This paper explores the efficacy of the Integral Square Error (ISE) criterion in the context of Load Frequency Control (LFC) for a single-area power system. As modern grids face increasing volatility due to fluctuating demand, the need for robust controller tuning becomes paramount. We present a comparative analysis between the ISE technique and traditional trial-and-error methods for optimizing Proportional-Integral (PI) controllers. Through MATLAB-based simulations, the performance is evaluated based on settling time, peak overshoot, and steady-state error. The results indicate that the ISE-based approach significantly minimizes large initial transients, providing a more stable and faster recovery for the system frequency following a load disturbance.
