Detailed Documentation

This project develops a MATLAB model of a power system comprising three synchronous generators and nine network nodes. The model serves as an analytical tool for researchers to study power system operations and dynamic responses. Implementation incorporates modern control theory and power system principles through differential-algebraic equations representing generator dynamics, load flow calculations, and network constraints. Key functions include generator governor control simulation, exciter system modeling, and power flow analysis using Newton-Raphson methods. The model's architecture features swing equation implementations for rotor dynamics and admittance matrix formulations for network solutions. This research provides significant insights for power system monitoring and control applications, particularly relevant for densely populated, rapidly developing regions like the Western United States where grid stability challenges are pronounced.
