Abstract

To supply good quality power, the Load frequency control (LFC) acts an important role toward the system uncertainty and disturbance elimination capability for both isolated and interconnected power systems. The fuzzy based controller has the properties such as, controlling the overshoot and rise time of the response whereas the conventional controller reduces the steady state error quickly. This makes the hybrid control actions quite suitable for the LFC. Therefore, in this work a fuzzy hybrid technique is designed to generate the controller action. Initially, the hybrid approach is tested on a single area LFC for two turbine types i.e., non-reheated and reheated and then it is extended to multi-area cases. It is observed that the proposed controller displays better robustness toward ±50% parametric uncertainty and disturbance rejection capability as compared to the existing techniques
