Nonlinear Generator Control Based on Equilibrium Point Analysis for Standard One-Machine Infinite-Bus System Model

Abstract

The aim of this letter is to show that the unstable equilibrium point of the Japanese standard one-machine infinite-bus system model is eliminated by adding a simple nonlinear complementary control input to the AVR, and then the critical clearing time of the system can be more enhanced in comparison with the PSS by introducing the proposed nonlinear generator control.
