Graphical Software for Power System Voltage Stability Research

We have developed a MATLAB-based graphical software solution specifically designed for power system voltage stability research. The software features complete source code availability and supports multiple implementation approaches including modal analysis, continuation power flow methods, and voltage stability indices calculation. Users can gain deeper insights into power system voltage stability mechanisms through interactive visualization tools that plot PV curves, QV characteristics, and eigenvalue distributions. The software architecture employs object-oriented programming for power system component modeling and includes functions for load flow analysis, contingency assessment, and stability margin calculation. With its high degree of user-friendliness, the interface allows intuitive operation and customization capabilities where users can modify algorithm parameters, integrate custom stability criteria, and extend functionality through MATLAB's scripting environment. The software serves as a comprehensive tool for conducting thorough voltage stability studies, enabling users to better understand and analyze power system voltage performance through both theoretical frameworks and practical simulation scenarios.
