Power System Simulator's Performance Comparison Using Load Flow and Short Circuit Analysis as Case Study

Digital Twin is the virtual representation of an object in the real world, which can simulate its behavior and characteristics. The concept of Digital Twin means that modeling is essential to ease the testing of a power system. If so, then what is the best software to use in this process of making Digital Twin? This question needs an answer because different software has different features, algorithms, and specifications for the equipment used. This study aims to find which power system modeling software can perform better in two of the most used analyses of power systems, load flow analysis and short circuit analysis, which use PSS/E, ETAP, DIgSILENT PowerFactory, and PSCAD as a study case. It can be concluded from this paper that the accuracy of the software analysis is good in all software except PSCAD's short circuit analysis. The data readability is good in all software except in PSS/E and PSCAD's quick circuit analysis, and the data completeness is excellent in all software except in ETAP and PSCAD, which is somewhat lacking in short circuit analysis.
