The load frequency control (LFC) system is the center of attention in this study because of the critical role it plays in regulating power generation and demand. The need for accuracy in implementing the LFC system has increased because to the rising uncertainties related to renewable energy sources and changes in demand patterns. The paper examines the dynamics of LFC in a hybrid power system consisting of a photovoltaic (PV) system and a reheat thermal system, operating in two areas. The desire to improve system performance leads to the implementation of a proportional- integral (PI) controller. In addition, the paper presents the implementation of a novel optimization technique called artificial rabbits optimization (ARO) to adjust controller parameters. There has been no exploration of this approach in LFC procedures. The optimization approach utilizes a revised objective function known as the integral time-multiplied absolute error (ITAE). The study involves conducting comparative evaluations, where the performance of the ARO-tuned PI controller is compared with proven methodologies from current literature. The results highlight the superiority of the suggested technique, demonstrated by the decrease in overshoot values and the improvement in damping durations for both system frequency and tie-line power changes, in comparison to current methodologies.
