This present work deals with the performance of the fuzzy logic controller (FLC) for a multi-area automatic load frequency control system. At the start, thermal, hydro, and gas units in each area are considered in a three areas’ nine-unit power system and appropriate area participation factors are assumed for each unit. After that, fuzzy logic controllers having triangular member functions are incorporated as a secondary controller to attain a better performance of the system. The effectiveness of the FLC is observed while compared with a classical PID controller. In addition, the capability of considered FLC controller is also exhibited by considering random step load disturbance.
