Abstract :
A 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. It provides an analytical basis for establishing critical capacitor and load switching times. These issues are considered
