Latest Power System Analysis Software Package V2.1.8

The latest Power System Analysis Software Package V2.1.8 incorporates the following core functionalities:

- PF - Power Flow Calculation: Computes steady-state power distribution across electrical networks using Newton-Raphson or Fast-Decoupled algorithms for solving nonlinear equations.

- CPF - Continuation Power Flow: Analyzes system behavior under progressive load variations through predictor-corrector methods to trace P-V curves and determine voltage collapse points.

- OPF - Optimal Power Flow: Employs optimization algorithms (e.g., interior-point methods) to minimize generation costs while satisfying operational constraints through objective function formulation.

- SSSA - Small-Signal Stability Analysis: Performs eigenvalue analysis on linearized system models to assess oscillatory stability using state-space representation techniques.

- TDS - Time-Domain Simulation: Solves differential-algebraic equations using numerical integration methods (e.g., trapezoidal rule) to simulate dynamic responses to disturbances.

- GUI - Graphical User Interface: Provides interactive visualization tools for network topology editing, result plotting, and simulation parameter configuration via MATLAB App Designer or similar frameworks.

- GNE - Custom Model Development: Allows user-defined component modeling through object-oriented programming approaches, supporting dynamic linking and custom function integration.

Extensively validated, the toolkit successfully handles large-scale systems exceeding thousands of nodes. With completely open-source code architecture, researchers can modify core algorithms and extend functionality through modular class libraries and API interfaces for specialized applications.
