Assessing Power System Stability Following Load Changes and Considering Uncertainty

D. V. Ngo, K. V. Pham, D. D. Le, K. H. Le, K. V. Huynh


An increase in load capacity during the operation of a power system usually causes voltage drop and leads to system instability, so it is necessary to monitor the effect of load changes. This article presents a method of assessing the power system stability according to the load node capacity considering uncertainty factors in the system. The proposed approach can be applied to large-scale power systems for voltage stability assessment in real-time.
