Abstract : This paper proposes Load Frequency Control (LFC) for a two-area interconnected power system using Non- dominated Sorting Genetic Algorithm II (NSGA-II). A PID controller is employed, and its parameters are optimally tuned through multi-objective optimization considering ITAE and control effort. Simulation results show that NSGA-II significantly reduces frequency deviations, settling time, and overshoot compared to conventional tuning, ensuring improved system stability.

Keywords : Load Frequency Control (LFC), Two-Area Non-reheat Power System, NSGA-II, PID Controller, ITAE, Frequency Deviation, Settling Time, Overshoot, Tie-Line Power Flow.
