Lyapunov Functions for Multimachine Power Systems with Dynamic Loads
This paper develops Lyapunov functions for power systems which have dynamic reactive power loads. These functions are extensions of earlier Lyapunov functions derived for structure preserving power system models having static loads. In order to obtain strict Lyapunov functions, the transient response of the dynamic load must have a logarithmic dependence on voltage. A Lyapunov function is initi...
متن کاملLyapunov Function Analysis of Power Systems with Dynamic Loads
A recently developed Lyapunov (energy) function incorporates both generator and load dynamics. This paper reviews that energy function. Its use in the assessment of the stability of power systems where generator and load dynamics are active is presented. Further, generator/load interaction is explored. This new energy function allows for direct assessment of (dynamic) voltage collapse scenarios...

متن کاملDynamic Lyapunov functions
Lyapunov functions are a fundamental tool to investigate stability properties of equilibrium points of linear and nonlinear systems. The existence of Lyapunov functions for asymptotically stable equilibrium points is guaranteed by converse Lyapunov theorems. Nevertheless the actual computation (of the analytic expression) of the function may be difficult. Herein we propose an approach to avoid ...
متن کاملDynamic Stability Analysis of Photovoltaic Systems using Lyapunov Functions
This paper proposes a novel approach based on Lyapunov function method to analyse the stability of photovoltaic (PV) systems. The Lyapunov function is formulated using the method of quadratic forms, i.e., Krasovskii’s method. The stability of the photovoltaic systems under different operating conditions is analysed based on the formulated Lyapunov function. A comparison of stability analysis us...
