This paper numerically evaluates the voltage drop, the current rating of the network, the voltage profile, the total active and reactive power losses, and the current rating of short circuits. The calculations of these parameters are performed at both sending and receiving ends of a practical feeder in an extensive network in Hamadan city in Iran, with more than 180 load points. Regarding the desired parameters, the best Substations is selected to supply the feeder. The numerical analyses are formulated in Microsoft Excel software. The numerical results highlight the fact that there is a good agreement between numerical outcomes and published data in which professional software is used. It is shown that the proposed numerical method can be utilized with excellent outcomes instead of studying power distribution networks using professional commercial software. The outcomes ensure that the numerical results are satisfactorily accurate, and the evaluation of the distribution network can be conducted in a short time. Besides, due to the compatibility of data, the results can be post-processed effortlessly in other software such as MATLAB. Consequently, compared to the conventional methods, the numerical proposed method is predominantly cost-effective in terms of evaluation of power distribution networks.
