A Python program to reduce electrical networks

Modern transmission networks may contain tens of thousands of busbars. Joint studies involving transmission and distribution grids pose the problem of large size of the resulting system, which may make them unmanageable. This work presents a program that reduces an electrical network, keeping only those busbars where electrical energy resources are connected. The program is written in Python and can be executed by a free-software interpreter. It can by applied to distribution networks to obtain a reduced model that still contains all relevant data needed to perform dynamic studies on the transmission grid.
