Two-Area System AGC (Automatic Governor Control) MATLAB Simulation

The ZIP file contains comprehensive documentation detailing the two-area power system architecture along with a MATLAB simulation of the Automatic Governor Control (AGC) system. The simulation implements primary and secondary frequency control mechanisms using transfer function blocks and state-space representations to model generator dynamics, load variations, and area control errors. Key algorithms include proportional-integral controllers for frequency regulation and tie-line bias control for maintaining inter-area power balance. The documentation offers technical insights into system design parameters, governor-turbine models, and stability analysis under various disturbance scenarios. The simulation enables users to analyze dynamic responses to load changes, validate control strategies, and optimize controller gains through parametric studies. Implementation features include modular subsystem organization, real-time performance monitoring plots, and configurable disturbance inputs for testing system robustness. This resource provides practical understanding of AGC implementation challenges, including time-delay compensation, dead-band effects, and coordination between control areas. The code structure demonstrates industry-standard practices for power system stabilization, making it applicable for research and industrial power system automation projects.
