Abstract：The availability of high-resolution, synchronized measurements from phasor measurement units (PMUs) presents an opportunity to develop advanced analytical techniques for power system dynamic performance. This work addresses practical issues for utilization of the theory of Maximum Lyapunov Exponent (MLE) along with Synchrophasor Technology. First, advanced models are applied to incorporate frequency variations of the loads and voltage control of the generators. Secondly, the algorithms are optimized such that the computational speed achieves a level promising for online application. Thirdly, a new formulation for implementing the MLE technique is proposed, which enables a fast and accurate detection and characterization of power system dynamics. The effectiveness of the proposed techniques is validated on a 537-bus Italian TERNA power system and a 15,000-bus PJM power system, with simulated and recorded PMU measurement data.
