hello. Could anyone suggest a software (in open access if possible) capable to simulate and identify electric network problems in interconnecting building systems. Thanks in advance.
ENS is an electric network simulator for weakly-meshed distribution networks. It was initially built as a plugin application for a loss reduction tool developed at IRI, in the course of a Master's degree project. Along the years, I've been working the code until arriving at its present form, which surely will evolve in the future with necessary enhancements.
The simulator implements, with some improvements, the sweeping/compensation method by Luo and Semlyen. As output, the simulator returns all complex bus voltages and complex branch currents. Cycles (i.e., loops, or meshes) are allowed to exist in the network, even if they have null-impedance. PV buses can also be dealt with, if treated as a special kind of loop breakpoint. The current implementation allows changing any branch state (open or closed) and recomputing only the network portion which is affected by such change.
