Implementation of STATCOM in IEEE 30-Bus System

This project implements STATCOM (Static Synchronous Compensator) in the IEEE 30-bus power system. The program utilizes MATLAB/Simulink to model STATCOM's voltage regulation capabilities through PWM-controlled voltage source converters (VSCs). Key functions include reactive power injection/absorption algorithms and proportional-integral (PI) controllers for maintaining bus voltage stability. The program focuses on solving power system stability issues using STATCOM technology. STATCOM operates as a static compensation device that enhances system stability and reliability through dynamic voltage and reactive power control. By deploying STATCOM in the power network, we achieve rapid reactive power response and voltage regulation, thereby improving dynamic response and power quality. This implementation uses the IEEE 30-bus system as the test case - a standard benchmark system comprising 30 buses and 41 branches. The simulation evaluates STATCOM's effectiveness through power flow analysis algorithms (Newton-Raphson method) and dynamic simulation scenarios. The code includes contingency analysis modules to test system performance under different operating conditions and fault scenarios. Through this project, we investigate STATCOM operational principles using mathematical modeling of switching converters and control system design. The MATLAB implementation features modular code structure with separate functions for: 1) Power flow calculation using admittance matrix formulation 2) STATCOM control logic with phase-locked loop (PLL) synchronization 3) Performance metrics calculation for voltage deviation and power loss analysis This program provides power system researchers and engineers with practical insights into STATCOM applications, offering hands-on experience in FACTS device implementation. The simulation results demonstrate how STATCOM contributes to modern power system optimization and stability enhancement.
