The only input by the user here is susceptance matrix B=[NxN] and vector of injected powers P (length(P)=N), where N is the number of nodes in the network. The calculation is done both in per-unit system and in absolute system, the user is left to decide in which system will be the calculation. In the pdf file, there is a detail explanation of linear DC model, also there is a Readme file with the full explanation of using this program. This code can be used for up to 9999 nodes of a various system models, the main thing is to input the susceptance B and vector of injected powers P correctly. Latter on, there is a possibility for further calculations, when there are contingencies in the system (generator is off, line is off...) and even full N-1 or N-1-1 analysis.
