Abstract

En 中文

This study presents an application of a fuzzy gain scheduled proportional and integral (FGPI) controller for load-frequency control of a two-area electrical interconnected power system. Model simulations of the power system show that the proposed FGPI controller is effective and suitable for damping out oscillations resulted from load perturbations. The current FGPI results were compared against those from a conventional proportional and integral (PI) controller, a fuzzy logic controller and a FGPI controller proposed by Chang and Fu (Chang C. S., Fu W. Area load-frequency control using fuzzy gain scheduling of PI controllers. Electr Power syst Res 1997; 42: pp. 145-152). Two performance criteria were utilized for the comparison: settling times and overshoots of the frequency deviation and absolute error integral. The comparison study indicated that the proposed FGPI controller has better performance than the other three controllers. (c) 2005 Elsevier Ltd. All rights reserved.
