Lyapunov Functions Family Approach to Transient Stability Assessment [PDF]

IEEE Transactions on Power Systems, 2016
Analysis of transient stability of strongly nonlinear post-fault dynamics is one of the most computationally challenging parts of Dynamic Security Assessment. This paper proposes a novel approach for assessment of transient stability of the system. The approach generalizes the idea of energy methods, and extends the concept of energy function to a more
