Cooperative control of AVR and GOV for improving transient stability of power systems using fuzzy controller

Abstract

The authors propose the cooperative fuzzy controller of AVR and GOV to improve the transient stability of power systems. The fuzzy rules to stabilize the power systems are selected from general ideas based on the sliding mode controller. Both the AVR and GOV input are determined to satisfy the system's stability and reduce the chattering effect in the essential problem of sliding mode. Therefore, this fuzzy controller acts to improve the transient stability of power systems. By introducing the ideas of sliding mode control, the fuzzy rules can easily be constructed systematically.<>
