Power System Toolbox (PST) Version 3 for MATLAB

This document introduces an exceptional MATLAB power flow program: PST (Power System Toolbox, Version 3). Designed for streamlined power system analysis, the toolbox incorporates numerically efficient algorithms for load flow calculations using Newton-Raphson methods and includes comprehensive user manuals with code examples for easy adoption by beginners. PST delivers multiple power system analysis capabilities including power flow analysis, transient stability simulation (using time-domain integration methods like trapezoidal rule), and small-signal stability analysis (via eigenvalue computation). Furthermore, PST provides customizable component models (e.g., generator, load, and transformer models) with modular MATLAB function structures, allowing users to accurately simulate diverse power system scenarios. The toolbox employs object-oriented programming principles for system data management, ensuring scalable and maintainable code architecture. In summary, PST is a powerful yet user-friendly MATLAB-based toolkit ideal for academic and industrial power system studies, featuring well-documented source code and predefined analysis workflows.
