This work demonstrates the new simulation approach for unbalanced distribution networks. An open source software Ngspice and Python language associate the new distribution network calculation method. Using the proposed circuit models, the simulation results of the proposed method are with high accuracy compared with the test results of the IEEE 4-bus system and OpenDSS. Moreover, the voltage waveform in the neutral line voltage and its harmonic analysis are accomplished, which is not possible in the OpenDSS software. The outcomes of this work provide a friendly and practical approach for polyphaser power system simulation.
