Abstract:

Load frequency control (LFC) in power systems operation has been a major issue of concern to power system operators. This study presents the design and implementation of intelligent controllers, based on fuzzy logic (FL), for automatic generation control (AGC) of a two area hydrothermal power system. The AGC performance with intelligent controllers is compared with the performance of conventional proportional integral (PI) and proportional integral derivative (PID) controllers under a load disturbance. Comparative analysis of results shows considerable improvement in system performance with intelligent controllers following a load disturbance in either of the areas. The fuzzy controller gives better dynamic response, reduced error magnitude and minimized frequency transients.

Keywords:

Automatic Generation Control (AGC) , Fuzzy Logic Controller (FLC) , Conventional Proportional Integral (PI) , Proportional Integral Derivative (PID)
