Decomposition of load components using data measured in the beginning of subtransmission substations

Usually, in the beginning of substations and medium-voltage feeders, the profile of loads is measured that is related to the total load of an area (or many of customers). There are various methods to decomposition of load profiles of different classes of customers. These methods need typical load profiles. Also they use simplifier assumptions that limit their application to the real data. In this study, a novel method based on independent component analysis is proposed. The basis of using this method is the statistical independence of load components of different classes of customers. The proposed method decomposes the load components from the total measured load of a feeder and then calculates the share of each component of the total load profile. To verify the method, 24 h load curve of the feeders of a sample network is simulated and then the method is applied.
