Effects of limits in small signal stability analysis of power systems

Abstract:

This paper concentrates in demonstrating and analyzing the effects of limits on power system eigenvalue computations when system parameters change. A 3-bus system is used to illustrate and analyze the effect that limits and their modeling have on the system eigenvalues. The results obtained for the simple test system using a classical eigenvalue computational tool versus those obtained using a tool that adequately models the effects of limits on the eigenvalue computations are compared and discussed, based on time domain simulations to confirm the validity of the various results presented here.
