In power system networks, evolving operational conditions present various stability challenges, one of which is the influence of frequency deviations on system dynamics. These deviations occur due to imbalances between power generation and consumption, leading to frequency fluctuations as a result of changes in demand and generation. A key problem addressed in this study is the occurrence of over-frequency and under-frequency events within the power system. The research focuses on the effect of these frequency deviations, which are important for maintaining network stability. The aim of this research is to thoroughly examine the impact of frequency variations on power system dynamics. The method employed was analytical method, which involves identifying system components and their interactions with frequency fluctuations. MATLAB Simulink simulations are used to assess the real-time effects of frequency deviations on the power system. Data collected from these simulations are presented in tables and graphically to analyze the extent of frequency deviation within the system.

In this study, a simplified power system model was created to investigate the effects of variations in key generation system parameters—such as the equivalent system inertia (Heq), governor droop setting (Req), load damping constant (D), and the power fraction of the high-pressure steam turbine (T1/T2) on the primary frequency response. The analysis focused on the system’s behavior in addressing frequency disturbances caused by a generation loss, which was simulated to occur five seconds after the simulation began.
