An intelligent fuzzy logic controller applied to multi-area load frequency control

Continuous load perturbation in power systems network affects the frequency directly. If the system load frequency control (LFC) mechanism is working perfectly, the frequency is quickly returned to the normal operating point. Many types of controllers have been employed for the LFC but due to non linearity of power system components and generators, the response are not usually fast and efficient. The fuzzy logic controller which is based on human expertise knowledge is employed in this paper to overcome all the setbacks witnessed in all the other controllers. The result shows an improved performance in terms of rise time, settling time, steady state error and overshoot.
