This program finds the Ybus matrix of a power system, the folder has 4 test cases (the 5, 6, 9 and 14 ieee bus systems), the data of the test cases is given on the per unit system on a 100 MVA base.
The program can be applied to accurately find the admittance matrix of more test cases, you just need to define the case information in the bus and line matrix; to compute the Y matrix, information of the transmission lines (pi model) data, transformers settings, and reactor elements are used.

Version Published Release Notes
1.0.2

It includes more test cases, and the program was written so it can be used to compute Ybus in more power systems just by providing the bus and line matrix

1.0.1

It includes more test case, also the code was made so it could work with more test cases, you just need to define the line and bus data.
