The proposed MLE method is validated for the assessment of one of the vulnerable patterns of power systems: transient rotor-angle instability. The main idea is to calculate MLE along the system dynamic trajectory in order to predict a loss of synchronism of power systems. Observability of PMU-based power system analysis is studied with a purpose of developing a method to quantify how well the available PMU measurements can be used to monitor dynamics of a power system. The research results in an innovative application of PMU data. Once an unstable power swing is captured and rotor-angle instability is predicted by the above method, self-healing actions, such as power system partitioning control.
