Implementation of LFC Based Fuzzy Logic Controller for the Tunisian Power System

This paper studies the impact of the implementation of the proportional integral controller, Ziegler-Nichols PI and Fuzzy Logic controller on the Load frequency control (LFC) of a single power system and on two-area interconnected power system with HVDC link. The dynamic performance of the LFC control is compared with Proportional Integral controller and Fuzzy Logic controller. Simulation results for the Tunisian power system interconnected to the Italian system with HVDC link prove the efficiency and the superiority of Fuzzy Logic controller compared with the conventional PI controller.
