An improved modeling technique for distribution feeders with incomplete information

This paper proposes an improved technique for modeling of an electrical distribution system in the presence of incomplete information. By considering the different behavior and coincident factors of commercial and residential loads, this paper formulates a ratio factor technique to acquire an improved power-flow model. A load distribution relationship between the entire load and less than 50% of the total load on a feeder is also formulated. The technique only requires annual peak loads for each feeder and substation which are readily available. In addition, the method uses the results of the conventional technique and produces better results through a set of simple computation. It is shown that the accuracy of the new technique is significantly better than the traditional technique
