Abstract
Generator control has been studied using various methods. Generator control is an effective way to improve the stability and reliability of power systems which are continually expanding and becoming more compli-cated. However, the comparative estimation of these control methods is not made using one common criterion. In this paper, three kinds of fundamental generator control methods, optimal control, fuzzy control and PID cuntrol, are considered with some proposed alterations and a uniform evaluation of these control methods is made quantitatively with consideration for practical use. From the simulation results, a uniform evaluation is obtained by using a one-machine infinite-bus system which includes AVR and governor as the control object model.
