A Classification of Power Load Based on the Load Characteristic in Distribution Networks

Nowadays the widest used classification of power load is based on the industry they belonged to, but, as low voltage loads are varietal, even the loads in the same industry can be considerably different in load characteristics of them. In this paper, power loads are classified according to three load characteristic indicators: load averages, load changing cycle and the peak-valley ratio, which are based on the typical daily load curve of them. In this method, the typical daily load curves of loads in the same type are relatively more similar, which is in favor of further study using daily load curve. In this paper, thousands of 10kV loads in shanghai have been classified into 8 types in the method, and the analysis of the load types have been presented.
