage instability and collapse. The main symptoms of voltage collapse are- low voltage profile, heavy reactive power flows, inadequate reactive support, and heavily loaded system. The collapse is often cause by low-probability single or multiple contingencies. The consequences of collapse often require long system restoration, while large groups of customers are left without supply for extended period of time. Voltage stability analysis methods such as the PV - analysis, and in particular the QV-analysis, will be used along with simulations in order to determine the test system proximity to a system voltage collapse. All the simulations are to be done with a constant load model, in other words, a static model is assumed throughout the simulations. The software used to do the simulations is Power World Simulator.
