Stability Analysis for 9-Bus Power Systems

Simulation and analysis of a 9-bus system, including impedance modeling, stability analysis, and parameter tuning for academic research.

Overview This project provides a complete simulation and analysis framework for power system stability, including model validation, impedance analysis, and parameter tuning.

Main Folders & Scripts

Model_validation:

Case_9_bus_system.slx: The main Simulink model. (Note: Run initial.m first for parameter initialization).

Yget.m: Impedance modeling script.

Validation_plot.m: Script for verifying model accuracy.

Analysis:

Case_analysis.m: Core system analysis.

Note: Parameters Ji and kidcr in this folder's Yget.m are specifically modified for analysis purposes.

Parameter_tuning_verification:

Step 1: Run Plot_measure.m to obtain simulation results.

Step 2: Run Comparison_plots.m to generate the comparison figures.

System Requirements

MATLAB Release: R2023b or later.

Note: Due to Simulink compatibility, the .slx files may not open in versions earlier than R2023b.
