Gridlab-Dtm Software Efficiency Analysis Using The Newton-Raphson Method For Power Flow Analysis Of Electrical Systems Compared To Matlab®

The GridLAB-DTM, which was launched in 2007, and consists of an open platform developed by the US Department of Energy at the Pacific Northwest National Laboratory. Firstly, this paper presents an introduction about the platform and the development of the program, followed by the presentation of the Newton-Raphson method applied to power flow. The method is part of the mathematical scope called numerical methods, which solve systems and equations in an algorithmic way, and indicates the desired precision as a stop method for the sequence of iterations performed by the method. This work was developed with the objective of analyzing the effectiveness of the GridLAB-DTM in the power flow analysis. This exam takes into account the interface, usability, execution time and accuracy of results offered by the program. The program successfully resolves the analysis of the proposed system in 10 seconds, while the same logic run in Matlab® has an execution time of 2 minutes. This time is considerably significant given the complex logic of the programs. In contrast to Matlab®, GridLAB-DTM is an open platform graphical program, while this first program is costly and does not allow modification by the user.
