Enhanced AGC of Two-Area Power System Incorporating Diverse Power Output Control Strategies for Thermal Power Generation Utilizing Fuzzy Logic Controller
Journal Title: International Journal for Modern Trends in Science and Technology - Year 2024, Vol 10, Issue 11
Abstract
The paper presents an enhanced Automatic Generation Control (AGC) strategy for a two-area power system using a Fuzzy Logic Controller (FLC). Traditional AGC methods struggle to maintain system stability due to the nonlinear and time-varying nature of power systems. The proposed approach uses fuzzy logic to dynamically adjust control parameters, improving the system's robustness and adaptability. The two-area power system model includes thermal power plants with varying control strategies, such as governor control, reheat turbines, and supplementary control loops. The FLC is designed to process input variables like frequency deviation and tie-line power flows to produce optimal control actions. Simulation results show that the FLC-based AGC significantly enhances system stability, reduces frequency oscillations, and minimizes area control error. It also effectively damped oscillations in tie-line power flow, achieving steady-state values more rapidly. These results show that adding fuzzy logic to AGC frameworks might be useful for modern power systems that use a variety of generation sources and have changing load demands
