A Novel Open Source Power Systems Computational Toolbox

This paper presents an open-source MATLAB-based toolbox for power systems analysis called the Power Flow Equation Solver (PESOL). This package incorporates modules such as a robust Load-Flow solver, blocks for calculating loadability/transfer capability margins through an adaptive Continuation Power Flow and Direct-Method approaches, and a Homotopy Continuation procedure for calculating solvability and feasibility boundaries of the Power Flow equations. All the algorithms within these modules are programmed to achieve computational tractability and numerical stability compared to the approaches from the literature. The effectiveness and performance of the PESOL package are assessed on a variety of IEEE schemes with different scenarios.
