Time dependence of controls to avoid voltage collapse. IEEE Transactions on Power Systems, 15(4), 1367–1375. https://doi.org/10.1109/59.898114In this paper, the effect of time dependence of control actions used to avoid voltage collapse, such as reactive power compensation and load shedding, is studied. A thorough justification of the phenomena under study is first presented with the help of a simple test system. The time dependence of the control actions is then studied in a real voltage collapse scenario of the Chilean Interconnected System (CIS), based on a reduced system model.enpower system controlvoltage stabilityvoltage collapsereactive power compensationload sheddingArticle10.1109/59.898114
